140 CONTAGIOUS DISEASES OF DOMESTICATED ANIMALS. 



{h) Quarantine of uewly bought animals for five or six weeks is au 

 important i)recaution. 



(/) Posting notices of infection at the entrance of infected zones or 

 farms. 



{]) Handhills and instructions for tbe people in or near the infected 

 area. 



(A) Surveillance with verj* frequent visitatiou by ipspectors and police. 



Preventive medication for animals exposed to infection may embrace 

 setons medicated with hellebore, and antiseptics, such as ferric sulphate, 

 alkaline sulphites, carbolic acid, borax, tar, chlorine. 



All restrictions may be removed forty days after the last case of disease 

 has been disposed of and the place and objects disinfected. (This is en- 

 tirely inconsistent with what he has already advanced as to occult cases, 

 chronic cases, and long periods of incubation which could so easily ex- 

 ceed twice the forty days required. It is another iudication of an aim 

 at restriction rather than extinction.) — J. L. 



If carcasses have to be removed, this should be done in wagons with 

 close joints, so that nothing shall escape, and drawn by horses under 

 police supervision. The carcass and diseased products may be deeply 

 buried, burned, rendered, or dissolved in sulphuric acid. It is often 

 utilized for food, but this should be prohibited when the lung lesions 

 are very extensive, advanced, and comi)licated by gangrene, when there 

 is ulceration of the bowels, or when the tlesh is flaccid, decolorized, 

 ecchymosed, or the seat of serous infiltration. The sldn ma^" be sent to 

 the tannery after steeping a length of time in milk of lime, or solution 

 of chloride of lime, or zinc, or carbolic acid. 



Disinfection of stables demands washing, scraping, and the thorough 

 application of liquid disinfectants. Manure, fodder, and litter should 

 be burned or disinfected, or the latter may be fed to horses. Horses 

 and other animals that have been with'diseased cattle should have their 

 surface cleaned and disinfected by an antiseptic solution. 



LEBLANC'S VIEWS. 



Leblanc sought to throw doubt on the diagnosis of lung plague dur- 

 ing life, on the specific character of the lesions seen in the carcass, and 

 on the value of inoculation. Many inoculated animals have already had 

 the disease and are protected by that ; cases already infected before 

 inoculation have the disease aggravated by the operation ; the poison, 

 and therefore the disease, is preserved and perpetuated in certain dis- 

 tricts by the i)ractice of inoculation ; inoculation is no certain prophy- 

 lactic, for just as in the same lung we see chronic lesions side by side 

 with the acute, implying a second attack, so may an attack follow a 

 successful ino(udation : and finally, the same measures of se<;regation 

 and slaughter usually employed with inoculation would be successful 

 Avithout that operation.
