added. then tlie liquid reiidered alkaline and heated for a short 

 time to the boil. The substance left undissolved bas been filtered 

 off, washed well witb water and crystallised several times f'rom 

 glacial acetie acid. Obtained yellow needles melting at 279 — 280°, 

 which dissolve with difficulty in alcohol, ether, aeeton, benzène 

 and Chloroform. The alcoholic solution yields with an ammoniacal 

 solution of silver nitrate a red precipitate.

The alkaline filtrate from the above yielded. on being neutra- 

 lised, a white precipitate. which was dissolved in a concentrated so- 

 lution of sodium hydrate and the solution kept boiling for several 

 hours in order to split off the acetyl group. The alkaline solution 

 was then diluted with water and the free amino Compound preci- 

 pitated by adding hydrochloric acid. After washing it thoroughly 

 with water it bas been crystallised several times from alcohol. 

 It represents orange needles, soluble with difficulty in alcohol, ben- 

 zène, Chloroform, easier soluble in ether and aeeton. The solution 

 in conc. hydrochloric acid yields with ether a red coloration. Cau- 

 stic, diluted alkalis take it up readily , whereas concentrated 

 yield a white body which is no doubt the corresponding sodium 

 Compound. M. p. 249 — 250".
