evidence is trustworthy. 
e statements we have quoted give satisfactory proof that 
different kinds of plants may live in water of various temper 
atures, as high as 168° F., as observed by Dr. Hooker in Sor- 
ujkund, 174° as observed by Capt. Strachey in Thibet, 185° as 
observed by Humboldt in La Trinchera, 199° as observed by 
Dr. Brewer in California, and 208° as observed by Descloizeaux 
in Iceland. The lowest forms only are found in the hottest 
aters. 
With regard to animals the testimony is much less complete. 
The highest temperature at which they have been found, in 90 
far as we have seen any evidence was, as stated by Major Long, 
150° F., in the hot springs of the Ouachita where he found “br- 
valve testaceous animals” and insects. In the instance men 
whether their bodies were as hot. They are air-breathing anr 
mals, but it is not unlikely that the heat of their bodies is kept 
down as in others whose breathing is aerial by the evaporation 
from their respiratory and other surfaces. Otherwise it does not 
appear how the albuminous matter in their fluids is kept from 
coagulation. When walking on the surface of the water 1618
