series, but containing sulphur in the place of some of the carbon. 

 A subsequent examination* of the reaction has shown that chlo- 

 ride of ethyle is formed at the same time, along with the zinc- salt 

 of a new acid. The reaction may be thus expressed : — 



(C 12 H 6 ) [S 2 O 4 ] CI + Zn C 4 H 5 = ZnO C 12 II 5 S 2 3 + C 4 H 5 CI.

sulphon-benzyle. of zinc. ethyle. 



Benzyle-sulphurous acid, the product of this reaction, stands 

 to sulphurous acid in the same relation as bcnzylc-sulphuric 

 acid to sulphuric acid; it is sulphurous acid (S 2 2 )0 2 in which 

 an atom of oxygen is replaced by bcnzylc. It crystallizes in 

 large prisms, often an inch long, and mostly occurring in stellate 

 groups. 



The author describes several of the salts of the new acid, and 

 also a series of experiments made with the view of finding a more 

 productive method of its preparation. 



Wurtz has continucdf his researches on the oxyethylenic bases 

 formed by the action of oxide of ethylene on ammonia. The 

 product of this action, when treated by hydrochloric acid, 

 consists mainly of the hydrochlorates of trioxethylenamine, 

 (€ 2 H 4 0) 3 NH 3 , and dioxethylenamine, (G 2 II 4 G) 2 NII 3 . The 

 former is insoluble ; and from the alcoholic mother-liquor, the 

 platinum-salt of the second, C 4 H n N9 2 , HClPtCl 2 , is precipi- 

 tated on the addition of bichloride of platinum. On the addi- 

 tion of ether to the mother-liquor, the platinum-salt of a third 

 base, monoxethylenaminc, is precipitated. It has the formula 

 (C 2 H 4 0) HC1, PtCl 2 , and crystallizes in golden-yellow nacreous 

 laminae. 



The hydrochlorates of monoxethylenaminc and of dioxethylen- 

 amine arc formed by the action of ammonia on hydrochloric 

 glycol when these substances, enclosed in strong vessels, are 

 heated in the water bath.

The base trioxethylenamine may be isolated and obtained as a 

 thick syrup by the action of oxide of silver on its hydrochlorate.
