WEISMANN, Professor in the University of Freiburg-in-Breisgau. With 24 Illustrations.

“There has been no work published since Darwin’s own books which has so thoroughly handled the matter treated by him, or has done so much to place in order and clearness the immense complexity of the factors of heredity, or, lastly, has brought to light so many new facts and considerations bearing on the subject.”--_British Medical Journal._
