Hydruchlorate. — The hydrochlorate of benzoline is a sparingly-soluble salt even in 

 boiling water. It crystallizes from a hot solution in small but exceedingly brilliant 

 colourless needles, which effloresce in the dry vacuum. It has, in common with 

 the other salts, an intensely bitter taste. The salt, deprived of its water of crystal- 

 lization, gave the following analytical results : —

The crystallized salt was found to lose by efflorescence 2*4 per cent, of water, 

 corresponding very nearly to one equivalent. 



The hydrochlorate of benzoline forms with bichloride of platinum an insoluble 

 double salt of a pale yellow colour, not further examined. 



Nitrdie.—ThQ nitrate is even less soluble than the preceding salt ; the crystals are
