burnt in an atmosphere of oxygen, would allow of the volatili- 

 zation of a considerable portion of the alkaline phosphates. 

 The separation of the white from the yolk can be easily 

 effected, by well boiling the eggs in water until they become 

 hard. 



The relative proportion of the white and yolk was not ex- 

 actly the same in all the eggs. The following results were 

 obtained in regard to this point : — 



Four eggs yielded 

 Sixteen eggs yielded .

In both analyses a little more carbonic acid was found than 

 could be combined with the alkali. This is remarkable; 

 because in the aqueous extracts of the carbonized mass of 

 other organic substances, considerably less carbonic acid was 

 frequently found than was requisite for the saturation of the 

 alkali, a considerable portion of the carbonic acid being fre- 

 quently reduced to carbonic oxide by the carbon. 



Muriatic extract. — As in the first experiment, the presence 

 of the alkalies was overlooked ; the result of the second only 

 is given : —
