STRANGLES 139 



and persists indefinitely, at times dropping a degree or 

 two and then suddenly rising again. The submaxillary 

 enlargement goes over into abscess formation; the for- 

 mation of abscess in the sub-lingual, retro-pharyngeal 

 and other lymphatic glands, follows. The parotid glands 

 may next show enlargement, followed by pus formation. 

 As a result of swelling which accompanies the formation 

 of multiple abscesses in the laryngeal region and pharynx, 

 there may follow serious dyspnea, so that tracheotomy 

 may have to be performed. 



In a number of cases the trouble does not stop here. 

 There may follow an inflammation of the lungs, or pleu- 

 risy accompanied by empyema may develop. The facial 

 sinuses may become the seat of a purulent process, be- 

 coming filled with pus. In several cases I have seen 

 abscess formation in various abdominal viscera. Abscess 

 formation occasionally occurs in lymphatic glands in 

 distant parts of the body, and skin lesions are not ex- 

 ceptional. 



The course of the disease in an irregular form is very 

 protracted, sometimes requiring two months' time before 

 all manifestations of the disease have disappeared. Usu- 

 ally the abscess formation goes forward in a successive 

 manner, one forms after another; it is astounding in 

 some cases to witness the progress. In the region of the 

 head and neck I have seen as many as twenty individual 

 abscesses. At the same time it is remarkable how well 

 a colt will pass through, even a most severe case, at times. 

 Permanent sequelee are quite rare. One attack of this 

 disease is generally presumed to make the recovered horse 

 permanently immune. 



Treatment. For the handling of strangles in any form, 

 from the most ordinary attack to the most exaggerated, 

 we have two means that alone can be relied upon. There 

 are others, but the two that I am about to name are the
