paroxysms. Exhaustion, acceleration of respiration, prostra- 

 tion, local dropsies, marked wasting of tissue, and occasion- 

 ally irregular cardiac action follow. 



Difficulty of respiration and cough usually occur, if the 

 abscess be in connection with the mediastinum, and death 

 may ensue from pus finding its way into the bronchi, or 

 owing to the neighbouring organs becoming involved in the 

 inflammation. If the mesenteric glands be affected, peri- 

 tonitis may ensue and prove fatal. 



Sequelae of Strangles. — Eoaring, or whistling, is some- 

 times left as a sequel of strangles. The most important 

 sequelae, however, are pysemia and septicaemia, the former 

 being accompanied by the formation of abscesses. The onset 

 of pysemia is accompanied by sudden increase in the febrile 

 manifestations by regularly recurring paroxysms, irregular 

 action of the heart, and accelerated respiration. Shortly, 

 multiple abscesses form in various parts, especially in the 

 limbs. The structures in connection with the joints may be 

 invaded by these small abscesses. When the lung or heart 

 or liver is invaded, there is but little hope of recovery, and 

 pneumonic, cardiac, or enteric symptoms are developed. 



Bacteria have been demonstrated in pyemic lesions, and 

 it is probable that when pysemia results in cases of strangles, 

 it is traceable to the fact that the animal has been 

 under bad hygienic conditions during the primary 

 malady. 



Treatment of Strangles. — The animal should be placed 

 under good sanitary conditions. In mild cases, such remedies 

 as magnesium sulphate, sodium sulphate, potassium nitrate 

 and bicarbonate will suffice. ^ If laryngitis and tracheitis 

 be present, camphor, ipecacuanha, and potassium nitrate 

 may be administered. Inhalations of carbolised steam are 

 of great value. Counter-irritants may be applied to the 

 throat : for this purpose we may use ammoniacal liniments
