THE WASHINGTON ACADEMY OF SCIENCES 



The 86th meeting of the Washington Academy of Sciences, a joint 

 meeting with the Anthropological Society of Washington, was held in 

 the Auditorium of the New National Museum, on Monday evening, 

 October 20, 1913. 



His Serene Highness, the Prince of Monaco, gave a lecture on Re- 

 searches in oceanography and anthropology , illustrated with lantern slides 

 and motion pictures. 



The various ingenious devices used in the manifold branches of 

 oceanography were described by the speaker, and their operation on 

 his own yacht clearly illustrated by a number of moving pictures — 

 pictures that showed not only how the work was done, but also the 

 alertness and the zest of the investigator to learn new facts. 



The remarks on anthropology were confined chiefly to an account of 

 the reasons for, and uses to be made of, an Anthropological Institute 

 which, thru the speaker's generosity, is being established in Paris. 



W. J. Humphreys, Recording Secretary.

Equilibrium in the system alkali carbonate-silica, Paul Niggli of the 

 Geophysical Laboratory. Presented by John Johnston. The systern 

 M20-Si02-C02 has been experimentally investigated for the alkali 

 metals sodium, potassium, and lithium.. The changes in weight were 

 determined of mixtures of alkali carbonate and silica, under one at- 

 mosphere of carbon dioxide, at various accurately measured tempera- 

 tures. The paper appeared in full in the November Journal of the 

 American Chemical Society. The paper was discussed briefly by Foster 

 and Johnston.
