    The effects of certain physical and chemical factors on locomotion and others life-processes in Amoeba proteusThis investigation was suggested by Prof. S. O. Mast and carried out under his direction. He has also furnished valuable aid in the presentation of the results. For these favors, I am greatly indebted to him. (1928)

    Notes: Amoeba proteus was raised in a modified and diluted Ringer solution. When the pH of this culture medium became less than 6.0, the normal activities of the amoebae were interfered with; and when a still lower pH was attained, the amoebae died off. The same was true when the pH became greater than 8.0. At neutrality the activities were subnormal, very dark, and rounded. The rate of locomotion of amoebae raised in solutions with a pH less than 7.0 showed a maximum rate of locomotion at pH 6.6, which decreased as the pH changed in either direction, dropping to a very low rate at pH 7.0 and above and also below 6.0. For amoebae raised at a pH above 7.0 the rate was maximum at pH 7.6 and decreased as the pH changed in either direction; it was low at pH 7.0 and below and also above 8.0.On increasing the external osmotic pressure of the medium it was found that the effects caused varied somewhat with the hydrogen-ion concentration. Small increases in osmotic pressure decreased the rate from the normal at pH 6.0 and 8.0, increased it at pH 6.6 and 7.6, and did not affect it at pH 7.0. Osmotic pressures above that produced by M/20 lactose caused locomotion to cease in a short time at all pH values.

    Notes: The highly specialized cranial musculature of the toadfish is characterized by the following features: 1Absence of intermandibularis and branchiomandibularis muscles.2Presence of levator premaxillaris muscle.3Very large branchial chamber, the outer wall of which is formed by seven branchiostegal rays connected by a strong fascia provided with muscles (oblique levators and adductors).4Highly developed masticator muscles (adductor mandibularis and pterygoids).5The rectus abdominis, sternohyoid, and hyohyoid muscles are attached by a median aponeurosis to the hyoid and basibranchial elements and directly to the hypobranchial cartilages; this muscle complex depresses the buccal floor in opposition to the geniohyoid.6The pelvic fins are in the jugular position.7Two narrow muscles connect the cleithrum with the fourth ceratobranchial.8The cranial musculature is obviously adapted to a carnivorous habit and particularly for increasing respiratory capacity under asphyxial conditions.

    Notes: Blindfolded persons walk, run, swim, row, and drive automobiles in clock-spring spiral paths of greater or less regularity when attempting a straightaway. The spirals turn either right or left in one and the same individual, and may do so even in one experiment. But either right or left turns predominate in the great majority of individuals, often to a high degree. The paths show marked individuality, and there is some ground for thinking there exists a correlation between temperamental differences and general character of path.The mechanism which produces the spiral path is not located in the locomotor organs, but in the central nervous system and is probably identical essentially with the spiral mechanism in other motile organisms, all of which move in spiral paths when there are no guiding senses to direct the path. The clock-spring spiral in man is interpreted as the expression in two dimensions of space of a helical spiral mechanism which seems to exist in all motile organisms moving in three dimensions of space and in amebas which move in two dimensions. In a large number of lower organisms the number of body lengths per spiral turn is almost constant, being about 4.5. The smallest regular swimming spirals in man are very close to this value, but the smallest regular walking spirals are somewhat larger. The fundamental spiral mechanism seems to be of molecular dimensions, and there seems to exist a demonstrable locomotor bilateral asymmetry in very nearly, if not quite, all organisms.

