    TO THE SECOND EDITION. The friendly reception which the Text-book of the Embryology of Man and Mammals has found, is an indication of the increased interest which this branch of Morphology now meets with. Even more than a year ago, after the fii-st part of the text-book appeared and while the second part was in the press, the necessity of 23reparing a second edition became evident. In this edition fundamental changes have not been undertaken; the text has, however, undei-gone an expansion in some places, owing to the attention given to several works which have recently appeared. This has been the case with the section on the first developmental processes of the egg (Weismann, Blochmann) ; that on the origin of the vascular system (Rabl, Ruckert) ; that on the development of the fffital membranes (Duval, Osborn) ; and that on the human placenta (Kastschenko, Waldeyeb, Ruge). As the second part of the text-book has just appeared, it has been possible to incorporate it in the second edition without alteration. It has, furthermore, seemed to me expedient in the second edition to distribute at the ends of the several chapters the synopses of the literature, which in the first edition were brought together at the close of the whole work. Finally, there has been added an index of subjects, by which a more I'apid oz'ientation concerning the separate topics will be facilitated; this will increase the usefulness of the work. May the book in this form make for itself new friends, not only among students of medicine and the natural sciences, but also with all those who have a fondness for and a comprehension of studies in natural science.
