harsh; gases are generated under the skin, giving the swelling 
a crackling feeling when rubbed. The appetite and rumination 
cease ; the symptoms rapidly become aggravated, the temperature 
rapidly falls, coldness of the surface and extremities, shivering, 
weakness, difficult suffocating breathing, and an imperceptible 
pulse, all betoken approaching dissolution, and ere long with ' 
fixed and staring eye, unable to rise, he becomes convulsive and 
dies in a state of coma. 
POST MORTEM EXAMINATION. 
There is a marked tendency to decomposition, the body is 
usually very much distended from gas, crackling swellings from 
gasses under the skin are found in numerous parts of the body. 
On removing the skin a considerable escape of black, tarry- 
looking blood takes place from the engorged cutaneous vessels, 
which stains the whole surface of the body, giving the skin an 
unusually bloody appearance. 
All the connective tissues are infiltrated by a citron-colored 
serosity. The whole muscular system is pale and soft, except the 
heart, in the muscular structures of which large collections of 
thick black, putrid blood are found. The spleen in most cases is 
very much engorged, its parenchyma is black, soft and friable, 
its covering membrane studded with purple or violet colored 
spots. The lungs are engorged, black and crepitating. The ab¬ 
dominal and pleural cavities usually contain a quantity of 
colored serum. The liver is very soft and nearly bloodless, of a 
pale yellow color resembling boiled liver. The kidneys in some 
cases in a similar condition, and in others engorged and of a 
walnut color. 
In the local form we may have all these post-mortem appear¬ 
ances, and in addition the discolored gangrenous anthrax tumors 
in the quarters or other parts of the body. 
TREATMENT. 
From what has been said of this disease it will readily be 
conceived that treatment will be doubtful in its results, and in