    Notes: A detailed study has been made of the anatomy of one of the fingernail shells, and preliminary observations on the life-history have been carried out. In its general organization Sphaerium notatum is very similar to the larger fresh-water lamellibranchs. A gastric shield, crystalline style, and style sac, very similar to those found in the stomach and intestine of Lampsilis, are present. A pair of slender muscles extending from the dorsal side of the body into the gills, and evidently not previously described, have been found. The nervous system consists of the typical three pairs of lamellibranchiate ganglia, with their connectives, accessory ganglia, and nerve fibers. Particular study was given to the statocysts and osphradia, and attention is called to the fact that the function commonly ascribed to the osphradia is incompatible with their position in the roof of the cloacal chamber.S. notatum, like all the Sphaeriidae, is hermaphroditic and viviparous. The gonads are paired racemose glands lying behind and below the stomach. The sperm-producing follicles form the anterior portion of each gonad and are somewhat smaller and more numerous than the ova-producing follicles which form the posterior portion. The young pass through the early stages of development in brood pouches in the gills and are expelled as relatively enormous individuals.Preliminary observations on the life-history indicate that reproduction reaches its height in the summer and that fertilization probably takes place during the late summer and fall.

    Developmental factors in teleost hybrids. I. The early mitotic behavior in the cross between menidia menidia notata ♀ and Prionotus carolinus ♂ (1928)

    Notes: When Menidia eggs are fertilized with Prionotus sperm, the Prionotus chromosomes react in the Menidia cytoplasmic medium just as they do in the cytoplasm of Fundulus eggs. There is lagging, non-disjunction, and elimination of chromosomes during the early cell divisions. The mitotic behavior of the Prionotus sperm in the Menidia egg also resembles the behavior of the sperm of Ctenolabrus in the same medium. This behavior which was expected from what was known concerning the mitotic behavior of the reciprocal crosses between Menidia and Fundulus and between Ctenolabrus and Prionotus and other intercrosses between the members of these two groups is regarded as a function of the physical state of the egg cytoplasm during the division phase of mitosis. This physical character forms the earliest differential factor in the development of these hybrids and shows no correlation with the width of the cross.A comparison of nine teleost crosses, in which both the development and the early mitotic behavior are known, with a rough numerical estimate of the width of the cross brought out the fact that development is most successful in crosses between nearly related species if mitosis is normal and in distantly related crosses if mitosis is abnormal. This indicates that nuclear relationship is also a factor in the development of hybrids.

    Notes: Virulent hay-infusion cultures of Bacillus pyocyaneus are toxic to pure-line races of three species of paramecia, but these races may acquire a tolerance for this toxic agent. Races with acquired tolerance have been grown for long periods of time in toxic, pure cultures of B. pyocyaneus by means of the daily-isolation culture method, and here the average division rate is as high as, or higher than, in the chance-mixed bacterial cultures in which these protozoa are usually maintained in the laboratory. The tolerance is lost, however, when the paramecia are removed from the toxic cultures and grown for a number of generations in cultures of non-toxic bacteria.The toxic agent that is lethal to paramecía is probably the soluble toxin of B. pyocyaneus. The investigation shows that the agent is soluble and either thermolabile or volatile. It also shows that all deleterious substances, other than the soluble toxin, known to be produced in cultures of this bacillus, are non-lethal to paramecia.Hay-infusion cultures of Bacillus enteritidis were lethal to paramecia. All attempts to develop tolerance in paramecia for the toxic agent in these cultures failed.Under the experimental conditions that prevailed, diphtheria toxin was found to have no appreciable effect upon the division rate or death rate in three species of paramecia.

    Notes: An histological and cytological study of the postembryonic history of the fat-body in Pteronidea ribesi (Scopoli) and Diphadnus appendiculata (Hartig) (both Tenthredinidae) and in Macrocentrus ancylivora Rohwer (Ichneumonidae).The two principal components of the fat-body are the urate-storing excretory cells and the fat-cells.The development and behavior of the excretory cells, especially during the metamorphosis, are described, and in Pteronidea their origin is traced to leucocytes which have become associated with the fat-cells.In the albuminoid inclusions found in the fat-cells two types of substance are distinguished: (a) a basophile material, of nuclear origin, which appears only during the metamorphosis; (b) an acidophile material which appears already during the early larval stages in Macrocentrus, but in Pteronidea is formed only during the metamorphosis and in association with the basophile material. It is thus found that albuminoids formed slowly during larval life may exist from the beginning in the form of acidophile spheres, as occurs in Macrocentrus. But those formed rapidly during the metamorphosis, in all the forms studied, are formed in association with a basophile material derived from the nucleus.The significance of intracellular changes during the metamorphosis is discussed, and the final disposition of the cell inclusions as well as of the fat-cells themselves is described.

