EXPERIMENT I, 
At half paft one o’clock, when the thermometer 
pointed to - 22 0 , the fnOw contiguous to the ball was 
blown upon for two minutes by a pair of hand-bellows, 
held with the pipe nearly horizontal, and half a foot 
above the furface of the fnow. The bellows had been 
lying out on the fnow to cool from the time we firft came 
over; and, in order to promote their cooling, they were 
now and then wrought in the open air. Gare was alfo 
taken to Hand to leeward of the thermometer, and to ex- 
tend the bellows as far as poflible from the body in the 
time of blowing. W e were furprifed to find, however, 
notwithftanding all our precautions, that the thermome- 
ter at the end of the experiment had got up no lefs than 
I 0 °, for k now Panted only to - 1 2 0 . In this experi- 
ment the nolle of the bellows was held about fix inches 
from the thermometer, but the blaft, though moderate, 
frequently drifted away the fnow from the ball.
