New data on the structure of proteins. Works by Kosse1 and Schenck based on Schenck's articles. (Naturwissensch. Hf. 39,824, 1930. and Arch. F. Exp. Path 150, 160, 1930). The works are interesting both from the point of view of the spontaneous penetration of dialectical attitudes into science, and from the point of view of changing our ideas about proteins as substances that have a certain structure formula during the life cycle.
