Furfurtoluidine nitrate. — This was prepared in a manner similar to 

 the hydrochlorate, substituting the equivalent proportion of toluidine ni- 

 trate : 14 parts toluidine nitrate and 9 parts toluidine were dissolved in 

 100 parts hot alcohol, and 8 parts furfurol in an equal quantity (100 

 parts) of spirit added ; after standing some time the nitrate crystallized out 

 in deep purple needles. "When purified and analyzed it gave the following 

 numbers : —

 Furfurtoluidine. — The salts of furfurtoluidine, when treated with am- 

 monia solution, were decomposed in a manner similar to that already de- 

 scribed under the head furfur aniline, but not quite so readily. The crude 

 free furfurtoluidine, when digested with ether, dissolved, and on filtering the 

 solution, distilling off the ether, and drying the residue in a vacuum over 

 sulphuric acid, the base was obtained as a brown amorphous mass, which 

 is brittle and easily reduced to powder. It is not as fusible as furfuraniline, 

 and is far less readily decomposed. A carbon and hydrogen determination 

 of the freshly prepared base, purified by ether and dried in vacuo, gave the 

 following results :— -
