20 SCHMITZ, On a Method of Ice Calorimetry. 



As might be expected from what precedes, the result 

 given by the ice method is generally in excess of that 

 given by the method of mixtures. The exceptions are 

 copper, nickel, and cobalt. In the case of nickel the ice- 

 coated cylinder was too large for the drying apparatus, 

 and was dried by hand ; the result is no doubt slightly too 

 small on this account, probably by about one per cent. 



To sum up, it appears that, with suitable precautions, 

 results obtained by the present method will probably be 

 within two or three per cent, of the truth. When this 

 degree of accuracy will serve, the method may be recom- 

 mended as more expeditious and much less troublesome 

 than the method of mixtures.
