change in the character of the wound from which the dis- 

 ease resulted. Formerly red and covered with exuberant 

 granulations that are discharging an abundance of pus of 

 usual character, it is seen to modify as the disease begins. 

 The granulations become sunken, tarnished, livid, gray, lead- 

 colored, and flabby, and discharge a bloody pus, tainted 

 with a stringy serum of a reddish-yellow color. 



After a variable time the general symptoms amend and 

 the patient seems to recuperate its health. The temperature 

 falls and the principal functions regain their normal condi-

 than the first, accompanied with profuse perspiration, staring

 more depressed. They correspond to successive infections, 

 which appear to be formed in large doses. Symptoms which 

 vary according to the organ in which the abscess is located 

 then supervene. If located in an articulation there will be an 

 inability to support weight and very acute pain over the joint, 

 and the purulent collection will develop rapidly and will al- 

 ways contain a large quantity of pus. If 'the abscess is in the 

 lungs, attention is drawn to the respiratory symptoms. 

 There will be an icterus if the liver is the seat, and puru- 

 lent nephritis if located in the kidneys. 



The urine is albuminous and contains blood, pus cells 

 and micro-organisms. The patient becomes weaker and

 very dififerent. There appears suddenly a formidable chill, 

 staring coat, tremor over the entire body, sunken eyes, dry 

 muzzle and pale mucous membranes. The skin, horns, ears, 

 forehead, and extremities are coldi, and the patient pays no
