308 A TREATISE ON HORSE-BREEDING. 



saliva from the mouth, accelerated breathing and pulse, cos- 

 tiveness, scanty, high-colored urine, and increased thirst. 

 Now the characteristic swellings appear in front of the 

 throat and between the two branches of the lower jaw. This 

 is a uniformly rounded swelling, hot and tender, firm and re- 

 sistant in the center, but softer, more doughy and pitting on 

 pressure on the surface and around the margins. After two 

 or three days, in the regular cases, the center of the swell- 

 ing softens and fluctuates from contained pus, and a few days 

 later still it bursts, discharging an abundant white, creamy 

 matter, and speedily heals up, this being accompanied by a 

 restoration to vigorous health. 



Sometimes the swelling is situated in the throat and may 

 press inward on the pharynx, preventing swallowing and 

 causing a rejection of water and food by.the nose. In other 

 cases it presses on the larynx, shutting off the air from the 

 lungs and causing the most difficult, stertorous breathing, 

 or even proving fatal by suffocation. At other times the 

 swelling beneath the lower jaw is replaced, or supplemented, 

 by similar swellings in distant parts of the body, but mainly 

 in the groups of the lymphatic glands, in the neck, shoulder, 

 groin, chest, abdomen, or elsewhere. In these cases the 

 danger is always greatly enhanced, but it will be proportion- 

 ate to the vitality of the organs in which the inflammation 

 and suppuration supervenes. In some instances the swelling 

 first appears in its natural situation under the jaw, but fails 

 to come to a head, remaining hard and indolent for an 

 indefinite length of time. In all such cases the strength is 

 much run down and there is a great tendency to the forma- 

 tion of matter in important internal organs, and especially 

 in the brain, with fatal results. In such cases, too, there is 

 a great tendency to enormous dropsical and bloody effusions 

 in the head and limbs as the result of debility and a very 

 depraved condition of the blood. 



Suggestion has already been made of the great importance 

 of guarding against exposure to contagion, to change of 

 locality, or to any of the exciting causes of the disease, when 

 that shows any tendency to assume an irregular or fatal 

 form in a district. Disinfectants even may be used in the
