On Sugar as a Food. 



[Dec. 14, 



(If ounces) at 3.50 P.M. the food partaken of, in all other respects, 

 being on each day exactly the same. 



Table showing total Gain in an eight-hour Day's Muscular Work 

 produced by taking 250 grams (8| ounces) of Sugar in addition 

 to an Ordinary Diet. 



It will be here noticed that the gain in work during the nine hours 

 by taking sugar was in the case of the left finger 22'032 per cent., 

 and the right finger 35*858 per cent. And that fatigue was retarded 

 in the one case 12 seconds and in the other 180 seconds. 



Thus it is seen that when 250 grams (8f ounces) of sugar is taken 

 along with ordinary diet, it not only prolongs the time during which 

 work can be done, but also increases the total amount of work per- 

 formed in eight hours. It is further seen that the sugar taken at 

 3.50 P.M. had the effect of increasing the work done at 5.30 and 

 5.40 P.M., and that, instead of there being the usual diurnal fall in the 

 amount of work done in the afternoon, there was actually an increase 

 in the total amount of work accomplished.
