may be largelj 7 remedied by a free application of quick lime. 

 This hastens the decomposition of the organic matter and after a 

 year or two, when that has been largely disposed of, the good 

 effects may be expected. 



An important measure is to exclude from fairs, markets, and 

 above all from clay or other dense wet soils into which they might 

 convey the germs, all animals brought from infected soils. 



Disinfection of the buildings where diseased and infected ani- 

 mals have been is an essential measure. Wells and streams receiv- 

 ing the drainage of infected lands must be carefully avoided. 



Diseased animals must be carefully isolated, and all their drop- 

 pings, and products of every kind disinfected. 



The carcasses are best cremated or rendered under superheated 

 steam under pressure. Solution in sulphuric acid may be em- 

 ployed. If none of these are available they may be deeply buried 

 in dry porous soil well apart from any risk of drainage into wells 

 or water supplies. The area occupied by the graves should be 

 fenced in so that no cattle nor sheep can gain access to it, and 

 any vegetation grown on the graves should be burned. The danger 

 of the germs being raised to the surface by soil water or earth 

 worms must be recognized and any consequent evil guarded 

 against. The carcass should not be cut open but buried in the 

 hide, or if the latter is preserved it should be treated with a chlo- 

 ride of lime solution. If a carcass is opened for scientific pur- 

 poses, great care must be taken to avoid the distribution of the 

 bacillus in soil appropriate to its preservation. The meat should 

 not be preserved for human consumption unless it has been cook- 

 ed under pressure at a temperature of 240 F. The object is not 

 to destroy any poison which would be fatal to man, but rather to 

 prevent the spread of the spores on new soil and the extension 

 of the area of infection. 



The reduction or prevention of sudden plethora was formerly 

 availed of to lessen the number of victims and it is well to still 

 bear in mind that this has an appreciable though limited effect. 

 As a means of reducing plethora a free bleeding was resorted to 

 when the period of yearly prevalence approached, and no less 

 when the disease had already appeared in a herd. I can mention 

 an instance in which infection was carried on the fleam from the 

 first animal bled(the sick one)and caused the fatal infected swelling
