oil. This, upon examination was found 

 to consist chiefly of d-linalool. The 

 presence of a fatty acitl and a very small 

 amount of a nitrogenous body was also 

 ascertained. 



The Detection of Very Small Amoonts 

 of Nitrites in Potable "Waters. 



For this purpose L. Rosenthaler and 

 V. Jahn recommend the indol reaction 

 of Dane. 



The reagent employed consists of a 

 solution of 0.O2 grammes of synthetic 

 indol in 150 cc. of 95% alcohol; from 

 3 to 5 cc. of this reagent, together 

 with 1 cc. of oO^f' sulphuric acid, are 

 added to 100 cc. of the suspected 

 w^ater. In the presence of nitrites, a 

 blue-red color appears after the lapse 

 of one minute. In presence of minute 

 traces of nitrites the color change will 

 be pale violet, and its appearance will 

 be delayed. Experiments have shown 

 that the presence of ammonium salts, 

 iron, manganese or nitrates do not inter- 

 fere with the reaction. In total absence 

 of nitrites the reaction is negative, even 

 in presence of the substances named. 

 The reagent is fairly stable. After a 

 lapse of four months the reagent was 

 still found to be reactive. 



NEW REMEDIES. 



Chinocol. Under this name tablets are 

 marketed, each of which contains 0.15 

 gm. of quinine sulphoguaiacolate and 0. 1 5 

 gm. of fluidextract of piscidia erythrina. 

 These tablets are claimed to of value in 

 the treatment of tuberculosis. 



Eudulsan is the name given to tablets 

 claimed to be of value in the treatment 



of the various forms of diabetis. C 

 Mannich has endeavored to ascertain the 

 composition of these tablets, but has not 

 been able to isolate any constituent 

 which might be said to possess properties 

 able to combat the disease for which the 

 tablets are recommended. Mannich 

 fmds plant extracts to which alx)ut 30% 

 of inorganic material, consisting mainly 

 of magnesium silicate, has been added. 

 Lecithin was also found to be present. 



GJanduitrin-Tono^cn contains in each 

 cc. 0.2 gm. extract of pituitory gland, 

 and 0.0005 gm. of adrenalin. The pre- 

 paration is claimed to be useful in the 

 treatment of asthma. 



Atoxikokain according to Dr. Hans 

 Brun is to be considered as the fol- 

 lowing : p-amino-benzoyl-di-ethyl-amino- 

 ethanol-chloral-hydrate. It therefore is 

 j)ractically identical with novocaine. 



Sapofen. This name is given to solu- 

 tion of tar-oil in resin soap, which 

 when mixed with water turns milky. It 

 is claimed to be a non-poisonous, non- 

 irritating disinfectant. In 3 to 5^^ 

 solutions, it is said to possess the 

 properties of a deodorizer and dis- 

 infectant. It may be described as a 

 clear-dark-brown liquid, possessing a 

 tarry odor. Its specific gravity is 1.030 

 to 1.050. Sapofen mixes readily with 

 equal parts of ether or petroleum benzin. 

 and is miscible with alcohol in any pro- 

 portion, forming practically clear .solu- 

 tions. 5 parts of sapofen mixed with 95 

 parts of water produces a milky solution, 

 possessing a mildly alkaline reaction. It 

 contains about 20% of coal tar con- 

 stituents.
