ANTHRAX

no apparent diminution in the extent of the disease. It was 

 followed with Pasteur's vaccine with very satisfactory results. 

 It has not been demonstrated, however, that the sudden check 

 m the spread of the disease was not a coincidence rather than 

 the effect of the blood. A single experiment in cattle to test 

 the efficiency of the heated blood in protecting against anthrax 

 inoculation gave negative results. The same held true for ex- 

 periments with guinea pigs. Loeffler has already pointed out 

 the fact that small experimental animals are not readily 

 immunized to anthrax. 



The disposition of dead animals in an outbreak of anthrax is 

 a matter of much importance. In all cases they should be burned 

 if possible, if not, they should be buried deeply and thoroughly 

 covered with quick lime before the dirt is replaced. The ground 

 over the place where they are buried should be fenced in to 

 prevent other animals from grazing over it and the surface 

 should be burned annually for some years to destroy spores 

 should they be brought to the surface. In all cases the well 

 animals should be removed from the barns or yards containing 

 the sick ones and from pasture lands on which the sick became 

 infected. The temperature of the supposedh' healthy and un- 

 infected animals should be taken morning and evening for from 

 one to two weeks after they are removed and all of those show- 

 ing an elevation of temperature should be isolated. Bj^ careful 

 isolation and safe disposition of the dead animals the spread of 

 the disease can be checked. Animals do not, as a rule, spread 

 the virus when the first sj'mptom (rise of temperature) can be 

 detected. All infected stables and yards should be thoroughly 

 disinfected.
