deep and quiet sleep in individuals who 

 were not affected by other hypnotics. 

 Its solution is very bitter ; best given in 

 capsules. 



Chloroform — Anschiitz proposed the 

 preparation of a pure chloroform, based 

 on the fact that it combines with salicy- 

 lide (dehydration of salicylic acid) form- 

 ing an insoluble cryst. compound : 



fc6H,<^^] 2CHCI3 with 33% chloro- 

 form; stable when kept in closed vessels; 

 on vv^arming chloroform is liberated. 



Creosotal — A mixture of carbonates 

 of guaiacol and homologues found in 

 creosote; is prepared by passing a current 

 of phosgene (CO Clj) through a solu- 

 tion of sodium creosote. A viscous liquid, 

 inodorous ; insoluble in water, glycerin 

 and dil. alcohol. Substitute for creosote. 

 Dose 10 to 20 gms. Does not disturb the 

 digestive functions ; in the intestines it 

 splits up into creosote and COo. 



Di-iodoform-tetraiodoethylenk- 

 C2I4 — Of all iodized antiseptics this con- 

 tains the highest per cent, of iodine; no 

 odor, yellow crystals. 



DuLCiN OR Sucrol — Para-phenetol- 

 carbamide. It is closely related to Urea, 

 in which the H in one of the aniodo 

 groups is replaced hy the phenetidine 

 residue, thus :

A white crystal, solid ; soluble in 800 

 parts cold and 50 of hot water and 25 of 

 alcohol. Because of its intense sweet 

 taste, being 200 times that of cane sugar, 

 offers a substitute for this carbohydrate. 

 In large doses does not produce injurious 

 effects ; and in long continued use, does 



not create the dislike usually caused by 

 saccharin. 



FoRMANiLiD — CeHgNHCOH. Pris- 

 matic crystals, very soluble. In hy- 

 podermic injections of 3% solution acts 

 as an anaesthetic. A 20^0 solution, 

 when applied to the tongue produces 

 prolonged numbness. Sprinkled upon 

 bleeding wounds, it stems the flow of 

 blood batter than antipyrine. As .an an- 

 odyne the maximum dose is o 5 gm. 



Formalin — Formic aldehyde being a 

 well-known powerful anti-bacterial, has 

 led to its introduction by the Schering 

 factory; is an aqueous 40% solution. 

 Owing to the volatility of formic aldehyde, 

 it is given off at ordinary temperature. 

 In dilution of i to 20,000 it destroys the 

 anthrax bacillus in one hour, excelling 

 all disinfectants and equal to sublimate; 

 preferred to this because of its non-pois- 

 onous properties. Valuable for disin- 

 fecting instruments, sponges, sick rooms, 

 etc., a \% solution best adapted. Em- 

 ployed in form of dry powder, contain- 

 ing 20%; the absorbent material being 

 infusional earth. 



Gallanol — An anilid of Gallic acid; 

 obtained by heating aniline and tannin 

 together. Forms colorless crystals; bit- 

 ter taste; very slightly soluble in cold 

 water, more so in hot water and alcohol. 

 Employed as a substitute for pyrogallol 

 in psoriasis, and has the advantage of 

 being non-poisonous and non-irritating. 

 In ointment 10 to 20%. 



Iodine Eugenol — Obtained by treat- 

 ing an alkaline solution of eugenol with 

 iodine. 



Iodo-caffeine — A compound of caf- 

 feine with sodium iodide; unstable, hot 

 water is sufficient to decompose it.
