support this view. Thus many races (Tyrolese, Africans, 

 Japanese, Chinese, etc.) consume a far higher proportion of carbo- 

 hydrates than of proteids. The Finns, for example, hardly 

 consume 40 grammes of albumens per diem.f 1 ) 



The foregoing inquiries have established two important facts : 



(1) The gross dynamic expenditure in the case of heavy work 

 can reach 80 Calories per kilogramme per diem, i.e., 3-33 Calories 

 per kg. per hour. Under normal condtiions it appears that this 

 expenditure cannot be exceeded for several days continuously. 



This gives for an adult weighing 65 kg. a total calorific equi- 

 valent of 80 X 65 = 5,200 Calories in 24 hours. 



The static expenditure in the same period was found to be 

 1-5 x 24 X 65 = 2,320 Calories. 



Hence the greatest daily total of work is equivalent to -25 

 (5,200 -2,320) = 715 Calories = 300,000 kgm., approximately. 



(2) The normal diet is generally the most readily assimilated 

 and gives the best yield. It should not be altered, but attention 

 should be directed to improving its quality and assuring that it 

 is adequate in quantity and proportions. ( 2 j

These quantities are undoubtedly too low since octroi posts 

 do not exist at several towns. 



The following table giving the consumption per head of rlco- 

 holic beverages has been compiled . from the statistics of the 

 Ministry of Finance, based on the customs house records :

( 2 ) The traditional ideas in regard to the selection of food stuffs are not to 

 be considered as condemned by the results of scientific research. The latter 

 draws attention to the " psychic influences " which stimulate the digestive 

 secretions (Pawloff).
