Pixene. — This is a preparation which is said to he a solution of 
the principles of wood-tar. It has a strong empyreumatic odour, and 
forms an emulsion with water. Undiluted pixene seems to destroy 
the anthrax spores if allowed to act on them for twenty-four hours. 
A 10 per cent, solution in water, acting on the spores for twenty- 
four hours, delayed gowth, but it was ultimately active. 
In this case, as in all the tar products, it was found necessary to 
be very careful to completely free the “ fluff” from the disinfectant. 
In my earlier experiments with, pixene, when I did not wash the 
spores sufflciently, I gave a higher value to it than it really pos- 
sessed. This was owing to the inhibitory power which small 
quantities of the tar products exercise on the growth of anthrax 
when actually present. 
^^Sanitas” Fluid. — The fluid is said to contain peroxide of 
hydrogen, thymol, camphoric acid, and terebene. 
Spores soaked in the fluid for twenty-four hours afterwards grew 
freely when placed on suitable soils. 
Sanitas Emidsion. — The spores placed in sanitas emulsion were 
delayed in growth, for there was no development for twenty-four 
hours. In forty-eight hours there was a feeble growth. Ultimatel}" 
it was luxuriant. 
Sanitas Oil. — This gave entirely similar results. 
Sanitas Powder had no influence whatever on the growth of 
anthrax. 
Morgans Fluid, which contains sulphate of copper and zinc, 
with other ingredients in solution, was experimented with in the 
diluted and undiluted form ; but in neither did it seem to have the 
slightest influence on the life of the spore. 
Sidpliate of Iron, which has been recommended to disinfect 
typhoid excreta, was experimented with in like manner. A 
saturated solution was made by boiling a large quantity with 
water, and then allowing it to cool. 
Here again in no case was any destructive influence on the life 
of the spores observed. 
Sulphate of Copper was also dissolved, and made of strengths 
from 5 per cent, up to saturation j but the spores were in no way 
attacked, although allowed to remain in the liquid for twenty-four 
hours.
