The intestines may show congestions, colorless or hsemorrhagic 

 exudate, and suppurations in the agminated or solitary glands, 

 or submucosa. The intestinal, mesenteric and sublumbar lymph 

 glands may be the centres of abscesses of varying sizes. 



Abscesses may also be found in the liver, pancreas, spleen, 

 of variable size and usually as secondary formations. 



The muscles and intermuscular tissue may be the seat of more 

 or less extensive exudation, and abscess, and the bones may be 

 congested and swollen especially in their epiphyses. This may 

 extend to suppuration or necroisis. 



The sj'novial membranes of joints and the tendinous sheaths 

 are not infrequently inflamed cau.sing distension and even suppu- 

 ration. 



Congestions of the skin are sometimes met with developing as 

 multiple papules or hard nodules which advance to the formation 

 of pustules or small abscesses. These often appear especially 

 where the skin is thin and delicate as around the lips, nose and 

 eyes, close to the anus or vulva, in the perineum, sheath or mam- 

 mae, inside the thighs or elbow. They may be of all dimensions 

 from a millet seed upward, and may merge into or become com- 

 plicated by the extensive engorgements of petechial fever. 



Finally lesions of the nerve centres are to be looked for in the 

 protracted or irregular types of the disease. There may be simple 

 congestion, or serous effusion, intraventricular or subarachnoid, 

 or finally abscess in the brain, spinal cord or meninges. 



Forms of Strangles. The types of strangles vary, special forms 

 characterizing given epizootics or seasons, or at other times as 

 individual deviations from the current type. Divi.sion has been 

 made into two groups — mild and malignant, or again into regular 

 and irregular, under each of which come several varieties. Many 

 of these varieties consist simply in a difference in the seat of the 

 principle lesions, which start in lymph glands or tissues at a dis- 

 tance from the nasal mucosa, or they depend on secondary foci of 

 infection supervening on the primary disease in the head. 



Incubation. In inoculated cases this lasts from three to five 

 days, in those due to simple exposure it may appear to extend 

 over eight days. 



General Symptoms. In nearly all cases alike there is a marked 

 constitutional disturbance the temperature often rising at once to
