1. On a new class of Sulphur compounds—Vow Oxrre.z has suc- 
ceeded in shewing that sulphur, like selenium, tellurium, lead, tin and 
many other elements, is capable of forming a true organic base with 
ethyl, and doubtless, therefore, with other organic radicals. The iodid of 
the new radical is easily formed by the direct combination of sulphid of 
ethyl with iodid of ethyl, the reaction being expressed by the equation 
CO, Hit = (Capel. 
The ney iodid is a beautiful crystalline body which is easily soluble in 
water and alcohol and crystallizes from its solutions unchan itrate 
of silver precipitates iodine from an aqueous solution of iodid of triethyl- 
sulfyl as iodid of silver, while a nitrate of the new base remains in 
solution. Oxyd of silver and water digested with the iodid yield the 
ngaged in investigations which appear to show that nitric acid con- 
Verts triethyl-sulfyl into a new base which contains S, as a hexatomic 
mstead of a tetratomic element, the hydrated oxyd being probably 
@ rose color resembling that produced in chloroform by traces of iodine. 
Of course the precautions usual in testing for iron by sulpho-cyanid of 
Potassium must be taken in employing Natanson’s ss. By u 
of it, the author easily detected iron in a solution of chtorid of platinum, 
in which, on account of the yellow color, sulphocyanid of potassium as
