CHAPTER III. 





ALIMENTATION AND THE EXPENDITURE. 



98. Alimentary Rations. The name of alimentary ration is 

 given to a determined weight of aliments. This ration can be 

 pure or mixed according to whether it comprises one or several 

 kinds of aliments. Its calorific power results from its immediate 

 composition ( 95) : thus a ration of a 100 grammes of bread and 

 a 100 grammes of dried beans gives : 



(Carbo-hydrates ... 107-26 grms., or 439-77 Cal. (== 107-26x4-10) 

 JFats 1-60 grms. or 14-56 Cal. (= 1-60x9-10) 



IProteids 28-23grms. or 115-75 Cal. (= 28-23x4-10) 



Calorific power of the ration 570-08 Calories 



To facilitate the calculation of the energetic values of different 

 rations, veritable encyclopedias have been published giving the 

 immediate compositions of aliments. The following tables are 

 drawn from the work of Balland f 1 ) ; they especially concern 

 French alimentation, as those of Kcenig ( 2 ) concern German 



products, 

 practical. 



It is superfluous to say that these tables are extremely
