Panama; but Mr. Salvin tells me that Dr. M. B. Halsted had charge of the foreign 

 hospital at Panama probably during the construction of the Railway, and that he met 

 Dr. Halsted, he believes, in 1859, in Guatemala, where he resided at Antigua, and where 

 he died shortly after. William Lobb, collector for Messrs. Veitch of Chelsea, spent 

 some months in the neighbourhood of Panama and Chagres in 1843, but he appears to 

 have dried very few plants. 



K P. Johnson. — A small collection of plants made in Yucatan and Tabasco by the 

 Honourable E. P. Johnson was presented to Kew by Dr. Torrey in 1850, and merits 

 notice here on account of the little we know of the botany of this part. 



Frederick Mueller. — An Alsatian who went to Mexico in 1853, at the cost of Mr. 

 Schlumberger of Mulhouse, and collected largely between Vera Cruz and Orizaba. It 

 is supposed that he was murdered and concealed, as he disappeared and was never 

 heard of afterwards. There is a good set of his plants in the Kew Herbarium. 



Ludwig Safin, who lived for nearly twenty years in Mexico as a teacher of music, 

 was a zealous collector of plants and animals, and sent numerous consignments of 

 both to Europe and especially to the Berlin Botanic Garden. Several new species of 

 the curious genus Wolffia (Lemnaceee) are among his most remarkable discoveries. He 

 was attached to the French Scientific Commission with Bourgeau, and died in Mexico 

 in 1873. A small set of his plants is at Kew. 



Carl Hoffmann and Alexander von Frantzius. — These gentlemen left Europe for 

 Costa Rica in 1853 for the purpose of investigating the natural history and geography 

 of the country *, where they spent several years. Dr, Hoffmann wrote several inter- 

 esting papers on the vegetation &c. of Costa Rica, notably an account of the ascent 

 of the Volcan de Cartago and the Volcan de Barb a, references to which are given in 

 our Bibliography. A very few of his plants are in the Kew Herbarium. 



Hermann Wendland, Court Gardener at Herrenhausen, Hanover, w 7 ent out to 

 Central America towards the end of 1856, and spent eight months in Costa Rica and 

 Nicaragua, chiefly occupied in collecting living plants, among which were many new 

 orchids f . This gentleman is one of the first recognized authorities on Palms. 



Wilhelm Schaffher. — A pharmaceutical chemist, native of Darmstadt, who settled 

 in Mexico previous to 1856, in which year the late Sir William Hooker received 

 from him the first collection of dried plants J. From time to time further contribu-
