1905 Annals of Surgery  
Throughout this second edition of Simon's "Physiological Chemistry" there is evidence of careful revision, especially in the chapters dealing with proteids, proteid derivatives, and proteid digestion, concerning which our knowledge is undergoing such rapid development. The work was intended, and is well fitted, to serve both as a text-book and a laboratory guide; the amount, character, and arrangement of its included matter being nicely gauged for course-study, while an appended outline of

This feature of the book is highly commendable, for in the teaching of physiologi¬ cal chemistry, as in that of any other branch of physical science, lecture-room and laboratory work should go hand in hand. No doubt the author has carefully considered the classifica¬ tion which he gives of protein substances, and that he distinctly prefers the term " albumins" as designating what are commonly called proteids is evident from the fact that he has retained the term in his second edition, while he restricts the term " proteids" to the group of substances commonly designated as compoundprotcids. This decision, or choice of terms, the reviewer cannot endorse; for the old term "proteid" is likely to remain with us, for some time at least, as designating the albumins and globulins, both native and derived, while the nuclein-containing and pig¬ ment-containing protein substances (which the author classifies as proteids) are really compound proteids, and, for the present, might be designated as proteides. As regards the peptones (which, with the albumoses, fibrin, and the coagulated proteids,
