less than perfect, that word has no other precise scientific meaning and hence has advantage as a name for this essentially unique situation. An example of the difficulties with the valence theory use of the word resonance occurs on page 26 where the usual rule is stated, “resonance can occur only among structures with the same number of unpaired electrons.’’ This unqualified statement is not true because spin-orbit coupling yields small but non-zero exchange integrals between states of different spin orientation and the general meaning of the word resonance applies to just such weakly coupled phenomena as these. Substitution of mesomerism for resonance, however, makes the statement true without qualification. I n the preface to the third edition Professor Pauling indicates t h a t certain changes were made t o increase the-value of the book t o students a t relatively early stages in their careers. A word of caution seems required a t this point.

gator will find in this book a wealth of interesting investigative leads. The book consists of chapters on the transport and metabolism of phospate, on amino acids and glucose, on the tricarboxylic acid cycle in the kidney, on the synthesis and secretion of ammonia, on organic acids and bases, and on phlorizin. All who are interested in normal renal physiology or in such functional alterations induced by disease as renal tubular acidosis, the amino acidurias and the benign glycosurias will find the book rewarding reading. Those interested broadly in bodily function will find i t a fascinating and stimulating account of modern trends in renal physiology. CORSELLUNIVERSITY MEDICALCOLLEGE ROBERTF.
