BIOLOGISTS.

William Henry Harvey (b. Limerick 1814, d. 1866), F.R.S., was a
botanist of very great distinction. During a lengthy residence in
South Africa, he made a careful study of the flora of the Cape of
Good Hope and published _The Genera of South African Plants_. After
this he was made keeper of the Herbarium, Trinity College, Dublin,
but, obtaining leave of absence, travelled in North and South
America, exploring the coast from Halifax to the Keys of Florida, in
order to collect materials for his great work, _Nereis
Boreali-Americana_, published by the Smithsonian Institution.
Subsequently he visited Ceylon, Australia, Tasmania, New Zealand, and
the Friendly and Fiji Islands, collecting algae. The results were
published in his _Phycologia Australis_. At the time of his death he
was engaged on his _Flora Capensis_, and was generally considered the
first authority on algae in the world.
