    Notes: Summary The appearance and development of tumors of mammary glands in female mice of the highly-cancerous line C3HA was studied. The peculiarities of the higher nervous activity were investigated with the aid of the motor food method (E. A. Ganike-1935, 1939 and 1941 and V. K. Fedorov-1951). The following was established. 1. There is a direct relationship between the degree of mobility of the nervous processes and the resistance of the organism to the “milk factor.” This alone was detected only in definite conditions of keeping and investigation of animals. 2. The same relationship exists between the process of metastasis and the degree of mobility of the nervous processes, i. e., mice with inert nervous processes prevailed among the animals with metastases of the tumors.

    Description / Table of Contents: Zussamenfassung Um die Erklärung, welche uns privat mitgeteilt wurde, zu prüfen, dass der ausgesprochene Einfluss der Luftstromgeschwindigkeit auf die Grösse des mit der dynamischen Methode bestimmten Diffusionskoeffizienten der verschiedenen Durchströmung der Kanäle des bisher verwendeten Diffusionsapparates zuzuschreiben ist, wurde ein neuartiger Diffusionsapparat, den wir «Universelle Diffusions Batterie» nennen, konstruiert, in welchem die Luftstromgeschwindigkeit durch jeden Kanal gleichgemacht werden kann. Die neue Diffusionsbatterie und ihre Vorteile werden beschrieben. Ihre Anwendung zeigt, dass auch mit gleicher Luftstromgeschwindigkeit durch jeden Kanal die Abhängigkeit der Diffusionskoeffizienten von der Luftstromgeschwindigkeit — nämlich, dass höhere Diffusionskonstanten mit grösseren Luftstromgeschwindigkeiten erhalten werden — doch besteht. Es werden die Resultate einer Vergleichung der Werte des Diffusionskoeffizienten, wie siebei Benützung der Diffusionsapparate der alten und neuen Bauart erhalten werden, mitgeteilt. Die Erklärung, welche sich auf unwiderlegbare theoretische Überlegungen stützt, dass die Abhängigkeit des Diffusionskoeffizienten von der Luftstromgeschwindigkeit durch die Heterogenität der Kondensationskerne verursacht wird — wie sie vor einiger Zeit vonPollak & Metnieks, gegeben wurde — scheint die richtige zu sein oder erfasst wenigstens den grössten Teil der Erscheinung.
    Notes: Summary In order to examine the explanation put forward to us privately that the marked influence of the air-flow on the value of the diffusion coefficient as determined by the dynamic method is due to unequal flow through the channels of the diffusion apparatus used hitherto, a novel diffuser — called Universal Diffusion Battery — has been constructed in which the air-flow through each channel can be equalised. The new diffusion battery is described and its advantages outlined. Its application also shows that with equal flow through each channel the dependence of the diffusion coefficient on the air-flow (i.e. that higher diffusion constants with higher flow rates are obtained) still exists. A comparison of the diffusion coefficients as measured with the diffusion batteries of the old and new types is given. The explanation based on irrefutable theoretical considerations that this dependence of the diffusion coefficient on the air-flow is caused by the heterogeneity of the condensation nuclei in the aerosol, as given byPollak & Metnieks some time ago, is apparently the correct one or it accounts at least for the greatest part of the phenomenon.

    Description / Table of Contents: Summary A report is given of a simple and rapid method for determining fluorine. In this, the lead chloride fluoride precipitate is dissolved in Complexone III solution and its chloride content is titrated directly with silver with variamin blue acetate as redox indicator. The procedure may be employed successfully also for determining fluorine in organic compounds.
    Abstract: Résumé Description d'une méthode simple et rapide de dosage du fluor reposant sur la dissolution du précipité de fluochlorure de plomb dans une solution de complexon III et détermination de la teneur en chlore par titrage argentométrique direct en présence de l'acétate de bleu de variamine comme indicateur redox. Il est possible d'utiliser également cette méthode pour le dosage du fluor dans les combinaisons organiques.
    Notes: Zusammenfassung Es wird über ein einfaches und rasches Fluorbestimmungsverfahren berichtet, wonach der Bleichloridfluoridniederschlag in Komplexon III-Lösung gelöst und sein Chloridgehalt in Anwesenheit von Variaminblauacetat als Redoxindikator direkt argentometrisch titriert wird. Das Verfahren läßt sich auch zur Fluorbestimmung in organischen Verbindungen mit gutem Erfolg heranziehen.

    Description / Table of Contents: Summary A micro method is described for the direct titration of the halogen content (Cl, Br, I) of organic compounds —following combustion in oxygen —in the absorption liquid with 0.01N silver nitrate. The endpoint is signalled by means of variamine blue acetate as redox indicator. The sulfur and chlorine contained in organic compounds can be determined in the same sample, provided the sulfate ion in the absorption liquid is first determined by means of barium perchlorate solution by the method ofI. S. Fritz andS. S. Yamamura, orE. Wagner. The chloride ion content can then be measured directly by argentometric titration as described in this paper.
    Abstract: Résumé Description d'une méthode de microdétermination de la teneur en halogènes (Cl, Br, I) de combinaisons organiques par combustion en atmosphère d'oxygène et titrage direct dans le liquide absorbeur par une solution de nitrate d'argent 0,01N. Le point final du titrage est détecté par l'acétate de bleu de variamine utilisé comme indicateur d'oxydoréduction. Les teneurs en chlore et en soufre peuvent être déterminées sur la même prise d'essai si l'on dose, dans le liquide absorbeur, tout d'abord les ions sulfate par une solution de perchlorate de baryum d'aprèsI. S. Fritz etS. S. Yamamura ou encoreE. Wagner, puis les ions chlore par argentométrie directe d'après la précédente technique.
    Notes: Zusammenfassung Es wird ein Mikrobestimmungsverfahren beschrieben, wonach der Halogengehalt (Cl, Br, J) organischer Verbindungen — nach Verbrennen in Sauerstoffatmosphäre — in der Absorptionsflüssigkeit mit 0,01-n Silbernitratlösung direkt titriert werden kann. Der Endpunkt der Titration wird mit Hilfe von Variaminblauacetat als Redoxindikator angezeigt. Der Schwefel- und Chlorgehalt organischer Verbindungen läßt sich aus derselben Einwaage bestimmen, falls in der Absorptionsflüssigkeit zuerst die Sulfationen mit Bariumperchloratlösung nach dem Verfahren vonI. S. Fritz undS. S. Yamamura bzw.E. Wagner und sodann die Chloridionen nach dem vorliegenden Verfahren direkt argentometrisch titriert werden.

    Notes: Summary We noticed the formation of a precipitate on adding salmine to dilute aqueous protein solution at pH 6–7. Human and bovine serum albumin, human γ-globulin, and the perchloro- and sulfosalicylosoluble mucoides do not precipitate in this condition. α- and β-lipoproteins prepared by floatation and by Sandor's technique gave S-shaped nephelometric titration curves, as did haptoglobin, a mixture of the types Hp II-Hp II and Hp II-Hp I. In sera incubated 24 h at 37°C with protamin, the dextran sulphate test and the cetavlon test show a diminished value for β-lipo- and α-glucoprotein. Lipoprotein degradation is probably enzymatic in nature.
