Dr. V. Harley. Sugar as a Food [Dec. 14, 



in the production of muscular work. During a twenty-four hours' 

 fast on one day water alone was drunk, on another day 500 grams of 

 sugar was taken in an equal quantity of water. 



Table showing the Increase in the Muscular Power of 30 Voluntary 

 Contractions produced by 500 grams (17-J ounces) of Sugar. 200 

 grams (7 ounces) being taken at 8.30 ; 100 (3J ounces) at 11 A.M., at 

 2 P.M., and 5 P.M. 



The above table shows that sugar when taken alone increases the 

 amount of muscular work done, as shown by thirty voluntary con- 

 tractions. The left middle finger accomplished, during five periods, 

 21*459 kilos, of work, as against 17*079 kilos, on the fasting day, show- 

 ing an increase in the muscle-working power, on sugar, of 25*646 per 

 cent. The right hand, during the four periods when sugar was taken, 

 performed 15*316 kilos, of work, as against 11*544 kilos, while fasting, 

 thus showing the still higher gain in muscular power, on sugar, of 

 32*675 per cent. 



The effect of sugar in retarding the approach of fatigue was next 

 estimated.
