CHAPTER XVIII. 



DIETARY IN DETAIL. 



As far as our digestive organs at their present stage of evolution 

 are concerned, it has been ascertained with sufficient accuracy for all 

 intents and purposes, what character and quantity of food is required 

 for men in the temperate zone. We have prison diets, soldiers' diets, 

 sailors' diets, etc., now arranged on a scientific basis in place of the

Yeo's table for the adult is: 



Albuminous foods 100 grammes. 



Fats 90 grammes. 



Starch 300 grammes. 



Salts 30 grammes. 



Water 2,800 grammes.

Carbohydrates 392.3 grammes 



Fats 88.4 grammes.

 grammes. 



Dr. Chaumont's table for an adult of 150 pounds weight and doing

Albuminoids 4.50 ounces. 



Fats 3.75 ounces. 



Carbohydrates 18.00 ounces. 



Salts 1.12 ounces. 



The British soldier's ration is: 



Albuminoids 3.86 ounces. 



Fats 1.30 ounces 



Carbohydrates 17.43 ounces. 



Salts 81 ounce. 



This ration is deficient in fats, and the high mortality of British 

 soldiers in garrison may be attributed in part to this error. A con-
