CHEMICAL TOXICOLOGY 301 



method of identification may be based on — (a) its separation 

 by distillation from alkaline solution; (6) its conversion 

 into the dibenzoyl compound (by means of alkali and 

 benzoyl chloride). The dibenzoyl compound when pure 

 melts at 130° C. Its detection would thus probably form 

 a valuable guide as to the nature of these poisonings.