    Notes: In this study the problem of the tonsil is considered in anurans. The common toad (family Bufonidae) is used as the type, and representative species of the other families are compared.In each species representative stages beginning before transformation were selected, and the lingual region of each was sectioned. Some thyroid-fed toad tadpoles which had prematurely transformed were examined. The investigations led to the following conclusions: 1Accumulations of lymphocytes occur in all the families except Hylidae.2A pair of tonsils located on either side of the tongue appear before transformation in Bufo, and persist, increasing in size through old age.3This pair has its developmental origin at or near the cephalic end of pouch II. In no other species examined do the tonsils appear as early; in almost all forms the accumulations are inconstant in occurrence, as are also some in Bufo.4The cells of the ‘tonsils’ are lymphocytes of varying sizes. They arise from the mesenchyme; later their accumulations become sites of lymphopoiesis.5This type of lympho-epithelial mass is simple in structure and has a greatly thickened epithelium, due to extensive infiltration by lymphocytes. In the connective tissue the vascular supply is abundant.6The differentiation of lymphocytes may be due to a factor of strain, arising through adjustments made during metamorphosis.7Thyroid-fed toad tadpoles transform, apparently without developing tonsils.

    Notes: The object of the present study is to determine by quantitative means the rate at which a given number of paramecia can utilize the various amino-acids and to study factors influencing this rate.The method consisted in testing the rate of utilization of isolated and mixtures of amino-acids by a known number of Paramecium caudatum. The amino-acids were used in 0.1 per cent solution and were tested, by the Henriques-Sörensen formol titration method for amino-acids, at the beginning and after the paramecia had lived in these amino-acids for twelve hours. The difference between these two tests, figured in percentage, is considered as the amount utilized by the paramecia. The part played by bacteria was found to be negligible when isolated amino-acids were studied. The influence of temperature on the rate of utilization of the amino-acids has been studied, and the results show a direct relationship between the two.The rate of utilization was decreased by anaesthetics and nitroglycerin. A careful study has been made of a number of isolated amino-acids and the rate of utilization of each discussed in relationship to the others studied. An explanation of why one amino-acid was used more than another amino-acid was sought for, but not found. A detailed discussion of the above points has been presented in the body of the paper.

    Notes: A chronological investigation of the histological condition of the right ovary of the domestic hen from embryos of nine days' incubation to adults of eighteen months was made. A rudiment of the right ovary is found at all times. Its composition is variable. Sixty-one per cent of the rudimentary ovaries contained medullary tissue only. Thirty-nine per cent had rudiments of cortex, in addition. The occurrence of cortical rudiments in embryonic stages is the probable basis of ovarian follicles found in the rudimentary right ovaries of adults. Primordial germ cells persist in the medullary tissue until three weeks after hatching. They subsequently appear to atrophy. The medullary cords persist through the entire period either as distended tubules or as solid cords of modified epithelial cells. Remnants of the right mesonephros persist as tubules and connect with the gonad by rete tubules. The mesonephric duct maintains a patent lumen.

    Notes: Material of the domestic fowl of appropriate ages, ranging from twelve hours' incubation to the adult bird, was prepared for the purpose of studying the production and development of the germ cells.The primordial germ cells arise in the extra-embryonic region anterior to the head fold in the region of the zone of junction during the primitive-streak stage. These germ cells migrate, through the blood stream, to the region of the future gonad, where they develop into the definitive germ plasm.There is no widespread degeneration of the primordial germ cells after their arrival in the gonadal region, nor is there any widespread transformation of somatic cells into definitive germ cells.

