300 The Management and Diseases of the 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 tothe 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 septikeemia. 
“ Post-mortem examination of these cases showed that,
