The Acetyl Compound, C s rT ]2 N(CH 3 \\üO). This was prepared 

 in the usual way, by dissolving the base in anhydrous ether and 

 adding acetyl chloride toit. The hydrochloride of the acetyl com- 

 pound thus precipitated was purified by repeated recrystallization from 

 the mixture of alcohol and ether. It crystallizes in fine needles, in 

 appearance very much like the hydrochloride of the base. It is very 

 deliquescent. The free acetyl compound separates oui as an oil, on 

 adding caustic potash to its hydrochloride. The salt, dried over 

 calcium chloride, was anal ysed. 



0.2649 gram the hydrochloride of the acetyl compound gave 

 0.1906 gram AgCl.

 again extracted with ether. After repeating the same process of 

 washing several times, the oil, dried over calcium chloride, was once 

 distilled, h is a pale yellow oil, having the characteristic odour of 

 nitrosamine. It gives the well-known Liebermann's nitroso-reac- 

 tion : consequently the base itself is a secondary amine. 



The si »lui ion left after separating the nitroso-compound, was 

 treated with caustic potash, by which a small quantity of an oil was
