-EXPERIMENT LXI. 
Frefh aether being put into the phial to what was re- 
maining, the thermometer rofe to 30° above o : the pump 
was then worked again conftantly for half an hour; yet 
by the barometer-gage the degree of exliauftion was 
now not more than 1 6, and the degree of cold produced 
did not exceed the nth degree below o, as appeared by 
the quickfilver in the thermometer. The air being let 
into the receiver, the remaining aether was examined, 
and there were found feveral pieces of ice at the bottom 
of the phial, fome of them as big as large peas, which, 
when the aether became nearly of the heat of 32 0 or 
freezing point of water, were intirely diffolved. 
The air-pump with which thefe experiments were 
•made exhaufted above 400 times before the aether was 
jmt under the receiver.
