APPEN-DIX TO

THE AMERICAN NATURALIST,

JUTLY, 1873.

ON PROFESSOR MARSH'S CRITICISMS.

THE recklessness of assertion, the erroneousness of statement, and the incapacity of comprehending our relative positions, on the part of Professor Marsh, render further discussion of the trivial matters -upon which we disagree unnecessary; and my time is too fully occupied on more important subjects to permit me to waste it upon personal affairs which are already sufficiently before the public. Professor M. has recorded his views " cgre perenne," and may continue to do so without personal notice by E. D. COPE.
