I ilbH— 0*00097 grain 
in air (<=15*0, 6=

Log AH= 1*325642, therefore ?;H = 330*717> ^^I = 330*856. Hence z;H=0*139. 
The true weight of I is greater than its apparent weight when compared with H, 
by 0*00017 grain, the weight of air displaced by a mass of platinum the volume of 
which at 0° is equal to the volume of 0*139 gr. of water of maximum density. Hence 
I=A+B4-r-)-A+Z— 0*00080 grain.
