or papuliie on the skin, whilst in other cases the malady is fully 

 manifested in a very short period. 



Similar to its analogue anthrax, purpura is a disease in which 

 the blood is gravely altered, associated with extravasations, 

 effusion of red coloured serum, preceded and accompanied by 

 constitutional disturbance, languor, debility, sudden elevation 

 of temperature to 104°-106'' F., or even higher, the alternations of 

 temperature being very great. The alternations in the following 

 table are from the clinical report of a case which died at the 

 Collesfe : — 



On the last day there was a copious discharge from nostrils and mouth, 

 kept on its legs till the last, and dropped down dead without a struggle.

The capillaries of the skin and mucous membranes are espe- 

 cially implicated in the congestions, and at all times there is a 

 tendency to gangrene and decomposition of the extravasate, the 

 products of which, being absorbed into the circulation, give rise 

 to septicaemia and death. In some instances, thrombi form in 

 the vessels of the parts more extensively and persistently swollen, 

 and induce sudden death by embolism in the vessels of some 

 vital organ, or a more protracted one by pysemia.
