is an authority said so, not because a certain table or book 

 recommended it, but because our bodies are in part com- 

 posed of albuminoids, and we want the cows to give us in 

 milk what we need as food. I have put on this chart those 

 chemical compounds which are in the human body, of the 

 average weight of one hundred and forty-eight pounds.

Chemical Compounds in Human Body of One Hundred and Forty- 

 eight Potmds. 



The body needs these things to form the muscles and 

 nerves, blood and skin and other parts of the body. In per- 

 forming the functions of life some portion of those albumi- 

 noids are worn out from the blood and skin, the muscles and 

 nerves, and are carried off in the sewerage system from the 

 body. We must swallow something to replace what is worn 

 off, else we shall wear out; and I at least have no desire 

 to do that for forty years if I can help it. Therefore I 

 want to get from the cow a part of her albuminoids. 



Then in my body and in your body are fats, — fats for 

 heat and fats for lubrication. In feeding cows we find that 

 albuminoids are somehow in some measure transferred into 

 fats. Now, if you can give a boy food rich in all)uminoid8, 

 you give the boy what is called ell)ow grease to enlarge the 

 efficiency of his body. But if you feed a boy on pastry 

 and similar things you get something that is not elbow 

 grease. I do not know what you call it over here. On our 

 side we call it dyspepsia plus laziness. The same principle
