Botany and Zoology. 277 
Dr. Harvey was one of the few botanists of our aye who excelled both 
in phenogamie and cryptogamic botany. In Algology, his favorite 
branch, probably he has wie? no superior ; in systematic botany generally 
he had now an —— position. He was a keen observer and a capital 
describer. He in cosa accurately, worked readily and easily with 
microscope, pencil aa pen, wrote perspicuously, and where the subject 
permitted, with captivat inet grace ; affording, in his lighter productions 
mere glimpses of the w and poetical imagination, delicate humor, 
refined feeling, and sincere hacia which were charmingly revealed ie 
intimate intercourse and correspondence, and which won the admiration 
and the love of all who knew him well. Handsome in person, gentle 
and fascinating in manners, genial and warm-hearted but of very retiring 
ma a simple in his tastes and unaffectedly devout, it is not surpris- 
ing that he attracted friends wherever he went, so ie his death will be 
sensibly felt on every continent and in the islands of the sea. A. G.
