PREFATORY NOTE.

Mr. V. A. Clark, as a student in horticulture in the University
of Vermont, first undertook a critical examination of Naegeli's
_Mechanico-Physiological Theory of Evolution_ as a part of his regular
junior work. After a half year's study and the preparation of a short
thesis, Mr. Clark had become so far intimate with Naegeli's work as to
