tion. A solution of galls in ether is the most delicate test 

 of the presence of salts of iron. 



As an astringent, galls possess all the properties which can 

 be expected from medicines of an astringent character; they 

 are, nevertheless, seldom used as internal medicines. They 

 enter the circulation, but previously produce a primary styp- 

 tic influence upon the stomach, which, when the dose of the 

 medicine is large, greatly incommodes the organ ; hence, 

 when internally administered, they are combined with other 

 substances, usually with aromatics. For internal exhibition, 

 the powder is certainly the best form of administering the 

 medicine ; the dose of galls may be from ten grains to one 

 scruple, which may be given twice or thrice a day. They 

 are frequently ordered in the form of gargles and injections ; 

 and an ointment formed of galls in fine powder, with eight 

 parts of simple ointment and a small proportion of powdered 

 opium, is a useful application to blind piles. 



It is almost unnecessary to remark, that galls ought not to 

 be powdered in an iron mortar. 



TINCTURA GALL.E, L. D., U. S. TINCTURA GALL ARUM, Ed. 

 Tincture of galls. Take of galls bruised foitr ounces ; diluted 

 alcohol two pints; macerate for fourteen days, express, and 

 filter through paper. 



This tincture may also be prepared by thoroughly moisten- 

 ing the galls, in powder, with diluted alcohol, allowing it to 

 stand for twenty-four hours, then transferring it to a percola- 

 tor and gradually pouring upon it diluted alcohol, until two 

 pints of filtered liquor are obtained. U. S. 



The London College directs five ounces of powdered galls, 

 two Imperial pints of proof-spirit, and maceration for seven 

 days ; the Dublin, five avoirdupois ounces of the galls, two 

 Imperial pints of the spirits, and maceration for fourteen days. 

 The Edinburgh College takes the same quantity of materials 

 as the London, and prepares the tincture either by digestion 

 or percolation.