    Notes: In this study observations are reported upon the morphological differences between the three-toed and two-toed forms of sloths, as well as a comparison made of some aspects between the sloths and the other groups of the Xenarthra. Much attention has been paid to the gross, as well as the histological examination of the viscera, musculature, and the vascular and lymphatic systems.The importance of the correlation of the morphological findings with physiological studies has been emphasized. For example, the probable correlation of the vascular plexuses of the extremities with the postures and muscular activity of the different members of the Xenarthra is discussed. Much new information has been gained concerning the placentation and development of the sloths, as well as concerning the structure of the male and female reproductive tracts.

    Notes: The septomaxillary is described in certain anurans and in some of the reptiles in which it occurs. In urodeles and some anurans this bone arises by ossification of the nasal cartilages. Lack of embryological material has prevented the verification of this in the young stages of the reptiles. Adult reptiles have been examined, and in these the bone appears to be and has often been described as a ‘membrane bone.’ It is suggested, however, that the septomaxillary is originally a ‘cartilage bone,’ and that in the reptiles additional membrane bone layers form its main part and obscure its cartilaginous origin. The infolding of the bone in the anurans and reptiles until it lies in close contact with the nasal septum, and thereby loses contact with the external nasal structures, appears to be correlated with the loss of the external nasal muscles. This loss in its turn results from the adoption of terrestrial life and consequent changes in the respiratory mechanism.

    Notes: Series of injections of ovarian hormone have been made into normal and ovariectomized immature animals. Injections were made twice daily for twenty-two days. The total dose exceeded 1000 rat units per animal.Effects noted in the living animals were the appearance of reddening and swelling of the ‘sexual skin’ and change of the cell content of the vaginal smear to the interval type of the mature animal. Measurements made at operation, before and after injections, indicated considerable enlargement of both the cervix and body of the uterus. The thymus glands of the injected animals weighed significantly less than those of the controls. Histologic study of the genital tract showed extreme thickening of the vaginal walls, considerable growth of the uterine epithelium and glands, hypertrophy of the muscle layers of the uterus, and advanced differentiation of the epithelium of the uterine tubes.The ovaries of the injected normal animal were smaller and contained fewer primordial and medium-sized follicles than those of the controls. The presence of large numbers of atretic follicles, especially large flattened scars from former relatively well-developed follicles also suggests a harmful effect of this amount of ovarian hormone upon follicular development. Several stages of elimination of ova from polyovular follicles were also observed. There was marked growth in the ducts and an increase in the number of alveoli of the mammary glands.

    Notes: Fetuses from forty-three gravid uteruses from sows of known breeding dates, as well as from 448 uteruses with unknown breeding dates, were studied. Growth curves are given for weight and length of fetus and for weight of fetal membranes. The weight of the fetus first reaches that of the fetal membranes between the sixtieth and seventieth days of pregnancy. Degenerate fetuses were found in 3.68 per cent of the cases. They were found at all stages of gestation. Size of litter was found to decrease from 11.4 at the twentieth day to 6.8 at the 110th day. Also, the calculated per cent of ova lost up to each ten-day stage tends to increase as gestation advances. Crowding was found to be an important factor, but probably not the only factor, in causing degeneration. Genetic factors were probably responsible for part of the resorbing fetuses.In the study of the normal fetuses, significant correlations were found between fetus length and weight of fetal membranes, as well as between fetus weight and weight of fetal membranes. Lower correlations, but probably significant, were found between total distance (spacing) between fetuses in the uterus and weight of fetal membranes. Correlations between size of fetus and total distance between fetuses were very low. As in the case of the degenerates, crowding has an important relationship to size of fetus, but is probably not the only factor involved.

