90 STRANGLES. 



in the animal ''tissues with which it may come in contact, or 

 Hving particulate organisms, either the carriers of the actual 

 and potential contagium, or the contagium itself, but at all 

 events capable of inducing in the previously healthy a similar 

 train of phenomena to that Avhich we observe in the diseased 

 whence these organisms or potentialities come. 



Varieties, Symptoms, and Course of the Disease. 



In many instances the nature, development, and course of 

 strangles are very complicated. Instead of a few days of simple 

 irritative fever, steadily maintained until the maturation of 

 the submaxillary swelling, with regular but steady decline of 

 symptoms, the discharge of the pus and the progress of the local 

 healing process, we may encounter true ' hectic,' the fever of 

 suppuration passing on to or terminating in the appearance of 

 variously situated abscesses, more rarely septiccainia. 



In these cases, instead of simple and continued fever where 

 the pyrexial symptoms are steady, with slight exacerbations 

 from outset until the termination, or rather until defer- 

 vescence, we have frequent remissions and accessions usually 

 at periodic intervals, the paroxysms accompanied by local 

 or patchy sweatings, and attended with emaciation and pro- 

 stration. 



The pyiemic state, consisting of this hectic fever, Avith 

 accompanying disseminated abscesses distributed over various 

 parts ot the body, but having a partiality for location in con- 

 nection with lymphatic glands and vessels, generally succeeds 

 the subsidence of the original or primary fever ; and occasionally 

 also the eruption of a primary abscess and discharge of pus. It is 

 characteristic of particular outbreaks of this fever of strangles, 

 is a speciality of certain appearances of it as an epizootic, and 

 sometimes seems much influenced as to the strength of its 

 development by the character of the influences which sur- 

 round the animals afl'ected. 



With a view to give due consideration to these facts, 

 observers, in speaking of this fever, have endeavoured to 

 arrange it in forms and varieties. These with advantage may 

 justly and conveniently bo all gathered or grouped under two 

 divisions : 1. Simple, benign, or regular strangles ; 2. Compli- 

 cated, malignant, or irregular strangles. The symptoms of
