On the Method of Condensation in Calorimetry. 371 



Complete Formula for Calculating the Specific Heat. 



Collecting the foregoing corrections we get a formula for use if 

 very considerable accuracy be desirable, but it is to be observed that 

 under any ordinary circumstances correction (1) on w 1 of —V X '000063 

 is sufficient. 



The complete formula for S, the specific heat, is — 



g _ l-000589[w,-VxO-000636][536-5 + 07(100-f a °)] 



the several weights observed being supposed reduced to vacuo as 

 usual, otherwise the letters being as before.
