54 Reynolds and MoORBY, Equivalent of Heat 



g. Conclusions. 



We have, therefore, for the corrected value of the 



specific heat of water, expressed in mechanical units, 



measured at Manchester, 



7;6-94 ; 



at Greenwich, correcting for gravity, 



777-07 ; 



and in latitude 45^, at sea level, 



777-53 ; 



or, in metre-grammes, this last value becomes 



426-58, 

 as the equivalent of the mean value of the Centigrade 

 unit of heat. 



In absolute C.G.S. units this becomes 

 41,832,000 ergs.
