This monograph contains a complete summary of the recent work done on total thyroidectomy in heart disease. No new material is presented, but the author has given an excellent presentation of the development of this new surgical procedure of American origin. To the reader in this country the book is superfluous, since the subject has been summarized many times in the various communications of Blumgart, Levine and others. The appearance of the monograph at this time illustrates the lag in enthusiasm for new procedures in different countries. In this country the operation is on the wane, but apparently in France the peak has not yet been reached.
