at different Degrees of Heat, 26^ 



Bladh, in the Memoirs of the Academy of Stockhohii for the 

 year 1776, vvhofe determinations, as far as they reached, agreed 

 very nearly with mine. The water I ufed was common water 

 well boiled and filtered. The experiments were for the moil 

 part three times repeated, and the difference in each trial 

 amounted to a very few grains. 



Hence we fee, that a cubic foot of water weighs 4^5,3 grains 

 more at 42° than at 62°, and confequently is equal to 1001,109 

 avoirdupois ounces, and in the temperature of 82^ it weighs lels 

 than at 62° by 788,5 grains, and therefore is equal to 998,198 

 ounces. At the boiHng point it wants 16589 grains, or 37,915 

 ounces of the weight it poffefles at 62°, and confequently 

 weighs but 962,085 ounces, &c^
