stitute, and had given much labor to the investigation of the his- 
tory of his nativet own (Byberry), and to the study of his family 
genealogy. 
It is remarkable that a man burdened with such exacting and 
responsible business cares, should have been able to accomplish 
so much in what were to him mere avocations, and botanists can- 
not help recalling the similar instances of Dr. Wm. Darlington 
and David Townsend, of West Chester, Pa., both bank officers, 
and both most ardent and successful botanists. And yet it is to 
be feared that Mr. Martindale overtaxed his strength, and perhaps 
had he shortened his hours of labor he might have been spared 
to the world for many years longer. Symptoms of failing health 
had led him to resign his position, within a week or two before 
his death, in order that he might find resoration by travel, and he 
had intended a visit to South America.

Anatomy as a Special Department of Botany.” 
By EmiLty L. GREGORY. 
The question of the exact limitation and relative importance 
of the various departments of botany is by no means a simple one. 
To verify this assertion it is necessary only to consider briefly the 
definitions given by some of the best writers of botanical text 
books. In our own country there is perhaps no higher authority 
than that of Asa Gray, who in his text book of 1857 says: Physi- 
ology is the study of the way a living being lives and grows and 
performs its various operations. The study of plants in this view 
is the province of Vegetable Physiology. The study of the form 
and structure of the organs or parts of the vegetable by which its 
operations are performed, is the province of Structural Botany. 
The two together constitute Physiological Botany,” &c. The title 
page of the same book is headed “ Gray’s Lessons in Botany and 
Vegetable Physiology,” and again in the text we find “ Botany is 
the name of the science of the vegetable kingdom in general.”
