Iodine Tincture. — Popiel (Ph. Ztsch. f. 

 Russl. ). after numerous experiments has shown 

 that the preservation of tincture of iodine in the 

 dark or in amber bottles is entirely unneces- 

 sary, as the products of decomposition (hydri- 

 odic acid, iodoform, iodethyl), caused by the 

 action of light, again suffer decomposition with 

 the separation of free iodine. The use of im- 

 pure alcohol, particularly such as contains fusel 

 oil, causes rapid decomposition with the forma- 

 tion of iodine substitution products. 



Alpha Guaiacol. — A sympathetic, crystalized 

 guaiacol prepared by Frere, Champigny & Cie., 

 of Paris. 



Ferrol. — According to Chemist and Druggist 

 it is a purified petroleum extract, recommended 

 by the Ferrol Company as a substitute for cod 

 liver oil. 



New Morphine Reaction. — Bruylant {Anna!, 

 de J-har., i8g$, ) recommends that a sample of 

 morphine or its salts be warmed with a few 

 drops of pure sulphuric acid on a water bath, 

 then adding a drop of Froehde-Buckingham's 

 Reagent (0,01 Gm, Ammonium molybdate to 

 i Cc. H 2 S0 4 ) whereby a bright green color is 

 produced ; this remains unchanged for some 

 time. This reagent possesses the advantage that 

 several reactions may be carried on different 

 conditions. For example : the morphine is dis- 

 solved in two drops of concentrated sulphuric 

 acid on a watch glass, than by means of a glass 

 rod a trace of the solution is removed and stir- 

 red with a few drops of Froehde's Reagent on a 

 porcelain surface, whereby the well known 

 purple color reaction is produced. The sul- 

 phuric acid solution contained in the watch 

 glass is warmed on a water bath and a fresh 

 portion of Froehde's solution added, whereby a 

 green color is produced. To this green colored 

 solution a few grains of saltpetre are added, and 

 after stirring, a red color results, which after a 

 time changes to a yellow. The following table 

 shows the various color reactions produced by 

 the different opium alkaloids with the above 

 reagents : 



Alpha Creosote. — A product prepared by 

 mixing the various constituents, such as occur 

 in normal creosote, in such proportions that it 

 contains 25 per cent, of crystalized guaiacol. 



Anti-Bacillare. — A mixture containing cre- 

 osote, tolu-balsam. glycerin, codein and sodium 

 arsenate, recommended as a remedy against 

 phthisis, 



Antistreptococcin. — A serum preparation; an 

 antitoxin against erysipelas, prepared by Dr. 

 Marmorek, of the Pasteur Institute, Paris. 

 Obtained from the cultures of the erysipelas 

 bacillus (streptokokken). 



Chin olinr hod anid. — A new antiseptic, which 

 possesses the antiseptic properties of both mer- 

 curic chloride and carbolic acid, being at the 

 same time entirely free from any toxic effect. 

 A 0.3 per cent, solution destroys the cholera 

 bacillus in one minute, while during the same 

 time the diphtheria bacillus is destroyed by a 

 0.9 per cent, solution. In treatment of gonor- 

 rhoea a 1 per cent, solution produced effective 

 results. 



Diacetanilid. — Prepared by heating phenyl 

 mustard oil with acetic acid, or by heating 

 acetanilid with glacial acetic acid at a tem- 

 perature of 200 to 250 C. In medicinal effect 

 it is more powerful than acetanilid. 



Gallicin. — The methylether of gallic acid, in- 

 troduced by Messrs. Sandy & Co., of Basel. 

 Prepared by heating a solution of gallic or tan- 

 nic acid in methyl alcohol with sulphuric acid. 

 Its constitution [C 6 H 2 COOCH 3 (OH) 3 ] re- 

 minds one of Resorcin and Pyrogallol; it is, 

 however, non-toxic. 



Copperhaemol. — A compound of haemoglobin 

 and copper (C 648 H 1030 N 17s FeCu 5 S 2 O 177 ) pre- 

 pared by E. Merck. It is entirely absorbed by 

 the intestines without producing any disturb- 

 ances. Dose, 0.5 Gm. 



Lai/an. — A crude borneol, probably identical 

 with the Ngaicamphor of the Blumea balsami- 

 fera. It forms a thick paste, which is employed 

 by the Chinese as an outward application for 

 the relief of headache.
