274 DIETETICAL PROPERTIES. 



But there is still another effect of coffee that of 

 checking the too rapid consumption of nitrogeneous 

 matter in the system which, while not nutritious 

 in itself, yet possesses an indirect nutritive value; this 

 result, added to its stimulating character, have made 

 it the chosen beverage for breakfast, and therefore

 given it as an experiment, and then some ground coffee
