ANTISEPTICS. 889 amounts, but it is likely that the proteid directly connected with glycocoll will be found to be highly melassigenic.We have been in the habit of associating the so-called gums or viscous bodies in cane juice with the cellulose or non-nitrogenous constituents of the plant, but we may have to modify this view in the presence of a gelatin-yielding proteid peculiar to sugar-cane and allied plants.
CHARLES F. MABERY. strength as those ordinarily used in manufacture. Care must be taken, however, that the solvents are free from all matter not volatile at ioo°C.
INCE all asphaltic bodies are complex mixtures of hydro-s carbons with different melting-points, it is evidently quite out of the, question to determine even approximately the meltingpoints of the asphaltic mixtures. The elements of time and temperature must be taken into account. A product that softens
23 chemical series. Aluminum forms a notable exception. In spite of the high position of this metal in the electrochemical series, its salts invert sugar more rapidly than those of any other metal thus far tested. 3. Chlorides invert sugar more rapidly than sulphates, because the ionizing tendency of chlorine is greater than that of the sulphuric radical.
105tion Hugo Haedrich, Ztschr. phys. Chem., 12, 496). There is doubtless, therefore, a close connection between the phenomena outlined above, and others depending on the degree of dissociation of the ions in solution. A study of the behavior of weaker solutions would doubtless lead to interesting results not brought out in the above experiments which were undertaken mainly to show the character and amount of precipitates formed. A discussion of the behavior of dilute solutions will follow.Chicago, December, 1894.
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
