While this has been the traditional view, and was probably generally accepted when this "Clinic" was originally published, the recent contradictory observations of Claude Beck would seem to have merited an editorial notice. Again, the use of sodium cacodylate as a bactericidal agent in the treatment of pericarditis due to pyogenic organisms is probably to be considered out-of-date in the modern era of sulfonamide drugs, and a parenthetical comment would have given this discussion a more modern flavor. Also, in the otherwise excellent chapter on "Treatment and Management" it might have been desirable under the section on Digitalis to include at least a foot-note calling attention to the recent official increase in potency of the U. S. P. drug. The author's stated purpose in presenting the book is the same as that which actuated him several years ago to initiate the periodical Cardiac Clinics; namely, "to present concise, practical discussions dealing with the heart, intended primarily for the busy general practitioner of medicine who is usually accorded little consideration by medical authors." This purpose has unquestionably been amply fulfilled in these brief, lucid, and relatively elementary presentations of more or less every-day problems in cardiovascular disease. The book offers instructive and entertaining reading and should prove popular with those who like to supplement their intellectual diet with an apple a day from the tree of knowledge. ARTHUR J.
