    Notes: This study is concerned with the interrelationship existing among the polymorphie soldier castes of six representative subgenera of the genus Nasutitermes. By measurements of anatomical parts and camera-lucida drawings, an attempt has been made to compare these particular subgenera on a basis of gradual divergence of certain structures. For this purpose a series of tables was compiled in which apparently unstable structures were compared to a relatively stable figure in all available species of the selected subgenera.According to my findings, it was concluded that there is no strict correspondence between the major, intermediate, and minor castes of different subgenera of the genus Nasutitermes. Particular reference is made to the work of N. Holmgren ('12) and to that of J. S. Huxley on heterogonic growth.

    Notes: There are twenty-seven spermatogonial chromosomes in Tenoder'a sinensis, three of which are larger than the others and lag behind in anaphase. These three chromosomes have been traced through the prophases of the first spermatocyte to the metaphase, where they appear as a hexad. In the first spermatocyte division two of the constituent diads of the hexad pass to one pole, the remaining one to the other, thus giving rise to two types of second spermatocytes, one with thirteen and the other with fourteen chromosomes. There are twenty-eight chromosomes in somatic metaphases of the female; four of these chromosomes are larger than the others. The sex chromosomes of the male are represented by the formula Xa + Y + Xb, that of the female by 2Xa + 2Xb.Similar conditions are reported for Mantis religiosa and Stagmomantis carolina.

    Notes: Some pathological effects of supersonic waves produced by the piezo-electric oscillator described by Wood and Loomis ('27) are described.Death of fish and frogs was due to haemolysis of erythrocytes within the gill capillaries. Disruption of gill filaments, trauma, and extravasation in the head and gill region and in the peripheral musculature were noted.No effect on the nervous system was apparent histologically.Organisms were not killed in water under hyper- or hyponormal pressures. In these cases no cavitation of gases took place.Isolated frog sartorius muscle in Ringer's was not damaged.Bubbles of gas were easily observed within the muscle cells of the tadpoles when such cells were not more violently disturbed. Such bubbles were abundant in the more fluid muscles of four- or five-day tadpoles, less abundant in 15- to 35-mm. Lebistes, and entirely lacking in adult frog sartorius. Protoplasmic viscosity differences probably explain the gradient.The above-observed intracellular cavitation explains the muscular destruction, the haemolysis, the change in specific gravity of organisms subjected to the wave treatment, and may offer light upon the stimulatory effect of such waves on excitable tissues (compare Harvey, '28).

    Notes: 1. Potentiometrisch kann Jodid entweder so bestimmt werden, daß man unter Zugabe von Tetrachlorkohlenstoff bis zum ersten Wendepunkt beim Verbrauch von 1 Val Permanganat auf 1 Mol Jodid titriert oder ohne Zusatz bis zum zweiten Wendepunkt, der beim doppelten Verbrauch eintritt. Sind auf 1 Mol Jodid nicht mehr als 10 Mol Bromid vorhanden, so ist die erste Art unbedingt genauer; bei höheren Bromidüberschüssen hängt es von den Eigenschaften des benutzten Potentiometers ab, welches Verfahren bessere Ergebnisse liefert.

    Notes: Es wird zuerst eine kurze Zusammenfassung über einige Ergebnisse beim Studieren der Platzwechselreaktionen gemacht. Die Rolle der Ionendeformation als Gitterauflockernder Faktor wird diskutiert, und es wird nachgewiesen, daß der Einfluß auf die Reaktionsfähigkeit des festen Zustandes, der geringen Deformierbarkeit der Anionen der Sauerstoffsäuren wegen, bei Reaktionen mit Halogeniden vie1 größer und leichter zu studieren ist als bei Reaktionen mit Salzen der Sauerstoffsäuren. Mit den letzteren konnte eigentlich nur ein Unterschied zwischen Salzen mit Kationen vom Edelgastypus und vom Nichtedelgastypus unterschieden werden. Die Reaktionsfähig keit der Halogenide ist aber in weit höherem Grad individuell. Ein neues Beispiel von der Regel, daß die Reaktionsfähigkeit einer Verbindung während einer kristallographischen Umwandlung erhöht wird, wird gegeben (BaO + AgJ). Eine Reihe Umsetzungsmessungen bei Reaktionen von Erdalkalioxyden (BaO, CaO) mit Halogeniden von Cu+, Ag+, Tl+, Pb++ und Ni++ werden mitgeteilt und der Zusammenhang zwischen Reaktionsfähigkeit und elektrischer Leitfähigkeit im festen Zustande nachgewiesen und diskutiert; die Rolle der Ionen braucht dabei nicht notwendig eine direkte zu sein. Es wird wahrscheinlich gemacht, daß der Charakter dieser Reaktionen als Ionen- oder Nichtionenreaktionen leichter mit geschmolzenen als mit festen Halogeniden studiert wird.
