all proportions. It acts similarly to sulphoc3'anuret of methyle upon 

 jeagents. 



Chlorine and bromine act energetically on the sulphur compounds 

 of methyle and of ethyle. With bromine perfectly well-crystallized 

 combinations are obtained. 



By analysis this substance appears to be composed of — 



C'^ 4500, or in 100 parts 41-38 



H'o .... 62-5 5-74 



N"- 177-0 16-09 



S« 400-0 .... 36-79

By experiment the density of the vapour of this substance was 

 found to be 3-018, while calculation would lead to 3-032, supposing 

 the molecule represented four volumes of vapour. 



Bisulphuret and Tersulphuret of Ethyle. — The former was obtained 

 in considerable quantity by distilling a mixture of sulphovinate of 

 lime and persulphuret of potassium ; but towards the end of the 

 rectification of the rough product there came over a 3'ellowish and 

 slightly volatile liquid, which gave by analysis results which tended 

 to show that it was to be considered as a tersulphuret of ethyle. 



M. Cahours analysed the bisulphuret of ethyle, and his results 

 agreed precisely with those previously obtained by M. P. Morin, 

 C* H'° S*. The density of its vapour was found by experiment to 

 be 4-270, and by calculation 4-2-40, on the supposition that the mo- 

 lecule of this compound furnishes two volumes of vapour. 



Chlorine vividly acts ujion the two compounds above described ; 

 moderately concentrated nitric acid does the same, a portion of the 

 sulphur being converted into sulphuric acid : there is also produced 

 an acid susceptible of forming soluble and crystallizable salts with 

 potash, barytes, and oxide of lead. — Ann. de Ch. et de Phys., No-

ANALYSIS OF THE WHITE DIOPSIDE. 



M. Hermann found this substance from Achmatowsk to consist of — 



Silica 53-97 



Lime 25-60 



Magnesia 17-86 



Protoxide of iron 2-00 



Protoxide of manganese . . 0-57 



100-00 

 This analysis corresponds to the formula Si* M-* O'' : [Si* (Ca^ 

 Mg") O"]. — Journ. de Pharm. et de Ch., Novembre 1846.
