Salicine, C 1S H 18 O V Salicine on electrolysis yielded 

 salicylic aldehyde and salicylic acid (Tichanowitsch 1 ). 



9. Electrolysis of Blood. 



The defibrinated blood of a dog was submitted to 

 electrolysis by Becquerel. He made use of platinum 

 electrodes and a current furnished by a battery of 

 three Daniel cells. At the negative pole he observed 

 the following phenomena: 



The blood became brown and alkaline, and con- 

 tained neither white nor red corpuscles; it possessed 

 the property of gradually dissolving blood-corpuscles 

 and had the odor of putrid meat. 



At the positive pole undecomposed and partially 

 decomposed blood-corpuscles were present in large 

 quantities. The fluid gave a precipitate of albumen 

 with nitric acid, mercuric chloride, and lead acetate. 



10. Electrolysis of Albumen. 



When an albumen solution was electrolyzed by 

 Dumas and Prevost, under conditions similar to those 

 used by Becquerel for blood, the alkali metal went to 

 the negative pole, hydrogen was evolved, and acetic 

 and phosphoric acids appeared at the positive pole. 

 The result of this is that the albumen is coagulated
