fathoms, that was the temperature of the -whole 

 mass of water heneath, down to the greatest deptli 

 explored." The temperature at 100 fathoms varies 

 very little from 13° C. (55o° Fahrenheit), and the 

 Mediterranean attains in many places a depth of up- 

 Avards of 1,500 fathoms, so that here we have the 

 strange phenomenon of an underlying mass of water, 

 1,400 fathoms deep, of a uniform moderate tempeni- 

 ture ; a state of things singularly diiferent from that 

 which obtains at like depths in the Atlantic. Er. 

 Car2:)enter's ingenious speculations as to the cause 

 of this difference will he considered later.
