less it be that it discolors them. Another part of the crystals, 
re having undergone a potash solution, gave a solid and very gluey 
deposit of a dirty yellow; the solution became yellowish; the 
sides of the vessel, in which the operation was performed, became 
very greasy, the deposits, as well as the potash — had a 
very strong and decided smell of cucumber. ~ 
- The red liquor, in the midst of which was the mass of eeheiiey 
slightly smoked in the open air, though its point of ebullition’ 
was pretty high; its density is greater than that of sulphuric 
acid, but apart floats even above the water, which betokens a 
complex liquid; it is insoluble in water and in ether, but rather 
soluble in alcohol ; however, the alcoholic solution having evap- 
orated, appears to leave the liquor untouched ; water brings about 
a powdery deposit of a currant red. 
~ This lige, on distillation, gives a yellowish oil of a flavor 
acrid, pungent, and very enduring; it reddens the blue paper, 
doubtless by free chlorohydric acid. 
The writer further made bichlorure of sulphur prepared cold, 
react on two other carbures of hydrogen, oil of naphtha, and es- 
sence of turpentine, both as highly rectified as possible. With 
the oil of naphtha, the action is lively, and accompanied by a 
marked ebullition; the temperature rises rapidly, and a consid- 
erable ‘quantity: of chlorohydric acid i is thrown off. A black de- 
a yellowish liquid, which, being washed with water, furnished 
a yellowish and glutinous mass, floating on the liquid; it was 
sulphur impregnated with a very volatile oil, rapidly disappear- 
ing from the paper used for straining, and without any sediment. 
This mass undergoing a warm preparation with alcohol, consid- 
erably diminished in bulk, and, after cooling, oily drops gathered 
on the surface. Ether dissolves this species of oil better than 
alcohol ; what remained undissolved by the ether, still betokened, 
on being burned, the presence of a resinous matter ; it was then 
subjected: to the influence of boiling nitric acid, which left a 
globule of sulphur. The washings of the distilled liquid con- 
tained much chlorohydric acid and also some sulphuric acid. 
The deposit left in the cucurbite became blacker and more 
plentiful; it burned like resin, and did not appear to contain sul- 
phur; it is soluble in nitric tecid, sea and by evolving after a
