Complete Formula for Calculating the Specific Seat. 



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 — Y X '000063 

 is sufficient. 



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



g _ 1-000589|>, —Y x 0-000636] [536-5 + 07(1 00 - *,°) ] 



the several weights observed baiug supposed reduced to vacuo as 

 usual, otherwise the letters being as before.
