We can also show how chondriu may be supposed to be 

 formed from protein by the addition of oxygen and hydrogen :

We may, in a similar manner, conceive that glutin, urea, 

 and lactic acid are formed from protein by the absorption of 

 oxygen, and the liberation of carbonic acid ; for

If we conceive that the blood-corpuscles are formed of globulin 

 (a protein-compound), haematin, and margarin, they may, by 

 the al)sorption of oxygen and the development of carbonic acid, 

 be decomposed into many other substances, as, for instance, 

 into protein, cholesterin, margaric acid, urea, uric acid, and 

 lactic acid; for,

Many similar illustrations of possible metamorphic actions 

 might be adduced; but, as they do not contribute to the ad- 

 vancement of chemical science, we shall omit to notice them.
