‘ No. 24.—Acipum SuLpHuricum AROoMATICUM.— 
Aromatic sulphuric acid. Elix. of vitriol. 
Cabinet specimen, Jeff. Coll. No. 23. Sie 
This preparation contains ginger, cinnamon, and alcohol. It 
is erroneously considered to be an impure kind of ether, 
but is no more than a solution in alcohol of the acid and 
the above aromatics—it is absurdly denominated a finelure, 
in the Phar, U. S. 
Quatitizs. Limpid; of a mahogany or red-brown colour ; 
odour peculiar and aromatic ; taste gratefully acid. Dose 
as in No. 23, in water or chamomile tea. May be used in 
all the affections i in which No. 23 is employed. It is, in- 
deed, the common way of giving sulphuric acid. The dose 
itis may be repeated three or four times a day. It is now com- 
monly used in the mixtures of sulphate of quinine, to add 
excess of acid. These mixtures are therefore aromatic 
alcoholic super-sulphates of quinine. 
» No. 25.—Acrpum TartTaricum. Tartaric acid. 
Cabinet specimen, Jeff. Coll. No. 24. 
— Quaxrries. When crystallized, is white, semi-transparent, ee 
persistent in the air, inodorous, and very acid to the taste; 
primary form of crystal, an oblique rhomboid prism; melts 
if heated above 212° F.; boils at 250°, without losing its 
whiteness ; readily soluble in water, the saturated solution 
not being liable to spontaneous decomposition ; forms tar- 
trates, with alkalies, earths, and pcrecar aie sown readily — 
saturates alkalies, like citric acid ;.carelessly made, con- 
tains sulphuric acid, which can be acmeed by adding: 
muriate of barytes to the solution, when a precipitate, in- 
soluble in excess of muriatic acid, will be thrown down. _ 
This acid exists in prey en eS othe ob- 
tained from red wines—in tartarum album, or white 
which is an impure super-tartrate of potass, gy seo 
white wines ; it is the essential salt of the gra 
during the fermentation of the wine, poor <n 
ern countries, where the fruit does not ripen Raccctae 
It is contained in common cream of tartar—in salute’ tar- 
tar, which is a tartrate of potass—in Rochelle salt, which 
is a tartrate of potass and soda—in tartar emetic—in the 
composition of one of the papers of Seidlitz powders. It 
ete, ened in engetaey aye insolutian: with large quan- 
tities of water. _
