Residuaty carbonaceous mass. — It was not incinerated with 

 platinum, but in oxygen gas ; hence there was a loss. I have 

 already remarked that the proteine substances of vegetables 

 and animals alone appear to be meroxidic bodies ; all others 

 appear to be of a teleoxidic nature. The white of hen's eggs, 

 however, forms a remarkable exception to all the other pro- 

 teine substances which have been examined, in consequence 

 of the very small quantity of anoxidic substance which it 

 contains. The amount of ash is very small. In both experi- 

 ments the charred mass contained silica in the form of sand, 

 which, however, was deducted from the ash. The following 

 was the composition of the two ashes : —

These results differ very considerably; the cause must be 

 determined by future experiments. 



On arranging the constituents in the form of salts, we find 

 in the first experiment i-phosphoric acid and some very basic 

 silicates ; in the second only i-phosphoric acid and less basic 

 silicates.
