Abstract

THE great interest taken at the present time in the subjects included under the comprehensive term “genetics” is illustrated by the fact that second or later editions of three standard works in German on the subject, each consisting of more than 500 pages, were published in 1913. It is inevitable that books of this kind should overlap to some extent, but they do so much less than their titles might lead one to expect. That they are so different is due partly to the great extent of the subject, which makes it possible for books to deal with different sides ot it without encroach ing on one another to any great extent, and partly to the wide differences of opinion which still exist, resulting in very different treatment of similar classes of facts.
