so that the fluid after sixteen days contained as much vibrio-life as the 

 standard putrid albumen : — 



Cbloride of aluminium, sulphurous acid and prussic acid. 



The fifth class contains those compounds which acted injuriously at first, 

 destroying the locomotive power of most of the vibrios, but which after- 

 wards permitted the vibrios to increase more rapidly than in the standard 

 albumen-solution : — 



Bleaching-powder, bichloride of mercury, chlorine-solution, caustic soda, 

 acetic and nitric acids, sulphate of iron, and the sulpho-carbolates of potash 

 and soda. 



The sixth class contains those compounds which exercised no action on 

 the animalcules, either at first or after sixteen days : — 



Arsenious acid, common salt, chloride of calcium, chlorate of potash, 

 sulphate of lime, bisulphite of lime, hyposulphite of soda, phosphate of 

 lime, turpentine, and pepper. 



The seventh class includes those substances which favour the production 

 of animalcules and promote putrefaction : — 



Lime, charcoal, permanganate of potash, phosphate of soda, and ammonia.
