OBSERVATIONS FOR FINDING THE DENSITY OF T. 
813 
cess was followed as in finding the density of V. The thermometers H, P were 
suspended in the water with their bulbs in a horizontal plane through the middle 
of T. t denotes the temperature of the air in centesimal degrees ; h the height of 
the mercury in the barometer in millimetres, reduced to 0° C.; 100 parts =0'220 
grain.
