economy, but must be taken into the system already 

 formed. 



252. Casein is an essential ingredient in milk and in 

 cheese, whence its name (caseus, Latin, cheese.) 



253. Albumen is nearly identical in composition with 

 the white of an egg (of which albumen is the Latin name) 

 and is found in many parts of the human body and the 

 bodies of other animals. It is always found dissolved in 

 the sap and juices of living plants. 



254. &quot;Wheat contains from 8 to 35 per cent, of Gluten, 

 Indian corn 12, beans 10, rye 9 to 13, barley 3 to 6, oats 

 2 to 5, potatoes 3 to 4, and a little is found in beets, 

 turnips and cabbages. 



255. The fact that wheat varies so much in the gluten 

 it contains is one very instructive to the farmer. When 

 fed with the very richest manures, especially those con 

 taining animal substances, wheat not only yields more 

 abundantly, but the grain is richer in this most nourish 

 ing element. For Animal Fibrine is the essential portion 

 of the fibrous part or muscle of the flesh of animals. 



356. The elements of every thing in the body of a man 

 or any other animal must have come into the system in 

 the water or air, or in the vegetable and animal food 

 which he has consumed. To exist in the body of an 

 animal, they must have been found in the vegetables on 

 which it has been nourished, and, before that, in the soil 

 out of which the vegetables grew, or in the atmosphere 

 by which all have been surrounded. 



257. What it is which gives color to the leaves of Plants. 

 The green color is owing to a substance called Chlorophyl, 

 (leaf-green.) This is found in the leaves and in the bark 

 of the newly formed twigs of nearly all flowering plants. 

 It is composed of a white, wax-like substance, and a
