The Significance of Phosphoric Esters in Metabolism.

This consists of three lectures related to pathologic chemistry, on the significance of phosphoric esters in metabolism, given under the auspices of the Herter Lecture Foundation in 1931, in the New York University and Bellevue Hospital Medical College: The Occurrence of Phosphoric Esters in Nature, Calcification of Cartilage and Bone, and Calcification in Vitro. The lectures include a survey of past research on the subjects closely related to the problems of most interest to the author, observations and findings of his own experimental studies accompanied by descriptive plates, and postulated explanations to throw light on the mechanism of the chemistry of calcification and ossification. Tables of references are appended. The lectures are essentially of research interest.
