with, and fjenerally succeeds wounds of the extremities m 

 horses debilitated oy oard work, bad keep in young plethoric 

 animals, or in those tainted by glanders, animal malaria^ or 

 septic infection. 



St/inntoms. — In an indefinite period, but generally about 

 the tliira or fourth day after the infliction of an injury —more 

 particularly if such be on a depending -part of the body — tlia 

 ftkin in the immediate neighbourhood of the wound is found 

 swoUen, smooth, shining, hot. tender, and painful ; the swelling 

 gradually extends from the wcurd, embracing in some instances 

 the whole superficies of a limb in the course cf a few hours. 

 The swollen surface pits on pressure wnere muoh areolar tissue 

 is found but ^hore the subcutaneous tissues aie hard and firnv 

 the impression of the finger is not so well defined. 



Vesication sometimes occurs, but this is not a constant 

 symptom, and is succeeded by some amount of desquamation. 

 Snore particularly at the flexuies of the joints. Uhe local 

 manifestation of the erysipelatous inflammation is accompanied 

 by s(5tae degree of constitutional disturbance ; the pulse becomes 

 quick, rigors are present , the animal is " fevered," as it is com- 

 monly expressed, loses its appetite, and pain is manifested by 

 lameness if the disease be in a limo. 



PULEGMOVOUS EKYSIPEL-VS. 



This is a much more violent form than the (edematous, and 

 IS expressed by a great amount of constitutional disturbance, 

 partaking of a typhoid character : the tendons and Hgamentous 

 sti-uctures, the fasc'a of adjacent muscles, as well as the skin 

 and subcutaneous areolar tissue, become involved in the inflam- 

 mation ; the pain is excessive, the swelling is hard, tense, and 

 occupies a large extent of surface. In & variable period, 

 purulent collections form in the subcutaneous areolar tissue, or 

 more deeply between the tendons, ligaments, and fasciae, which 

 on being opened discharge a watery pus, which may be mixed 

 with shreds, or, in more- aggravated cases, with masses of 

 gangrenous tissue. The systemic disturbance is severe ; rigors 

 are frequent; pain is acutely felt; the pulse becomes small, 

 quick, and feeble ; the respirations hurried ; the bowels generally
