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



muscles with a sufficiency of working material, and the advantage, 

 consequently, is most markedly seen in the total amount of work per- 

 formed. 



Having found that sugar when taken by itself is undoubtedly a 

 muscular food, it was next necessary to ascertain its value when it is 

 taken along with and in addition to an ordinary diet. 



First, in order to see the effects of sugar added to a frugal meal, 

 200 grams (7 ounces) of sugar were taken at 9 A.M., after a breakfast, 

 at 8 A.M., of a cup of coffee, with milk, and two rusks. 



Table showing Gain in Muscular Work obtained by adding 200 grams 

 (7 ounces) of Sugar to a Frugal Breakfast. 



Here it is seen that 200 grams (7 ounces) of sugar increased the 

 amount of work performed, both by the left and right hand. The 

 increase in the quantity of work done being most marked in the case 

 of the right finger, for it was 39'06 per cent., whereas the left was 

 only 6'16 per cent. It is farther seen that, although the taking of 

 the sugar caused an immediate increase in the work done, the in- 

 crease was far more marked two and a half hours later; that is to 

 say, when its assimilation had taken place. 



Having thus ascertained that sugar increases the power of doing 

 muscular work when added to a small meal, 1 will now give an 

 example of what it does when added to a full one ; that is to say, a 

 luncheon consisting of beefsteak with vegetables, an omelet, and
