300 The Management and Diseases of tJu Dog. 



occurs amongst animals, which is rather puzzling to those 

 engaged in their management, poison administered 

 maliciously, or obtained accidentally, was credited with the 

 mortality. An analysis, however, of the viscera of two 

 animals negatived this idea. The average duration of the 

 disease in those fatal cases was a little over two days ; 

 many died earlier, and none survived beyond the fourth 

 day. 



" With the exception of the glands of the throat and 

 cervical region, the structural alterations observable in all 

 cases may be said to have been confined to the fauces and 

 the air passages anterior to the glottis. The urine, in all ' 

 the instances where this secretion was examined, was 

 opaque, increased in density, and charged with albu- 

 men. 



"In some cases, from the outset, the fever was high, the 

 local inflammatory action markedly acute, the mucous 

 membrane over the fauces, tonsils and palate became of a 

 dark-red colour, tense, smooth, and glistening in appear- 

 ance, apparently from distension from infiltration of the ■ 

 submucous tissue. In these also the whole gland-structures 

 of the mouth and throat were more or less swollen and 

 tender, with deglutition from the first extremely difficult or 

 altogether impossible. The earliest stages were marked 

 by exaltation of temperature, accelerated pulse and re- 

 spirations, together with slight restlessness, if not actually 

 giving evidence of pain ; very shortly, however, these signs 

 of increased functional activity disappeared, there was 

 marked depression, listlessness, and want of muscular 

 energy ; emesis and diarrhoea might also be present. 



" The majority of the cases were of this type, and they 

 ■were also those which succumbed the quickest, death in 

 them seeming to result as much from the extension of the 

 local diseased action into the larynx as from the virulence 

 of the septikffimia. 



" Post-mortem examination of these cases showed that,
