Upon the basis of a comparison of the results of Koch's 

 observations with those of numerous subsequent investiga- 

 tors Schimmelbusch arranges the disinfectants in accord- 

 ance with the time in which they destroy anthrax-spores, in 

 the following order : 



Mercuric chlorid, 

 lodid, chlorin, and bromin, 

 lodin trichlorid (Behring), 

 Kresol rendered soluble by addition 

 of sulphuric acid (C. Frankel), 



destroy anthrax -spores within 

 twenty-four hours. 



Chlorinated lime, five per cent., 



Formic acid, 



Quinin, one per cent., with hydro-

in the thousand, r J the s P orcs in about 

 Hydrochloric acid, two per cent., 

 Ether destroys the spores in about thirty days. 



III. Anthrax-spores are still not destroyed after the lapse of a month in absolute 

 alcohol, distilled water, chloroform, glycerin, benzoic acid, ammonia, 

 concentrated solution of sodium chlorid, five per cent, potassium 

 chlorate, alum, borax. 



The figures obtained experimentally, however, constitute 

 no trustworthy index of the practical utility of an agent. 

 For practical purposes the greater or lesser solubility of a
