Towards the end of the experiment the arsenic fowl appeared to 

 be suffering somewhat from the toxic action of the poison, consequently 

 the arsenic was discontinued after the 18th, but the fowl died on the 

 21st, and was immediately analyzed. 



In J5, no trace of a reduction could be obtained for glycogen and 

 only an unweighable trace for sugar. 



In this experiment, therefore, we find a decided loss in body weight 

 under the influence of the arsenic, a loss in the weight of the liver, a 

 slight diminution in the liver fat and neai'ly a complete disappear- 

 ance of both glycogen and sugar.
