INTRODUCTION, 7 
Salvin’s fourth and last visit * to Guatemala was made in conipany with his wife, to 
whose skilful brush we are indebted for the coloured plates of the plants figured in the 
Botany of the ‘ Biologia.’ 
They sailed in a Royal Mail Steamer in April 1873, touching at St. Thomas and 
Jamaica; then crossing the Isthmus of Panama they reached the City of Guatemala early 
in June. Proceeding thence to Duefias, which became their headquarters for some 
months, Salvin occupied himself in collecting in the forests on the mountain slopes. 
Together they ascended the crater of the Volcan de Fuego, and a few days later that 
of Acatenango. Leaving Duefias for Atitlan they made the ascent of the peak from 
Santa Lucia on Jan. 17th. Subsequently they visited Mazatenango, the coffee estate 
of Las Nubes (Cerro Zunil), Quezaltenango, the Lake of Atitlan, Solola, Pantaleon, and 
San Gerdnimo, and after a short stay at the last named place the journey was continued 
to Coban. Having revisited the Capital they left Guatemala in March 1874. Again 
erossing the Isthmus of Panama, they sailed for the United States and visited the 
museums of New York, Boston, Philadelphia, and Washington, and made the acquain- 
tance of the leading scientific people, returning to England on June 4th, 1875. 
In the autumn of the same year, Salvin was appointed to the Curatorship of the 
Strickland Collection of Birds at Cambridge, which necessitated his residence at the 
University. On his giving up the house in South Kensington in 1873, it had become 
necessary to find fresh quarters for our museum and library, which now occupied a 
considerable amount of space, and we took for this purpose a house in Tenterden 
Street, Hanover Square, to which they were transferred. ‘The building being rather 
larger than we required, we shared it with some of our ornithological friends, of whom 
Lord Lilford, Dresser, and Seebohm were among the number. After the evening 
scientific meetings of the Zoological Society, the offices of which were then in Hanover 
Square, our rooms became a favourite social resort of ornithologists, and many 
pleasant and instructive hours were spent there. 
During his stay at Cambridge, Salvin came frequently to Tenterden Street and 
worked at the collections with me, and continued so doing until the death of his father 
in 1880, when he succeeded to his property at Fernhurst, Sussex, where he afterwards 
resided, continuing, however, his work in London as before. In the autumn of 1878 
we moved our museum and library to 10 Chandos Street, Cavendish Square, and 
here they remained till after Salvin’s death. In 1907 the house at Chandos Street 
was given up and the library transferred to 45 Pont Street, S.W., while the collections 
still remaining in our possession were handed over to the British Museum. 
In addition to the material obtained during our various visits to Central America 
and that sent us by the natives we had trained, we found it necessary, for the sake of 
comparison, to acquire a more thorough knowledge of the South American fauna, and, 
* In the notice of his journeys given in the Introduction to the ‘ Aves’ (p. vili) the second expedition, 
1859-1860, was not mentioned, and the last visit was incorrectly stated to have been made in 1867.
