Bates, Henry Walter (1825-92): was born at Leicester, and after an
apprenticeship in a hosiery business he became a clerk in Allsopp's
brewery. He did not remain long in this uncongenial position, for in 1848
he embarked for Para with Mr. Wallace, whose acquaintance he had made at
Leicester some years previously. Mr. Wallace left Brazil after four years'
sojourn, and Bates remained for seven more years. He suffered much ill-
health and privation, but in spite of adverse circumstances he worked
unceasingly: witness the fact that his collection of insects numbered
14,000 specimens. He became Assistant Secretary to the Royal Geographical
Society in 1864, a post which he filled up to the time of his death in
1892. In Mr. Clodd's interesting memoir prefixed to his edition of the
"Naturalist on the Amazons," 1892, the editor pays a warm and well-weighed
tribute to Mr. Bates's honourable and lovable personal character. See also
