been salted for a month and then smoked for fourteen days may still 
contain the bacillus of rothlauf in a living condition, as shown by in- 
oculation experiments. It was not until about six months after smok- 
ing that the bacillus failed to give evidence of vitality. 
Thymol.—A. five-per-cent solution in alcohol does not destroy 
anthrax spores in fifteen days, but the development of these spores 
is retarded by a solution of 1:80,000 (Koch). The anthrax bacillus 
and staphylococci fail to grow in culture media containing 1 : 3,000 
(Samter). The tubercle bacillus is destroyed by contact with thy- 
mol for three hours (Yersin). Thymol has about four times less 
germicidal power than carbolic acid (Behring). Antiseptic in the 
proportion of 1: 1,340 (Miquel). 
Tobacco: Smoke.—Tassinari found that tobacco smoke restrains 
the development of bacteria, and that certain species failed to de- 
velop after exposure for half an hour in an atmosphere of tobacco 
smoke—spirillum of cholera and Friedlander’s bacillus.
