Srom Water and other Liquids, Sc. 555 - 
water of the observed temperature. This me- 
thod may also be used for other liquids. {[t 
may be proper to observe the various thermo- 
meters used in these experiments were duly ad. 
justed to a good standard one. 
After repeated experiments by all these me- 
thods, and a careful comparison of the results, 
I was enabled to digest the following table of 
the force of steam from water in all the temper- 
atures from 32° to 212°, 
Two important enquiries still remained: the 
first, to determine the force of steam from water 
above 212° and below 32°; the second, to deter- 
mine the comparative forces of vapour from 
other liquids, These enquiries seemed indepen- 
dent of each other; notwithstanding which I 
found them in reality connected. 
Upon examination of the numbers in the table 
within the limits just mentioned, there appears 
something like a geometrical progression in the 
forces of vapour; the ratio however, instead of 
being constant, is a gradually diminishing one: 
thus, the force at 32°= —,200 inch.
