Abstract
Journal of the Russian chemical and Physical Society, vol. xxiii., No. 1.—The chief papers are:—On the molecular weight of albumen, by A. Sabanéff and N. Alexandroff. Several determinations were made on the method of Raoult, and gave an average of 14,276, the molecular weight thus appearing to be nearly three times as great as that deduced from the formula of Harnack (4730), and nearly nine times as high as that given in Lieberkühn's formula (1612). The molecule contains nine atoms of sulphur, of which two are easily separated. Submitted to a temperature of 40°, the solution of albumen changes its properties, and its temperature of freezing is lowered.—On the measurement of density of sea-water, by Vice-Admiral Makaroff. This elaborate work gives the results of measurements made on board the corvette Vityaz. The value of various instruments used during the cruise is discussed in detail, and the following formuæ are given as expressing the results of the observations between the temperatures of 0° and 30°. For distilled water, the density is—
