ating dish. The diluted blood subjected to spectroscopic examination 

 showed the two dark absorption bands, which were not changed on warm- 

 ing the blood with ammonium sulfide. Ferrous sulfate did not cause the 

 blood to darken, as is the case with normal blood. Two cubic centimeters 

 of the "carbon monoxide" blood from the guinea pig was mixed with an 

 equal quantity of water and three drops of a one-third saturated solution 

 of copper sulfate gave a brick-red precipitate, while normal blood gives 

 a greenish-brown precipitate. 



A canary bird lived less than fifteen seconds in gas from the kelp 

 bulb. Removal of the feathers from the breast showed that the skin was

 subjected to spectroscopic examination and compared with blood from a 

 similar chick killed by decapitation, showed results analogous to those pre-
