SCIENTIP^IC RECORD FOR 1885. 



Etherpal salts of many of these bodies were also prepared and studied. 



By lieatiug hydioxylaaiiue aud hydrochloric acid with benzoyltrime- 

 thyleiie, in a sealed tube, a complicated reaction sets in, yielding a deep- 

 blue solution with an intense brick-red fluorescence. This solution 

 proved to contain two distinct bases; that soluble in ether was found 

 to have the constitution 0300.^8^202. It is easily soluble in acetone, ani- 

 line, and nitrobenzene, more sparingly in alcohol, ether, aud in benzene. 

 If the brownish-red alcoholic solution be treated with zinc dust and 

 ammonia, it i.s reduced and becomes colorless; on agitating with air it 

 is reoxidized. The salts of this base are easily obtained, and form deep- 

 blue solutions with a most magnificent brick red fluorescence. The hy-
