ent ranges of temperature in the Provinces adjacent to the United

ston SOCIETY or NATURAL History. March 6,1867.—Dr. J. C. 
White exhibited a specimen of Guaranà, moulded into the form of the 
Jararaca, the most poisonous of Brazilian serpents; it was brought 
from Brazil by Mrs. Agassiz, and was presented to the Socicty by Dr. 
Cotting. The Guarana is made from the seeds of the Paullinia sor- 
bilis, which are roasted, ground, mixed with water, moulded, 
dried hard in an oven. It contains a larger quantity of cafline than 
either tea or coffee, and resembles in appearance common chocolate; 
dissolved in water it is used as a refreshing drink, and as a remedy 
for fevers and other ailments. The Manés Indians, who manufacture 
it, believe it to be more efficacious when made into the form of a ser- 
pent, as in the specimen exhibited. 
Dr. T. M. Br rewer ATM upon the Wood-warblers of North 
America, a group of birds which unite in a remarkable degree the hab- 
its of the tree-creepers with those of the fly-catchers. In some species 
these habits are alternated as occasion seems to prompt. Some are 
almost entirely creepers, others almost exclusively fly-catchers. The 
yellow red-poll warbler is the only one of this group which is known 
to breed upon the ground, or to be at all terrestrial in habit, by 
choice; when occasion offers it can be an expert fly-catcher, but when 
seeking its food on the ground its motion is graceful and easy, show- 
ing that the habit is native to the bird, and not assumed by the 
prompting of necessity.
