Lassaigne analyzed the callus of a broken bone with the dif- 

 ferent sound parts of the bone in its neighbourhood, and obtained 

 the following results :

According to Berzelius's analysis, the proportion of carbonate of 

 lime is much greater in the human bone than in that of the ox. But 

 the analysis of Fourcroy and Vauquelin gives a different result. 

 The following table by Fernandez de Barros shows the relative 

 quantities of phosphate and carbonate of lime found in the ashes 

 of the bones of various animals :* 



Phosphate of lime. Carbonate of lime. 



Lion, 95' . 2-5

Berzelius analyzed the ashes of human bones, (we do not know 

 of what age,) and found them composed of,
