parts, and give exit to a foul smelling, yellowish, or dark 

 red fluid. Large sloughing ulcers remain behind. The 

 surrounding parts are congested and swollen by extension 

 of inflammation. Saliva mixed with, the putrid serous 

 discharges pours profusely from the mouth. Respiration 

 is considerably interfered with, fever runs high, and 

 debility early sets in and increases rapidly. The pulse 

 very soon becomes small, double, and scarcely perceptible. 

 Sometimes recovery occurs, vv^hen there is considerable 

 sloughing of the tissues of the tongue, and the animal 

 has to be nursed through, a long period of convalescence. 

 Generally death takes place early, and post-mortem 

 examination shows general anthrax lesions besides the local 

 morbid conditions. 



Treatment — Care must be taken lest the discharges 

 from tbemouthfall on an abraded surface. Cases of this kind 

 ought to be isolated. Free incisions should be made into 

 the gangrenous organ, and antiseptic applications be used 

 locally. The strength must be husbanded in every possible 

 manner, especially the patient must receive soft nutrient 

 food. Where the swelling of the throat threatens suffo- 

 cation tracheotomy must be performed. 



Oharbonous gangrene of the lungs is described by Pro- 

 fessor Williams as a secondary anthracic condition. He 

 mentions it as appearing like a relapse on about the tenth 

 day, the breath becoming very foetid, the respiratory 

 movements muck accelerated, and the animals sinking 

 rapidly, the lungs after death being gangrenous, emphy- 

 sematous, and loaded with black, tarry, and decomposing 

 blood.

 Inflammatory Fever, 8fc. — This is an anthracoid disease, 

 but is probably not anthrax, not due to Bacillus anthracis. 



It used to be considered ^' external or symptomatic 

 charbon,'^ an endeavour of nature to throw off anthrax 

 poison from the system, and was by some thought rather 

 a favorable condition ; but quite recently the identity of 

 splenic fever and black quarter has been successfully called
