Or an increase of 1 per cent of humidity has as much influence on 
the condition of an air-space (as judged of by the sense of smell) 
asarise of 4°18 of temperature in Fahrenheit’s scale, equal to 
2°32 Centigrade, or 1°-86 Reaumur. 
' This may be taken as a proof of the powerful influence exercised 
by a damp atmosphere, corroborating the conclusions arrived at 
by ordinary experience; and it follows that as much care ought 
to be taken to ensure proper hygrometric conditions as to maintain 
a sufficiently high temperature. This is especially the case in the 
wards or chambers of the sick, in which regular observations with 
the wet and dry-bulb thermometers ought to be made; these would

largest of which is the collection from Peru and Bolivia, made by 
Mr. Alexander Agassiz and Mr. §. W. Garman, during their 
journey in South America. This collection, obtained at a large

articles of clothing, balls of thread, spindles, and other articles 
ected with weaving, “which art was developed to a very high 
state by the ancient Peruvians;” also work boxes, ornaments
