In these analyses, as in the former, the phosphate of 

 lime was also exposed to a red heat, and consequently was 

 reduced to a greater degree of dryness than that in which 

 it existed in tlie tooth. 



In all of them the carbonate of lime was dried in a heat 

 of 21 2^*, (above which it would have been liable \o decom- 

 position), and the gelatine of the tliree last in the same 

 temperature.
