WILLIAM HENRY HARVEY. 339 
He had already published, at the Cape, in 1838, his “ Ge- 
nera of South African Plants,” hastily prepared, solely for 
local use, but no unworthy beginning of his work in Phenoga- 
mous botany; and in his favorite department of the science 
he had brought out, in 1841, his “ Manual of British Alge,” 
which he reédited in 1849. He now commenced the first of 
the series of his greatest works, illustrated by his facile 
pencil, for he drew admirably. The first (monthly) part of 
his excellent and beautiful ‘“ Phycologia Britannica, a History 
of British Seaweeds,” containing colored figures of all the 
species inhabiting the shores of the British Islands, appeared 
in January, 1846; and the undertaking was completed in 
1851 in three (or four) volumes, with three hundred and sixty 
plates, all drawn on stone by his own hand. A similar but 
less extended work, the “ Nereis Australis, or Algz of the 
Southern Ocean,” which was begun in 1847, was carried only 
to fifty plates of selected and beautiful species. 
In 1848, Dr. Harvey succeeded Dr. Litton as professor of 
botany in the Royal Dublin Society, to which belonged the 
botanic garden at Glasnevin; this required him to deliver 
short courses of lectures annually in Dublin or some other 
Trish town, and provided a welcome addition to his income. 
In 1848, at the request of his friend Van Voorst, the pub- 
lisher, he wrote his charming little volume, “ The Seaside 
Book,” the unsurpassed model of that class of popular scien- 
tific books ; it was published in 1849, and has passed through 
several editions. In July of that year, having arranged a 
visit to this country, and having been invited to deliver a 
course of lectures before the Lowell Institute, he took steamer 
for Halifax and Boston, passed the summer and autumn in 
exploring the shores of the northern States, and in the society 
of his friends and relatives ; for the late Mr. Jacob Harvey, 
still well and pleasantly remembered in New York, who 
married the daughter of Dr. Hosack, was his elder brother. 
In the autumn he gave an admirable course of lectures upon 
Cryptogamic botany before the Lowell Institute in Boston, 
and afterwards a shorter course at the Smithsonian Institu- 
tion at Washington. He then traveled in the southern At-
