OPINIONS OF THE PRESS.
“The Columbia University of New York has decided to issue a series of small volumes on Biology, under the editorship of Dr. Osborn, the Da Costa Professor of Biology. It is not to be a library of elementary text-books in the ordinary sense of the term, but to consist chiefly of works dealing with certain fundamental problems which will concern students who have passed beyond preliminaries.”—Natural Science (London).
