in appreciable quantity by the digestion process. I ascertained 

 however that it is a soluble salt. 



Hyposulphite of Furf urine. — On addition of hyposul- 

 phite of soda to a solution of crystallized hydrochlorate of this 

 base, an oil separates, which passes, after some time, into co- 

 lourless needles. 



Hyposulphite of Aniline may be formed by adding the soda 

 salt to a strong solution of the neutral hydrochlorate of this vola- 

 tile base, when it is speedily deposited in pearly scales. I could 

 not obtain it pure, however, for it does not admit of re-crystal- 

 lization. When taken up in warm water, in which it is readily 

 soluble, the fluid becomes milky before the boiling point is 

 reached; at this period aniline may be perceived to escape 

 by its odour, and, immediately after, sulphurous acid is evolved 

 in large quantity, and the salt is quite decomposed, the base 

 not being a sufficiently powerful one to retain the hyposul- 

 phurous acid. 



The following is a tabular view of the salts whose analyses 

 are given in this paper : —
