phenocoll, which has been employed 

 chiefly as hydrochloride. The after effects 

 produced by the soluble salts of this base 

 are absent in this, probably because of 

 its insolubility ; mild and reliable anti- 

 pyretic, anti-neuralgic ; in doses of i to 

 2 gms. several times daily. Specific in 

 influenza. 



SaLUMIN — AIvUMlNlUM SALICYLATE — 

 Recommended in catarrhal affections. 

 — Riedel. 



Sedatin — para-valeryl-amido-phene- 

 tol. A patented sedative made by re- 

 action between para-mido-phenetol and 

 valeric acid. Dose not given. 



Sodium Peroxide — Employed as 

 bleaching and oxidizing agent; yellowish 

 powder, very soluble in water. In con- 

 tact with water oxygen is disengaged; 

 with dilute acids it forms hydrogen pe- 

 roxide, of course the liquid must be well 

 cooled. Contains 20% active ox^'gen. 



Sodium Sulfocaffeate — -Nasrol — 

 Since the introduction of the sulpho. 

 group decreases the medicinal potency in 

 phenol groups, the same was tried here 

 with success. Bitter, crystalline, slight- 

 ly soluble in cold water; non-toxic, does 

 not irritate the stomach. Solutions con- 

 taining more than 5% are not stable. 

 Besides above soda, lithium and stron- 

 tium salts are prepared. A powerful 

 diuretic. Dose i gm. in capsule. 



Tannal — aluminium tannate — Ap- 

 plication like unto that of Salumin. — 

 Riedel. 



Thuiret — CgH^NjS, — A sulphurated 

 antiseptic. Oxydatious product of phenyl- 

 dithiobiuret. Inodorous crystalline pow- 

 der, insoluble in water; soluble in alco- 

 hol and ether. Has the property of 

 giving up sulphur readily (statu nascendi) 



upon which its disinfectant properties 

 depend. As best adapted salt of this 

 basic thuiret, is the para-phensulfonate, 

 a yellow crystalline inodorous powder, 

 which can be employed in solution as 

 well as dry antiseptic. 



Thiofobm — Basic dithio-salicylate of 

 bismuth. A substitute for iodoform, in- 

 odorous, yellow-brown, insoluble powder. 

 Advantages claimed, being inodorous 

 and non-toxic. 



Thymacetin — A crystalline solid; de- 

 rived from thymol, in which an ethyl 

 group is substituted for the H of hy- 

 droxyl, and an acetylated amido group 

 for a H in the nucleus. Employed as 

 an anti-neuralgic. 



TOLYLANTIPYRINE DERIVATIVES-The 



chlorhydrat, isonitroso, monobromo and 

 monoiodo. These are all less soluble than 

 the corresponding antipyrine derivatives, 

 like tolypyrine itself, being only soluble 

 12 parts in 100 of water. 



Tricresol — A purified mixture of the 

 three isomers of cresol; soluble to extent 

 of 2.5% in water, forming a neutral solu- 

 tion. A I %■ aqueous solution is equal in 

 disinfecting power to a 3% aqueous 

 phenol solution. 



Xylenol Salols — Made by the action 

 of dehydrating agents on a mixture of 

 salicylic acid and xylenol, yielding ortho- 

 meta and para salicylate of xylenole. 

 Physically and chemically resembles the 

 well-known salols ; insoluble in water, 

 alcohol and ether; without any noticeable 

 taste or odor. Employed as intestinal 

 disinfectants. 



Zinci-boricum — Prepared by mixing 

 solution of 5 parts zinc sulphate in 50 

 parts water, with solution of 4 parts 

 borax in 100 parts of water.
