peptone and other products of digestion can not be detected, in any quantity, at least, in the blood of the portal vein, even after the ingestion of a diet rich in proteids. As has been frequently stated in the past, the products of proteolytic action are transformed in the very act of absorption, presumably through the activity of the epithelial cells of the villi, and we may now assume, in the light of Pohl’s results, that this transformation may be due in part, at least, to the upbuilding of the ordinary products of digestion into the living protoplasm of the white corpuscles in the intestinal walls, and in this form as organized albumin circulated through the body. Editorial in Dietetic and Hygienic Gazette, November, 1893. Book Notices. AN AMERICAN TEXT-BOOK OF GYNECOLOGY, MEDICAL AND SURGICAL, FOR THE USE OF STUDENTS AND PRACTITIONERS. Edited by J. M.

(Sold by Subscriptions only; Price, $6.00). The magnificent work described above has just been received from the publisher, and inasmuch as it is at once the most modern and most complete of all works of this class prepared exclusively by American authors, it will naturally receive a warm welcome. A somewhat cursory examination shows that it is what it claims to be, namely, a practical work, written by practical men, who are, themselves well qualified by experience, and thoroughly equipped for teaching, all being teachers in high repute in different medical schools. Owing to this special feature, it is entitled to more than usual attention at the hands of American physicians; but this characteristic will give it standing abroad, and doubtless will be the means of advancing the cause of scientific treatment in the class of cases with which it has to deal. Theory and speculation have been set aside, and in their place we find reliable data not alone for the operator, but also for the general practitioner, and we bespeak for the work a favorable reception. The following extract from the prospectus will give in brief the main objects kept in view in its preparation: In this volume all anatomical descriptions excepting what is essential to a clear understanding of the text have been omitted, illustrations being largely depended upon to elucidate this point. It will be found thoroughly practical in its teachings, and is intended, as its title implies, to be a working text-book for physicians and students. A clear line of treatment has been laid down in every case, and, although no attempt has been made to discuss mooted points, still the most important of these have been noted and explained; and the operations recommended are fully illustrated, so that the reader may have a picture of the procedure described in the text under his eye, and cannot fail to grasp the idea.
