260 BOTANICAL INFORMATION, 
fact, that on the elevated regions of the Andes, this Order 
forms nearly one-third of the whole vegetation. 
You will doubtless be pleased with my Pozoa hydrocotyli- 
folia (marked 1,190 of the Catalogue); but I beg you will 
only adopt this name if previously unappropriated. I think 
it will be found worthy to figure in your Botanical works, as 
it is quite distinct in habitat and characters from the other 
species. It only grows in dry, stony, sandy places in the 
bed of the mountain-rivers on the eastern side; while P. 
coriacea inhabits rocky spots on the western slope of “ Los 
Impossibles," at the verge of the snow. 
Besides plants, I forwarded for sale a small set of Birds 
from the Andes. "There were five sp. of Fringilla, some re- 
markable for the sweetness of their note; a most singular 
bird, allied to the genus Anas, having spurs on its wings, 
and which ascends the Rapids in a truly astonishing manner; 
also an elegant Picus, called by the natives “ Carpintero de la 
Cordillera,” and * Concona.” Together with these, I sent a 
few Coleopterous Insects from the valleys of the Andes; and 
hope next year to obtain the rare Chiosagnathus Grantii from 
the south of Chili. 
During my rambles over the Andes, aud while staying in 
the valleys, I kept a rough Journal, in which I entered my 
observations on the local distribution of vegetation, and some 
remarks on the movement of the thermometer; but a con- 
sciousness of my deficiences, together with natural timidity, 
have hitherto hindered me from preparing it for the public 
eye, or even transmitting it home. Had I done so, it is pro- 
bable that your kind aid would have brought it into a form 
worthy of one of the Journals: and it certainly contained 
many details, as to the habitats of interesting plants and 
birds, with much information both botanical and ornitholo- 
gi I also brought down a few specimens of primitive 
rocks that might have pleased a geologist. My Journal 
would have shown somewhat of what the traveller has to en- 
dure, when spending a month at an elevation of from 10,000 
to 12,000 feet. As to myself, I enjoyed perfect health, and
