in tlie inii|>rrature of the water; the fifth column, under the heading Aj0, the 

 difference pnxlinvd in the temperature of the glass; the sixth column gives the 

 \\virlil of the water in the calorimeter, to which is added the approximate water 

 equivalent of the calorimeter (137 gr.) ; the seventh column gives the mean specific 

 heat of glass for the temperature interval indicated, taking the specific heat of water 

 as unity in all cases. 



TABLE VI. 



Since the changes of water temperature took place at different points of the 

 temperature range, they require to be multiplied by the values of the specific heat 

 of water at the various points. These values were obtained from the preliminary 

 rough curve of the values of J, the values used being set out in Table VII. This 



TABLE VII. 



table gives the values for the mean specific heats in 15 calories, corrected for the 

 ti-niperature of the water, and also reduced to exact temperature figures, from which 

 .-tr- 1 calculated the mean values of the specific heat from to 0. In the table S IS ' 

 indicates the mean value of S between 16 C. and the temperature in the second 

 column, whilst So* indicates the mean value from to 0. The mean of the first four
