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 Phaenoga- 

 mous botany ; and in his favorite department of the science 

 he had brought out, in 1841, his " Manual of British Algae," 

 which he reedited 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 Algae 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 

 Irish 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-
