Notwithstanding his feeble bodily constitution, Professor Henfrey's 

 labours were incessant. Whilst constantly engaged in original in- 

 vestigations, the results of which he made known in various papers 

 which appeared in the * Transactions ' of the Royal and Linnean 

 Societies, the t Annals and Magazine of Natural History,' and the 

 'Journal of the Agricultural Society/ his untiring industry also 

 enabled him to furnish numerous translations and abstracts of 

 foreign memoirs to the Natural History Journals, and to give 

 reviews and critical notices of botanical works in these periodicals, 

 as well as in the 'Quarterly Review. 5 Moreover, he translated 

 several independent works from the French and German languages, 

 and composed some valuable elementary treatises on botanical sub- 

 jects, of which his 'Elementary Course of Botany/ published in 

 1857, is the last and most important. For three years also he con- 

 ducted the 'Journal of the Photographic Society/ and since 1858 

 was one of the most active editors of the new series of the ' Annals 

 of Natural History/ 



Professor Henfrey was a man of an amiable and gentle nature, 

 which neither the pressure of daily toil nor the trying interruption 

 of ill-health could ever ruffle : his death, on the 7th of September, 

 1859, at the early age of thirty-nine, hastened as it probably was by 

 his unremitting exertions, has been deeply lamented by all who knew 

 him. 



THOMAS HORSFIELD, M.D., was born at Bethlehem, in Penn- 

 sylvania, on the 12th of May, 1773, of parents who were Moravians, 

 in which Christian communion he lived and died. He was educated 

 for the medical profession in the University of Pennsylvania, where 

 he took the degree of Doctor of Medicine in 1798. Early in life he 

 went to Java, where he passed sixteen years, actively engaged in the 

 pursuit of Natural History, to which he had devoted himself. During 

 his residence in Java, he thoroughly explored every part of the 

 island, in quest of its natural productions. From Java he visited 

 Banca, and gave the fullest and best account which exists of that 

 island. After the restoration of Java to the Dutch in 1816, Dr. 

 Horsfield made a long sojourn in Sumatra, and there continued his 

 favourite studies ; but having made the friendship of Sir Stamford 

 Raffles, who is said to have imbibed from Horsfield his well-known