    Notes: This study deals with the seasonal distribution of protozoa (February, 1927, to February, 1928) in correlation with seasonal fluctuations of temperature, hydrogen-ion concentration, and the relative amounts of dissolved oxygen and other gases in a small fresh-water pond. Twenty-seven species of Sarcodina, thirty-one species of Mastigophora, and 109 species of Infusoria were recorded in the surface water of the pond.As found especially for Mastigophora and Infusoria, the number of species is inversely correlated with the abundance of individuals in the seasonal distribution.Higher temperatures probably accelerated the rate of reproduction, since the seasonal maxima for most of the species were recorded in warmer weather.Colonial flagellates and Zoochlorellae-bearing ciliates seemed to be favored by higher oxygen content, with a simultaneous abundance of volatile acids, especially CO2. Although hydrogen-ion concentration was limited between 6.2 and 7.05, it was probably one of the factors influencing protozoan distribution, since several species disappeared when the lowest pH was recorded. Sunlight is one of the important factors in bringing certain heliotropic protozoa to the surface.The seasonal maxima of many of the protozoa occurred during September and October, 1927, when most of the observed physical environments seemed much more favorable than in other months.

    Notes: The following species of earwigs are used in this study: Labidura bidens, Labia minor, Anisolabis annulipes, Anisolabis maritima, and Forficula auricularia.1In all species the chromosomes are divisible into, a) autosomes and, b) XY-complex.2The chromosome distribution in regular in Labidura bidens and Labia minor. The male diploid number is 12 and 14, respectively. Each has an XY-complex in which the X is a single chromosome.3In both Anisolabis annulipes and Anisolabis maritima the male diploid number is 25, or 22 autosomes and an XXY-complex. The two X components remain fused during the first spermatocyte division.4The diploid number in the male of Forficula auricularia is 25 and 24. The chromosome number is constant in the individual. The irregularity is interpreted as due to the fusion of the two X components in the individuals with 24 counts and to these X components remaining separate in the earwigs with the 25 counts.5An explanation is given for some of the variable results obtained in former studies of the chromosomes of Forficula auricularia.6The discussion considers the possible origin of the variations in chromosome numbers in the earwigs.

    Binary fission and endomixis in the Trichodina from tadpoles (Protozoa, Ciliata)A thesis in zoölogy presented to the faculty of the Graduate School of the University of Pennsylvania in partial fulfillment of the requirements for the degree of Doctor of Philosophy.An abstract of this paper has appeared in The Anatomical Record, vol. 34, 1926.

    Notes: This peritrichous ciliate lives as an ectocommensal on the skin and gills of anuran tadpoles. Its relation to described species of Trichodina is doubtful. This study was made almost exclusively on fixed and stained material. Binary fission is similar to that in other ciliates. The horseshoe-shaped macronucleus condenses, then divides amitotically. The single small micronucleus forms a spindle containing between four and six chromosomes.Endomixis is of high incidence in the free-living Trichodinae. Encystment was not observed. At the onset of endomixis, the macronucleus disintegrates into fragments which persist throughout the process. The micronucleus undergoes three rapidly succeeding mitotic divisions to form eight nuclei. There is no evidence of chromosome reduction during these divisions. Seven of the nuclei differentiate into macronuclear anlagen; the eighth becomes the functional micronucleus. Successive cell divisions - before each of which the micronucleus divides - distribute macronuclei to daughter cells. Variations from the regular process of endomixis may arise, 1) by precocious division of endomictic parents; 2) by extra divisions of the micronucleus; 3) by less than the usual number (three) of divisions of the micronucleus; 4) by hypertrophy and early differentiation of the micronucleus into macronuclei; 5) by unusual segregation of nuclei to daughters, and, 6) from miscellaneous causes.The significance of these variations is discussed in connection with the possible origin of bimicronucleate and amicronucleate races.

    Notes: Die Entscheidung der Frage, ob das zentrale Kohlenstoffatom im Pentaerythrit pyramidal oder tetraedrisch ist, hängt ab von der Richtigkeit der makroskopischen Feststellung einer polaren Achse. Die beschriebenen Wachstums- und Ätzversuche lassen im Gegensatz zu den Versuchen von MARTIN nicht auf eine polare Achse schließen. Wegen der fehlenden Polarität und des beobachteten Habitus halten die Verfasser die Kristallklasse S, und die Raumgruppe S24, für die Richtige. Für die geometrische Stereochemie von WEISSENBERG kann daher der kristallisierte Pentaerythrit nicht mehr als eine experimentelle Stütze im bisherigen Sinne herangezogen werden.

