Cyanide of phenyl is obtained by the action of the phosphate on 

 cyanide of potassium. It is decomposed by boiling potash with 

 evolution of ammonia. 



Terchloride of phosphorus, when distilled with hydrate of phenyl, 

 seems to act at first similarly to the pentachloride, but the phosphite 

 of phenyl formed is decomposed by heat ; and among the products of 

 distillation is found a body boiling at 80 Cent., and possessing all 

 the properties of benzin, i. e. hydruret of phenyl. 



The formation of the iodide of phenyl is necessarily attended with 

 some difficulty, owing to the circumstance of phosphorus not com- 

 bining with more than three equivalents of iodine. Its boiling- 

 point is 190 Cent. 



Mr. Scrugham has had reason to confirm the statements of Lau- 

 rent and Gerhardt respecting the benzoate of phenyl, and has pre- 

 pared that compound in considerable quantities by the action of 

 chloride of benzoyle on phenylate of potash. Chloride and phos- 

 phate of phenyl could not be made to react on benzoate of potash. 



Chloride of cuminyl reacts with violence on phenylate of potash, 

 with formation of cuminate of phenyl, a compound analogous to the 

 benzoate. 



Chloride of phenyl was heated with phenylate of sodium, with a 

 view to the formation of oxide of phenyl, and there is no doubt that 

 this compound was formed by the reaction, as the correlative pro- 

 duct, chloride of sodium, was detected. But a further account of 

 this and other reactions is deferred until the experimental investiga- 

 tion is more advanced. 



Specimens of most of the compounds mentioned were exhibited.
