by that means rendered eafier to be cooled, was 
well known to the ancients. 
Ariftotle obferves. That water freezes the 
fooner for having been before heated; and, that 
this fad was even known to fome barbarous 
people upon the Euxine Sea, who made ufe of 
Ice as a kind of cement for their huts; and that the 
water frozen for this purpofe, was firft heated, in

alfo mentions it as a difcovery of Nero, to boil 
the water that was intended to be frozen', as that

that they reproved their fervants, if the water 
they provided for freezing was not previoufly 
heated.”
