170 HORACE MANN. 
appointed Dr. Gray's assistant, and afterwards Instruetor in Botany in 
Harvard College. Besides the work of arranging the Thayer Herba- 
rium and constantly aiding Dr. Gray in preparing material for his 
classes, and revising proofs of his two botanical manuals,—a work 
more than enough for a common man, a work indeed that no common 
man could do,—he worked steadily in his spare hours, often late into 
the night, on his Hawaiian collections. The many thousand specimens 
were determined and labelled and partly distributed; his * Enumera- 
tion of Hawaiian Plants,’ which has given him a good botanical repu- 
giis was published by the American Academy of Arts and Sciences 
(of w e was unanimously elected a Fellow on the very evening of 
his nee ; a most complete Flora of the islands was published in 
part by the Essex Institute; several other botanical memoirs were in 
hand, and you all know that his labour here in our herbarium and in 
our work as a Society, was not light. 
His interest in this Society never waned. Often on shipboard, lying 
on deck at night, have we talked over this matter, and he was full of 
suggestions, many of which have since been carried out; others, such 
as a permanent doorkeeper for the Museum on exhibition days, guide- 
books to the various collections, and a fire-proof floor for the main story 
of this building, will be perhaps in time. He was always present at 
the Council meetings, and his advice was always sensible and re- 
spected. 
As a result of our Hawaiian explorations, five new genera were 
added to the flora, one of which was dedicated to him under the name 
of Hesperomannia, and has been engraved for the next part of our 
Memoirs, while of new species of flowering plants, no less than seventy- 
one, or more than eleven per cent. of the entire pheenogamous Hawaiian 
flora were discovered. His published works, besides a number of re- 
views in the * American Naturalist,’ were :— 
‘On some Hawaiian Crania and Bones.’ (Proc. Bost. Soc. Nat. Hist. 
vol. x. p. 229.) 
‘On the present condition of Kilauéa and Mad Lda.’ (Ibid. vol. x. 
) 
" es on the Hawaiian Islands.’ (Ibid. vol. x. p. 232. 
‘Revision of the Genus Schiedea and some of the Rutacee.’ (Ibid. 
vol. x. p. 309.) 
‘Description of the Crater of Haleakala.’ (Ibid. vol. xi. p. 112.)
