MISCELLANY. 
Chloruret of Lime in Gonorrhoea. — Professor Graefe, of Berlin, states 
that he has succeeded with this article where copaiba and cubebs have 
failed. He used it in pills and injection. The pills are made as follows : 
B Chlor. calc. gi. 
Extr. opii, gr. ix. 
Mucilag. Gum Arab. q. s. 
Of this, fifty four pills are to be made. At first, one is to be taken every 
two or three hours, and the dose gradually increased till eight, ten, or 
twelve are taken every hour. The injection is made by dissolving gr. xxiv. 
in water ^vj., adding vin. opii £ss.

Indigo in Epilepsy. — Dr. Ideler, of Berlin, asserts that he has obtained 
beneficial results from the administration of powdered indigo in epilepsy. 
He administers it in the following manner: 
R Powdered indigo, ^ss. 
Aromatic powder, gss. 
Syrup, q. s. to make an electuary. 
This is at first to be taken in two days, and afterwards in one. The 
dose of indigo may be increased to six or eight drachms a day. Accord- 
ing to the author, the first effects of the remedy are nausea and vomiting; 
sometimes it produces a diarrhcea, which soon ceases, and is followed by 
constipation ; the urine becomes of a brown colour.

Gallic Acid. — Dobereiner says that gallic acid may be rapidly prepared 
by mixing a concentrated decoction of nutgalls with a little acetic acid, to 
decompose the gallate of lime, agitating with ether, which takes up most 
of the gallic acid, evaporating this solution to obtain the gallic acid, which 
is thus procured in a very short time, in the form of small colourless 
prisms. Pharm. Tech. Rath. 
Mode of detecting some Organic Acids. — H. Rose has discovered that 
tartaric, paratartaric, citric and malic acids may be readily detected in the 
following manner : they are to be dissolved in as small a quantity of water 
as possible; to this solution an excess of completely saturated lime water 
is to be added. 
Tartaric and paratartaric acids form precipitates in the cold state. That 
produced by tartaric dissolves completely in a small portion of solution of 
ammonia, whilst the paratartaric remains insoluble. Both acids are 
readily distinguishable by treating their solution with sulphate of lime ; 
after some time lime is deposited in that of paratartaric, whilst that of 
tartaric is not affected. 
A solution of citric acid yields no precipitate with lime water in a cold
