George Roddam, Esq., M.D., a naval physician of much skill 

 and eminence, was attached to natural history, and made collec- 

 tions in several of its departments, especially entomology. He 

 entered the Navy in 1797 as Surgeon of H.M.S. Thorn, on the 

 Leeward Island Station, and continued to serve in various ships of 

 war until 1812, when he was appointed Surgeon of the Royal 

 Charlotte yacht. From this time his services were confined to the 

 Royal yachts, and he finally retired from active service in 1831. He 

 was elected a Fellow of the Linnean Society in 1813, and died on 

 the 11th of October 1838. 



Thomas Taylor, Esq., M.D., the. coadjutor of Sir W. J. Hooker in 

 the 1st and 2nd editions of ' Muscologia Britannica,' was possessed 

 of a moderate independent income, which obviated the necessity of 

 his devoting himself to the practice of his profession, and was thus 

 enabled to follow the bent of his inclination, and to make botany, 

 and especially cryptogamic botany, the business of his life. He re- 

 sided chiefly in the South of Ireland, and during the existence of 

 the Royal Cork Scientific Institution, occupied the chair of Botany 

 and Natural History in that establishment ; but afterwards retired to 

 Dunkerron, Kenmare, in the immediate neighbourhood of the lakes 

 of Killarney, where the latter years of his life were passed in studious 

 retirement. T\\&Musci, Hepatica and Licheties formed the principal 

 subjects of his study. His intimate knowledge of the first was tes- 

 tified by his contributions to the ' Muscologia Britannica ;' an im- 

 portant memoir on the Marchantiece, published in the 17th volume 

 of our 'Transactions,' evidences his profound acquaintance with the 

 Hepaticae; and several contributions to SirW. J. Hooker's various 

 periodical publications, show that he had paid great attention to the 

 very difficult family of Lichens. He also contributed largely to the 

 Cryptogamic portion of Dr. J. D. Hooker's ' Flora Antarctica ;' of the 

 Hepaticee and Lichenes of which work a Synopsis was given in the 

 3rd volume of Hooker's ' London Journal of Botany,' together with 

 a Supplement to the Hepaticce in vol. iv. 



Dr. Taylor is described by those who were most familiarly ac- 

 quainted with him, as possessing a mind well-stored in various 

 branches of science and literature, while his gentle and amiable 

 manner rendered him a great favourite with all who had the happi- 

 ness of his acquaintance. He became a Fellow of the Linnean So-
