The corresponding products of vegetables are, 1st, gluten, 

 and 2d, its peculiar principle, detected by Liebig, called veg- 

 etable fibrine ; 3d, vegetable albumen ; 4th, legumine, or 

 vegetable caseine. The two last are identical in composition 

 and properties, with the albumen and caseine of animals. 

 Indeed, it has been suggested, that animals never create 

 either of the above, but draw them ready formed from 

 plants. The composition of the vegetable principles author- 

 izes such a conclusion. By the analyses of Drs. Scherer 

 and Jones, in the laboratory of Liebig, these are constituted 

 as follows : 



Gluten. Vegt. fibrine. Albumen, Caseine.

Caseine contains no phosphorus, but both animal and veg- 

 etable principles, comprised under the above names, are 

 always combined with alkalies, lime, magnesia, iron, sulphur, 

 and phosphoric acid. The above are the organized principles 

 of living bodies, and are distinguished from all others by 

 their nitrogen. Substances not containing this element are 

 said to be organic, but not organized.
