Silver Lake, May 19, 1823. 

 , Dear Sir, — Shortly after my return home (April 12th), I had the 

 temperature of the water in this lake, and another which is about four 

 miles from it, ascertained. A bottle of water was sunk to the bottom 

 in this lake, 90 feet; in the other, 75 feet; and after lying twenty- 

 four hours, drawn up, and the water contained in it was found to be, 

 in both instances, 42° of Fahr. In midsummer, last year, I tried the 

 temperature of the water here in the manner mentioned above, and 

 found it, at an hundred feet deep, to be 46°. 



Very respectfully, 



R. H. ROSE. 



Prof. Frazer alluded to the experiments made in the Gulf 

 Stream by the late Lieut. George Bache, of the U. S. Coast 

 Survey. The temperature of the surface was 80° Fahr.; but 

 at the depth of 1500 fathoms it reached as low as 37°.
