EXPERIMENT STATION RECORD. 



to rabbits and heus. The author studied the effect of xylose in this 

 comiectiDii, using rabbits. The subjects were rendered glycogen -free 

 by strychnine, given a narcotic to keep them quiet, and killed 11 or 12 

 hours after feeding the xylose. Doses of 3.75, 8, and 10 gni. of xylose 

 were given. No glycogen formation was observed in these experiments, 

 and the author believes that they show that xylose is not capable of form- 

 ing in the body glycogen or other substance giving tlie reactions of gly- 

 cogen. He believes further that xylose does not indirectly promote the 

 formation of glycogen, as by a conserving action on other substances 

 (albumen) known to produce glycogen directly.

 8 {1894), No. 19, pi 274). — An experiment indicated that feeding cows exclusively on
