VARIETIES, SYMPTOMS, AND COURSE OF THE DISEASE. 95 



follows SO closely in tlie wake of tlicse as does tlie development 

 of additional abscesses and purulent infiltrations characteristic 

 of tlie ordinary irregular forms of the fever. 



Usually one or more abscesses have either naturally or by 

 assistance discharged their contents, and for a few days the 

 animal seems convalescent, when suddenly the febrile symptoms 

 start into greater prominence than at first, and are characterized 

 by regular and recurring paroxysms, accompanied with partial 

 and local sweatings, irregular action of the heart, and accelerated 

 respiration. 



In some cases the temperature has continued steadily high ; 

 more frequently the elevation is concomitant Avith the occur- 

 rence of the paroxysmal attacks ; while between these periods 

 of exacerbations it may be little, if at all, above normal standard. 



Most of the cases exhibiting these symptoms of hectic are 

 observed in animals unfavourably circumstanced either as to 

 original constitutional stamina — that is, that they, previously to 

 the attack of strangles, were not in a state of robust or vigorous 

 health — or that at this particular time they are operated upon 

 by depressing influences, hygienically and dietetically. They 

 may be subjected to the pernicious influence of decomposing 

 organic matter through the medium of the air or drinking- 

 water, while the food supplied may be deficient in nutriment 

 for an aheady exhausted system. 



Immediately following those renewed indications of pyrexia, 

 and certainly not previous to their establishment, there may 

 appear on difierent parts of the body — chiefly the hmbs — small, 

 nodulated tumours, apparently situated in the subcutaneous 

 connective tissue, placed along the course of the vessels on the 

 inner surface of the limb, not unlike at this stage the first 

 appearance of farcy-buds. These shortly soften, and discharge 

 a little piis. More rarely the structures in the vicinity of the 

 joints are specially invaded by similar small abscesses, the 

 destructive effects of which may extend to and impair the 

 integrity of the articulation with which they are connected. 



The more fatal cases, however, are those where these multiple 

 abscesses, developing from several centres of local inflammation, 

 are situated in the more important internal organs — the lungs, 

 the liver, or the heart. When these particular viscera are 

 invaded, there are, in addition to the ordinary tram of symptoms,
