LETOEAN SOCIETY OF LOKDON, Ixiii 



" In July, 1840, lie sailed for tlie third time for the Cape of 

 Grood Hope, where intense application and oyer-exertion in bota- 

 nical pursuits again brought on severe disease, and he was com- 

 pelled to return to England in 1841, and ultimately to resign his 

 colonial appointment. 



"After this he appears to have spent a short time in his brother's 

 house of business ; but mercantile pursuits had never any charm 

 for him, and in 1843 he became a candidate for the post of Keeper 

 of the Herbarium of Trinity College, Dublin, vacant by the death 

 of Coulter, the Cahfornian and Mexican traveller ; Harvey offering 

 at the same time his beautiful herbarium, consisting of upwards 

 of 10,000 species, to the College. The Professorship of Botany 

 fell vacant at the same time, and the College having determnied 

 to unite the two offices, Harvey became a candidate for both, and 

 in spite of powerful opposition, and the fact that a medical degree 

 of the College was a sine qtoa non, he all but carried the day, the 

 CoUege having given him the honorary degree of M.D. to obviate 

 this latter objection. After a good deal of debate it was at last 

 settled that the Professorship should be separate from the Cura- 

 torship, the former being given to Dr. Allman, the present distin- 

 guished Professor of Natural History in Edinburgh, and the Cura- 

 torship to Dr. Harvey, with a salary of £150 per annum and 

 rooms, an arrangement that perfectly satisfied, and indeed, as he 

 said himself, pleased him. 



" From this time forth his whole energies were devoted to the 

 prosecution of botanical science. "With characteristic conscien- 

 tiousness he first set himself to arrange and distribute to scientific 

 museums the collections of his predecessor, to arrange the herba- 

 rium, and make all ready for the furtherance of science. For 

 several subsequent years he devoted himself chiefly to Algse, and 

 latterly, at the urgent desire of his friends at Kew, he undertook 

 the ' Flora Capensis,' which occupied most of the latter years of 

 his life. 



" In 1847 he became a candidate for, and obtained, the Pro- 

 fessorship of Botany in the Eoyal Dublin Society, vacant by the 

 death of Dr. Litton, to whose modest merits he paid the kindly 

 tribute of dedicating the beautiful South African plant, Littonia 

 modesta. This office he continued to hold during his life under 

 its correlative Institution the Museum of Irish Industry, subject 

 to the direction of the Science and Art Department of the Com- 

 mittee of Privy Council on Education. 



" In the year 1849 he received a joint invitation from the Smith-
