THE ORCHID REVIEW. 363 
mostly new. The drought in the interior rendered it impossible to pro- 
ceed by that route to St. Salvador, and I accordingly embarked for that 
place in a canoe, and arrived ineight days. Here I found the two Prussian 
naturalists, Messrs. Sellow and Freyries, who had come overland from Rio 
de Janeiro with the Prince of Neuwied, and had remained in the city from 
ill health, and also to arrange their collections. I left them, however, soon, 
and made nearly a complete tour of the bay, and again set out for the 
Sertem or inland country, where I continued, varying my residence, until 
the month of March following, having in this space made immense collec- 
tions in every branch of natural history, particularly in the ornithology of 
the interior, which differs both in species and novelty from those procured 
by the Prussian travellers on the coast. 
“In the month of April I embarked for Rio de Janeiro, more for the 
sake of comparing the southern with the equinoctial regions of Brazil, than 
of increasing my collections in a part already well explored. I found the 
summer nearly terminated, but the heat far above that of Pernambuco, 
though Rio de Janeiro is in lat. 22° 54’, and Pernambuco in lat. 8°. 
Travellers and men of science from the Austrian, French, Russian, and 
Tuscan Courts were here. Few of them, however, had been out of the 
province, and, by some unfortunate mismanagement, five of the Austrian 
party returned home shortly after my arrival. Among these travellers was 
Professor Raddi, director of the museum at Florence, who was indefatigable 
in forming a fine collection of the fruit and seeds of the country. With him 
I made an excursion to the immense range of mountains, called the Organ 
Mountains, which for leagues are covered with almost impenetrable forests, 
abounding in ferns, melastomas, and insects quite peculiar to them. From 
Dr. Langsdorff, the Russian Consul-General in Brazil, I received every 
assistance and the most liberal attention ; and having with his aid embarked 
my collection, with many desiderata, I returned to England in August, 
1818. ‘ 
“ Seeds of many new and little-known plants have been sent to Kew 
and other botanic gardens, where they are now flourishing. An interesting 
collection of parasitic plants, together with another of cryptogamia, I pre- 
sented to my friend W. J. Hooker, Esq. These last have begun to appear 
in his elaborate work Musci Exotici. My herbarium, containing about 
1,200 species, is particularly well preserved, the plants having been dried 
by a new process which will enable a botanist in a tropical climate to dry 
nearly 400 specimens in three days. It is very rich in ferns and grasses, as 
well as other genera little known as natives of the tropics. 
“I have, besides, a portfolio of drawings representing the most striking 
Picturesque and vegetable scenery, together with maps of the different routes 
pursued,.”’—Edin. Phil. Fourn. i., pp. 369-373-
