fied carbon dioxide, showed microscopic needles and leaf crystals 

 which rapidly llquefied. The oily liquid yielded a green Solution 

 with strong hydrochloric acid. This Solution was evaporated over 

 a water bath. Portions of the syrupy fluid remaining just before 

 dryness were placed on a slide with a platinum loop and allowed to 

 cool. There formed microscopic crystals of brown leaves and balls. 



A control was run by boiling chloral hydrate and extracting with 

 ether. The ether Solution was evaporated over an incandescent 

 lamp, when typical chloral hydrate leaves and clumps crystal- 

 lized out. 



The nature of the various products has not been determined, 

 They are now under investigation.
