in the Production of Muscular Work.

bread, along with a quarter bottle of red Italian table wine, and after 

 it a small cup of black coffee. 



In this case 250 grams (8J ounces) of sugar were taken along with 

 the meal at 12.30. 



Table showing Gain in Muscular Work caused by the addition of 

 250 grams of Sugar to a Full Meal. 



In this table it is seen that when 250 grams (8J ounces) of sugar 

 are added to a full meal the power of doing muscular work is in- 

 creased. 



In this instance it was the left hand that showed the greatest in- 

 crease in working power, for it gave on the sugar day 16'599 per 

 cent., while the right only yielded 8'433 per cent, more work. As 

 usual, on both of the above days exactly the same quantities of food 

 were taken, so that the only difference in them was the taking of 

 250 grams of sugar on the one and not on the other day. From this 

 one is forced to conclude that sugar when added even to a copious 

 meal has a most important power in increasing the human capabilities 

 of doing muscular work. 



I now give the result of the amount of work done on 250 grams cf 

 sugar in two periods of eight hours each, where in one case the sugar 

 was taken in divided portions at three different times 100 grams 

 (3ijr ounces) at 8 A.M., and 100 grams again at 12 A.M., and 50 grams
