630 Mr. nair.ne's Account of 
the next day; it was then. put again into the receiver, 
and the degree of exhauftion, according to the barometer- 
gage, was 300, and according to the pear-gage 3500. 
Being now perfectly fatisfied that the variation in the 
teftimony of the pear and barometer-gages was occa- 
iioned by the moifture contained in the fubftances I had 
put into the receiver afluming the form of vapour; I 
determined next to try what would be the effedt of the 
vapour which might arife from fmall quantities of dif- 
ferent fluids, and from fome other fubftances containing 
moifture of various kinds. 
Subfiances put into the receiver.
