The session of the American Philosophical Society at Philadelphia during April 18 to April 20, 1912 was interesting and successful. Researcher E.A. Spitzka of the Jefferson Medical College presented the results of his study of the weight and morphologic appearances of the human brain and its several parts, resulting from a series of studies upon specimens of various races and notable individuals. Professor William H. Hobbs of the University of Michigan, in his paper on "Some Considerations Bearing Upon the Origin of Lava," called attention to the fact that the ideas generally held concerning the origin of lava have all supposed a liquid interior to the earth.
