Mytilus muscle gains base when immersed in solutions of cations in the order Li< Na< NH4 < K; Ca < Sr < Ba. The physiological activity varies not in the order of the swelling produced by ions, but the gain in base. This gain of base appears to be determined by permeability. As the exciting and inhibitory power of ions varies in the same order, it is therefore concluded that excitation or inhibition depends upon a common factor, such as the permeability of the membrane. It is suggested that the mechanism of absorption and secretion by cells depends upon its colloidal reactions.

A complete description of the new autosomal gene in Drosophila pseudoobscura-thorax (th) that partly overlaps wild type and affects the thorax, and its appendages, along with its linkage data is given. It is shown to be located on the third chromosome-22·4 units to the right of orange (or).

Fractional gastric analysis, using Boas meal, has been done in 100 normal Mysoreans (80 men and 20 women) between 20 and 25 years of age.
Free acid, total acid and total chlorides have been estimated in the resting juice and in all fractional samples. Emptying time is noted.
A difference in the gastric response in the two sexes, observed by other investigators, has been confirmed.
No appreciable difference is observed in the gastric responses of people on vegetarian and mixed diets.
There was no case of achlorhydria in our series.
Depressant action of physical strain before gastric analysis on acid secretion has been pointed out.
Standard reference charts for men and women, to show the range of variation in maximum HCl response throughout the gastric cycle in 80% of cases are given.
