Abstract
AS was to be expected in a work on human rather than comparative embryology, the second edition of Prof. Dodds's text-book, which is intended mainly for medical students, does not differ greatly from the first, published nine years earlier. Many of the chapters are little if at all altered, but there are certain sections in which changes have been introduced as a result of recent researches. These relate more particularly to the early stages of development, the testis and ovary, the placenta, the ages of embryos, the formation of bone, the pharynx and its derivatives, the blood vessels, and the growth of nerve fibres. Moreover, the chapter on ovulation, menstruation, and pregnancy has been almost entirely rewritten.
