if the proportion of sugar employed be too small, it will promote in- 
stead of retarding the fermentation of the articles it is intended to 
preserve. Molasses or treacle is a very impure syrup, which remains 
after refining the sugar. Treacle is applied to many domestic econo- 
mical purposes. Sugar candy is used by persons laboring under 
hoarseness and coughs; the violence of which it contributes to re-

¢ Suptmmep Surpuur. Flowers of Sulphar. = fi ae 
~*Sulphurs is a simple, inflammable substance, found in nature 
nearly pure. It is the produce of volcanic countries. 
Pure sulphur is of a light yellow color; is insipid; has a faint 
smell, when rubbed or heated, is very fusible and volatile ; and, when 
qanted in atmospheric air, burns with a blue fame and suffocating 
umes. 
Flower of sulphur loosens the belly and promotes insensible per- 
Spiration ; it seems to pass through the whole habit, and manifestly 
transpires through the pores of the skin, as appears from the sulphu- 
rous smell of persons who have taken it, and from silver in their 
pockets imbibing a blackish cast. Itis a celebrated remedy against 
cutaneous diseases, both given internally and applied externally. It 
has likewise been recommended in coughs, asthmas, and other disor- 
ders of the breast and lungs; and particularly in catarrhs of the 
chronic kind. But it is probable that the benefit derived from it in 
these cases, is principally owing to a determination to the surface, 
_ and to its operation asa gentle laxative. And with this intention it is 
frequently used with great advantage in piles, and in many other dis- 
€ases in which it is proper to keep the belly open. The dose is two 
or three drachms, in honey or molasses,

This acid is formed from the combination of sulphur with oxy- 
gen to the point of saturation. It is obtained by the combustion of 
sulphur, The sulphur, reduced to powder, is mixed with from one 
eighth to one tenth of its weight of nitrate of potash, by which its 
_ ¢ombustion, when began, can be continued, withou tthe free access of 
_ atmospheric air. It is thus burnt ina large leaden chamber ; the 
sulphuric acid, which is slowly formed, is absorbed by water placed 
im the bottom of the chamber; the acid liquor is concentrated by ex- 
Posing it to heats in glass retorts, and the pure sulphuric acid is

_ Ms-specific gravity is 1850; when pure, it is colorless and transpa- 
ent. It strongly attracts water, which it imbibes from the atmos- 
Phere very rapidly, and in large quantities, if suffered to remaim in 
An open vessel. If it be mixed with water it produces an instanta-
