 Sometimes, owing to bi"ain complication, the sufferer 

 engages in a continual walking in one direction, and in 

 the form of a circle, evidently in a state of stupor or 

 partial insensibility, which terminates in complete coma 

 and death. 



The Respiratory or Pulmonary form of Distemper is 

 essentially that of Bro7ich,itis of a low and aggravated 

 character, the post-mortem evidences being those 

 common to the usual disease of that name, but asso- 

 ciated with general specific blood derangement. i^See 

 Bronchitis.) 



In the Biliary or Hepatic form jaundice is conspicuous 

 by the yellow colour pervading the tissues generally. 

 The tinge, more or less intense, is seen to great advan- 

 tage in the mucous membranes of the mouth, tongue, 

 nostrils, eyelids, eyeball, the haw, vulva, and rectum. It 

 is associated with intense depression, a feature which 

 adds considerable difficulty in combating the associated 

 blood poison and its destructive effects. {^Scc Jaundice.) 



Enteric or Intestinal Distemper is principally confined 

 to younger dogs and puppies, which are peculiarly liable 

 in their immature state of physical development to con- 

 tract a state of blood disease, even under the least 

 favourable circumstances. Worms in the intestines, also 

 teething, often prove exceedingly trying to these creatures, 

 and under their continued effects, without due care as to 

 suitable food, exercise according to capacity, comfortable 

 quarters, &c., the causes of blood derangement are not 

 far distant. 



In ordinary Distemper the tendency to a loose state of 

 the bowels is general, thus completing the list of signs 

 which are characteristic of blood diseases. A state of 

 looseness is often present from the first, the faeces being 

 laden with mucus shed by the lining membrane of the 

 bowels. Further action induces congestion of the tissues, 

 which is followed by rupture of the minute vessels ; 

 blood oozes, and being irritant as well as an animal 

 poison, causes stoppage and sloughing, when an ulcer 

 forms, another source of bleeding; thus the faeces
