88 On the Power of Fluids to conduct Heat. 
-N.B. This descent of half a degree was 
graudal, but did not commence till long after the 
beginning of the experiment.—After this the 
piece of ice was inclined to one side, by which 
nearly one half of it was immersed in the cooling 
liquid, and theinclosed bulb of the thermometer 
was now not more than an inch from the cold 
mixture. »

The ice now weighed 123 ounces: the rest 
had been liquified by the operation of the saline 
liquor. 
This experiment, I think, decidedly proves 
that ice is a worse conductor of heat than 
water :—Indeed this is not wonderful ; for it is 
said, that ice at a low temperature becomes an 
electric. 
It is certainly a remarkable circumstance, 
but not at all inconsistent with the known laws 
of heat, that in a mixture of hot and cold
