The values of T at integral values of the temperature over our 

 range were read off from the smooth curves. We give the values at 

 15°, 20°, and 25° C.

From this table we obtain the following results : — 

 Specific heat of water at 25° in terms of its 

 specific heat at 15°, deduced from columns 4 



and 6 = 0*99734 



Ditto from columns 4 and 5 = 0;°' 22 



Ditto from columns 5 and 6 = 0'^T46 



Mean
