Temperature of calorimeter . . . . . . . 64*05 F. 
„ water.70 - 0 ,, 
After 1 minute, temperature.69’82 „ 
„ 2 „ „ .69-8 „ 
Hence loss of heat 0 o- 18 F. in one minute. 
From the above and similar experiments the following table of loss of heat (the 
difference of temperature between water and original state of calorimeter being taken 
as argument) was arranged. 
For 30,000 grs. water <
