acquired some knowledge of Arabic, -which enabled him to converse freelj with 
the natires, and acquire much information ■which is inaccessible to traTellers 
who do not possess similar advantages. In early life he communicated to the 
* Medical Gazette ' a series of papers on the diseases peculiar to the Aboriginal 
tribes of the Bights of Biafra and Benin, which he afterwards revised and ex- 
tended for publication in a separate form under the title of * Sketches of the 
Medical Topography and Native Diseases of the Gulf of Guinea, Western 
Africa,' London, 8vo, 1819. He afterwards became a frequent contributor 
to the ' Journal and Transactions of the Pharmaceutical Society of London,' 
and the following list of his papers will show how extensive was his acquaint- 
ance with the useful and medicinal plants of Western Africa in particular, with 
their chemical composition, and with their economical and therapeutic uses : —

in vol. ix. 2. " On the Synsepahim duJciJiciim^ or Miraculous Berry of Western

Journal,' March, 1865. Dr. Daniell was engaged during his last illness in writing 
this paper, part of which still remains unpublished. He had made the important 
discovery that Theine existed in the Kola-nut, and he had the satisfaction to find 
his discovery established by the analysis of the nut, made at liis request, by Dr. 
Attiieid. The Copal-tree referred to in one of these papers has been described 
by Mr. Bennett as a new genus, under the name of G«/5oHr^zfl!, and the Frank- 
incense-tree under that of Daniellia. The latter is a strikingly distinct genua, and 
worthily commemorates the botanical merits of its discoverer, after whom Mr. 
Bennett has also called a remarkable species of Pkrt/niumy with a dcliciously 
sweet and succulent fruit, P. DaniellL On his return from the Chinese Expe- 
dition, Dr. Daniell brought with hira from Manchouria specimens of several 
species of oaks, which have been described by Mr. Carruthers in the sixth 
volume of the ' Journal of the Linnean Society.' Many of the specimens which 
he collected are in the Herbarium of the British Museum, to wliieh he waa a 
frequent and liberal contributor. As may be judged from the nature of his
