J. Wyman on living organisms in heated water. 157 
Dr. Carpenter in his General and Comparative Physiolog 
mentions several instances of animals living in a high temper- 
ature and also states, that “at the island of New Amsterdam 
there is a mud spring, which, though hotter than boiling water, 
gives birth to a species of Liverwort.”* It is presumed that this 
is the island of the same name referred to by Humboldt, but 
he only states. that the springs in question were much hotter 
than those ef the Mariara, which last were from 132° to 135° 
Ft It has also been asserted that Humboldt saw living fishes 
Ge 
and not Chimborazo, that Humboldt made his observations. A 
Species called prefiadillas by the natives (Pimelodus eyclopum) 
S expelled from time to time from the crater, or clefts in the 
sides of it, in immense numbers; but he expressly states that 
the water expelled at the same time is not hot but cold and that 
the fishes are not so disfigured as to indicate that they had been 
= a high temperature.§ We have not been able to 
find authority for the statement with regard to the Geysers. '
