come over at about 270° F. ; the temperature at which the last por- 

 tion comes over may amount to 280° F. ^ 



The preparation of this product is difficult on account of the 

 bumping of the liquid, which sometimes comes over. It must be 

 heated slowly, and the retort should be ten times larger than required 

 to contain the liquid. 



Sulphocyanuretof methyle, after it has been purified by digestion 

 over chloride of calcium and rectification, has the following proper- 

 ties : it is a colourless and very hrapid liquid ; it has an alliaceous 

 odoiir ; its vapour is unpleasant and it stupefies ; it boils steadily at 

 about 270" F. Its density is MIS at about 61° F. Water dissolves 

 a very small portion, but it nevertheless acquires its odour ; it com- 

 bines with alcohol and aether in all proportions. 



In diflFused light chlorine acts very slowly upon it, producing fine 

 crj-stals of chloride of cyanogen ; and at the same time there is 

 formed a large quantity of a heavy yellow oil, which solidifies when 

 in contact with ammonia. 



Potash scarcely acts upon it in the cold. A solution when heated 

 decomposes it, and there are formed ammonia and bisulphuret of 

 methyle ; the residue contains cyanuret of potassium and carbonate 

 of potash. 



Solution of ammonia alters it readily, giving rise to a brown sub- 

 stance analogous to ulmine, and a small quantity of a crystallized 

 white matter. Heated in an alcoholic solution, the sulphocyanuret 

 of methyle is decomposed ; there are produced bisulphuret of methyle 

 and sulphocyanuret of potassium, easily recognised by the persalts 

 of iron. Moderately concentrated nitric acid dissolves it when 

 heated, but it separates entirely on cooling.

The mean of two experiments gave 2-559 as the density of its 

 vapour ; whereas, supposing its molecule to yield four volumes of 

 vapour, calculation would give 2-537. — Ann. de Ch. et de Ph., No-

ON SULPHOCYANURET AND BISULPHURET OF ETHYLE. 

 BY M. AUGUSTS CAHOURS. 

 Sulphocyanuret of Ethyle.— 'Qy d^istiWing a mixture of sulphovinate 

 of lime and persulphuret of potassium, both solutions being concen- 

 trated, a yellowish liquid is obtained, which after washing with water, 

 digesting on chloride of calcium, and cautious rectification, becomes 

 a colourless and very limpid liquid, the odour of which resembles 

 that of sulphocyanuretof methyle. Its density is 1020 at about 

 61° F. It is insoluble in water, but alcohol and aether dissolve it in
