Ayres. With this view, Mr. Burchell left England in 
March, 1825, passed two months at Lisbon and its vicinity, 
and landed, in July, at Rio de Janeiro, which he did not 
finally quit till September, 1826. During that period, he 
collected largely in Botany, Entomology, Geology, &c.: 
made astronomical, philosophical and geodetical observa- 
tions, together with several drawings of the country, and, 
among others, a panoramic view, taken from the middle of 
the city; he also visited a part of Minas Geraes. From Rio, 
Mr. Burchell proceeded by sea to Santos, where he remained 
three months, exploring the neighbouring districts. Cubatao 
was his next station, in a solitary hut in the midst of forests, 
with a view to investigate the productions of the great range 
of mountains, at the foot of which it stands, and to examine 
the chain at his leisure: there he remained two months. At 
the city of San Paulo, nearly under the tropic of Capricorn, 
our enterprising Naturalist found abundant employment for 
seven months, making that place his head-quarters, and ex- 
' tending his researches in various directions from thence. 
There “Mr. Burchell engaged muleteers and purchased 
mules; and, travelling northwards, finally fixed himself for 
nine months at Goyaz, being the first Englishman that had 
entered that province: there, too, he passed the rainy season 
of 1827, and made large collections, partly detained by the 
difficulty of procuring conveyance for bis luggage. In a 
letter we had the gratification of receiving from him, dated 
Goyaz, April 25th, 1828, he says, “I have now for five 
months carried on a series of observations. The Botanical 
part of my collection already includes more than 5000 
species, and the last number of my American Catalogus 
Geographicus is 7063. The Entomological portion is eight or 
nine times as large as my African collection was; and all the 
other departments are considerable, excepting the Mammalia 
and Fishes ; and if I am equally successful on the road between 
this place and Para, I may yet add two or three thousand more 
Species to my herbarium; and to the other parts in proportion. 
Although my progress over this Continent has not been rapid, 
yet I have kept my original plan always in view, and had
