Benzol and styrolene passed together through a red hot tube gave 
anthracene in large quantity, together with naphtalin and a hydrocarbon 
resembling phenyl. The anthracene results from the direct action of the 
styrolene upon benzol according to the equation 
C,2H,[C,H,(H.)]4+0,.H,(H,)=C,.H,|C, 2H,(C,H,)]+2H,.- 
Berthelot thinks that in this case the naphtalin results from the action 
anthracene is found in large quantity.

calling it amyl-hydroxalate of ethyl and regarding it as oxalate of a 
in which one atom of oxygen is replaced by one of amyl and oné 
hydrogen. This body may be compared with lactate of ethyl from which 
it may be theoretically derived by replacing an atom of methyl by ™ 
atom of amyl.