    Notes: Es wurde das System Ferrihydrogel/Essigsäure bei 20° C eingehend untersucht und dabei folgende Beobachtungen gemacht.I. Die Einwirkung der Essigsäure auf das Ferrihydrogel ist ein typisches Beispiel einer verzögerten chemischen Reaktion (ZSIGMONDY). Mit zunehmender Essigsäurekonzentration im Sol beobachtet man der Reihe nach Sorption (Chemosorption, Adsorption und Absorption), Peptisation und chemische Reaktion.1. Die Sorption hat einen periodischen Verlauf, der durch aufeinanderfolgende Maxima und Minima gekennzeichnet ist. Bei einer Acidität von 0,069 n-CH,COOH (p, = 3,05) beobachtet man ein Sorptionsminimum.2. Die Peptisation des Ferrihydrogels tritt gleichzeitig mit der Sorption (Absorption) auf und ist am stärksten bei einer Acidität von 0,035 n bis 0,153n-CH3COOH (von pH = etwa 3,2 bis 2,s). Bei einer Normalität von 0,7 9 n wird vollständige Peptisation erreicht.3. Die elektrolytbildende Wirkung der Essigsäure beginnt oberhalb 0,79 n, vielleicht schon oberhalb 0,395 n. Die Umwandlung des kolloiden in kristalloides Ferriacetat ging deutlich hervor aus:a) der dabei auftretenden koagulierenden Wirkungb) der Farbänderung der Lösungenc) der Änderung der Capillarisierungszahl,d) der zunehmenden Oberflächenspannung der Lösungen.Oberhalb der Normalität der 1,58 ist eine weitere Elektrolytbildung fraglich.

    Notes: Wenn Tantaloxyd mit Kaliumcarbonat geschmolzen und die Auflösung der Schmelze mit Chlornatrium gesättigt wird, fällt 4:3 Natriumtantalat. Nioboxyd, auf gleiche Weise behandelt, ergibt 7:6 Natrinmniobat. Die Niederschläge bilden ein schweres, weißes, mikrokristallinisches Pulver. Die Filtrate enthalten einige Milligramm Erdsäure, welche mittels Neutralisation des Carbonats zu Bicarbonat in heißer Lösung zur Ausflockung gelangen.

    Notes: 1. Das System Cadmium-Antimon wurde einer thermischer, und mikrographischen Kontrolle unterworfen; auf Grund des von früheren Autoren und von uns beigebrachten Materials wird die Frage des stabilen Vorkommens der Verbindung Cd3Sb2 einer kritischen Besprechung unterzogen, die zu dem Ergebnis führt, daß dieser Verbindung ein stabiles Existenzgebiet nicht zukommt.

    Notes: Aktive Kohle kann zur quantitativen Bestimmung der Kohlenwasserstoffdämpfe in der Luft dienen, unabhängig von den physikalischen Eigenschaften und der chemischen Natur dieser Dämpfe. Gase, wie CO und CH2 stören die Bestimmung nicht, saure Dämpfe können durch NaOH, basische durch HCl zurückgehalten werden. Die Vorbereitung der Apparatur dauert etwa 20 Stunden, die Bestimmung selbst 1 Stunde, bei 0,2 mg Dampf und mehr in 1 Liter Luft und bei einer Sauggeschwindigkeit von 60 Liter/Stunden.

    Notes: 1. Trithionat läßt sich durch Oxydation zu Sulfat mit Hilfe von Kupfersalzen quantitativ bestimmen, indem man die salzsaure Lösung des Polythionats mit 10%iger Bariumchloridlösung und 10%iger Kupferchloridlösung eine Stunde lang kocht. Diese Reaktion versagt bei Anwesenheit von Tetrathionat, Thiosulfat und Sulfit; hingegen ist die Anwesenheit von Pentathionat, Dithionat, Sulfat und Schwefel nicht störend.
