and internal temperature; a bloody or sero-sanguinous fluid es¬ 
capes from the nostrils and anus or is mixed with the faeces. 
The symptoms above described are present but in a more chronic 
form, and its course may be protracted for twenty-four hours. 
Bollinger describes an intermittent variety, in which irregular 
remissions and intermissions may be observed lasting a few hours, 
often six, twelve or twenty-four hours. The breathing during a 
paroxysm becomes labored and gasping (dyspnoea); such mucous 
membranes as are visible grow cyanotic; the extremities cool; 
the convulsions become violent; opisthotonos and convulsive con¬ 
tractions of the muscles of the eye are observed, so that only the 
white of the eye remains visible. The animal grows very weak; 
can no longer keep itself upon its feet; the temperature falls be¬ 
low the normal standard ; the extremities become cold ; the pu¬ 
pils dilated to their utmost, and death follows in the form of 
asphyxia, generally twenty-four, thirty-six, or forty hours after 
the first appearance of the symptoms. 
The third form usually described as anthracoid erysipelas, al¬ 
so as black quarter” or u quarter ill,” differs only in there being 
a localization of the disease in various parts of the body; 
usually, however, even in this variety yellow serous exudates 
take place in all the connective tissues, the internal vascular or¬ 
gans are usually enlarged and engorged with the black tarry- 
looking fluid. In the form known as black quarter , which is not 
uncommon in many parts of this country, it usually occurs in 
young thriving stock, in which no indications are observed until 
the owner’s attention is attracted by one or two being found 
dead. Most cases afford opportunities for studying the symp¬ 
toms, and many even for applying treatment. In this case we 
have all the symptoms of septic poisoning, dilated pupils, dull¬ 
ness, the head being carried low, muzzle dry, pulse quick, tem¬ 
perature high, 105° to 107°, stiffness or inability to move; he 
may be found supporting himself against the fence or lying down 
with the head thrown back to the flank unable to rise; local 
swellings are found in different parts, such as the quarter, back, 
neck or sub-thorax; the swelling at first is hot and tender, but it 
soon becomes cold, the skin and hair over the part feel dry and
