caffeine. Inodorous arid tasteless; recom- is a transparent solution miscible with 



mended because of its greater stability water in all proportions. Disinfectant 



than iodol. properties equal to Lysol. 



lyORETlN — lODOOXY-CHINOI^IN SULFO- 

 NIC ACID — Iodoform substitute, inodor- 

 ous, yellow; almost insoluble in water and 

 alcohol; forms soluble salts with alkalies. 



Mercury, Gallate and Tannate — 

 Mercuric gallate is prepared b}'- precipi- 

 tating a solution of mercuric acetate with 

 gallic acid, yielding on drying, a brown- 

 ish powder. Mercurous gallate being 

 prepared from mercurous nitrate and 

 gallic acid, yielding a drj', greenish 

 powder. Tannate of mercury — 76.2 gms. 

 tannin is tritulated with 25.7 gms. 5'el- 

 low oxide of mercury and 50C.C, of 

 water; when dr\' is olive green. Both 

 are employed as antisyphilitics, in form 

 of pill, combined with ext. cinchona. 

 Daily total dose o.i to 0.2 gms. 



Malakin — Salic)daldehyd-para-phe- 

 netidin. Closely related to phenacetin. 

 Yellow cry St.; insoluble in cold water; 

 contains about 50% salic3-lalhyde. Em- 

 ployed in muscular rheumatism, neural- 

 gia. Dose 4 to 6 gms. dail}^ 



Pheduretin — A phenol derivative, 

 composition not given ; tasteless white 

 cryst.; insoluble in water. Doses of 0.5 

 to I gni, a powerful diuretic. 



Phenol Chlorine and Bromine de- 

 rivatives — Para-chlorine Phenol, crys- 

 talline ; odor of phenol ; slightly soluble 

 in water. Ortho-brom-phenol is a violet 

 colored liquid. Both employed in the 

 treatment of erysipelas ; i to 2% in oint- 

 ment. 



PixoL — A soluble wood -tar prepara- 

 tion ; 3 parts of wood-tar warmed with i 

 part of soft soap, this gradually mixed 



RESORCYLALGIn — Antiseptic; mad&by 

 the action of potassium resorcylate on 

 antipyrine. Potass, resorcylate . (resor- 

 cinate) made b}' boiling i part re.sorcin 

 with 5 parts KHCO3 and 10 parts water. 

 Resorcylalgin is slightlj^ soluble in water, 

 very soluble in alcohol. Because of its 

 strong acid properties forms soluble salts 

 with .alkaline bases. 



Rubidium Iodide — The Stassfurter 

 potassium salts furnish the source of this 

 base. The iodide is offered as a substi- 

 tute for the' corresponding potassium and 

 sodium salts; inodorous white crystals ; 

 milder taste ; permanent in air ; more 

 soluble than KI ; free from disturbances 

 produced by the potassium base KI. 



Salicylacetol— Because of the de- 

 compos'tion of salol in the system into 

 salicylic acid and phenol, the toxic effects 

 of the latter being often manifested, led 

 to the introduction of salophen ; this 

 splits up into salicylic acid and amido- 

 phenol. This same view led to the com- 

 bination of salicylic acid with a non- 

 poisonous body, acetone. It is made by 

 the reaction between mono-chlor-acetone 

 and soda salicylate :.

 ment of summer diarrhoea. Dose 2 to 3
