Symptoms. 375 



At the onset of the disease the heart's action is only 

 slightly accelerated; with the advance of the suppurating 

 process however the number of heart beats may double, but 

 the pulse remains even then full and tense. 



The body temperature reaches a -high degree even on the 

 first day (40°-41°). On the following days it drops slightly, 

 but on the appearance of suppuration a new rise is observed, 

 and then the fever remains at a comparatively uniform height, 

 until the termination of the suppurating process, or until the 

 bursting of the abscesses. From this stage on the temperature 

 diminishes rapidly, and becomes normal after 1 to 2 days. 



The nutrition is disturbed in all cases, not only on account 

 of the difficult mastication caused by the swelling of the sub- 

 maxillary tissue, but also because of the difficult deglutition 

 brought on by the pharyngitis. The appetite is diminished from 

 the onset of the disease, and the patients take, at best, only 

 small quantities of hay or green feed. 



Defecation is at first retarded, and later an intestinal 

 catarrh sets in not infrequently with the well-known symptoms. 



The urine is passed in diminished amount, its specific 

 gravity is increased, and in the later stages it often contains 

 considerable quantities of albumen. With the ripening of the 

 abscesses the quantity of indican is considerably increased, 

 but drops to normal after the evacuation of the pus ; during con- 

 valescence poljiiria lasting for several days is occasionally ob- 

 served. 



During the beginning or the termination of the disease, 

 the skin shows not infrequently an extensive urticaria, lasting 

 only for a short time, or small vesicles may develop rapidly, 

 which are filled with clear serous fluid. Thin scabs form later 

 at these places, and finally fine white scars remain (according 

 to Woronzow such a skin eruption may precede the character- 

 istic symptoms of strangles). Places of predilection for the 

 eruptions are the cheeks, the parts around the nose and mouth, 

 the neck, the sides of the chest, and the flexor sides of the 

 joints. 



Atypical Forms. In every outbreak there occur cases in 

 which the manifestations deviate considerably from the de- 

 scribed symptoms, and accordingly the course of the disease 

 appears varied. 



In this category belong undoubtedly those catarrhal affec- 

 tions of the upper air passages and the pharynx, which are 

 observed during the disease in a smaller or greater number 

 of animals of the same stable, without the development of the 

 characteristic suppurative inflammation of the lymph glands, 

 or without their having any participation in the disease process. 

 These catarrhs also develop apparently as, a result of the 

 specific streptococcus infection, but inasmuch as the bacteria 

 do not penetrate to the lymph glands, these remain intact or 

 show only an insignificant swelling. The catarrh of the affected
