thronged the yard, continued to enjoy perfect health. Yet 

 the pond from which the latter drank was being continually 

 polluted by a drain which received the whole bulk of the 

 intestinal discharges from the fever patients !* The state- 

 ment of ' H. H.' that the symptoms of distemper in the dog 

 and typhoid fever in man are ' alike,' is true only so far as 

 refers to the febrile state. The specific phenomena of the 

 latter most surely find no counterpart in the symptoma- 

 tology of the former. It is only in the continued type 

 of the fever that any identity can really be said to exist. 

 If we examine the main features of the two affections, we 

 find at once a broad and unmistakable difference in their 

 clinical and pathological equivalents. 



" Typhoid fever is an eruptive disease. Its course and 

 duration are definite, and the lesions resulting from the fever 

 process are localised and specific. In distemper of the dog 

 not one of these essential characters can be applied. The 

 pathological changes of the latter have no specific form or 

 seat. Universal congestion more or less intense, local 

 inflammation, blood extravasations, and serous exudation 

 of varying extent, constitute the principal post-mortem 

 phenomena."t 



MALIGNANT DISTEMPER. 



In 1 88 1 and 1882 I had occasion to investigate the 

 causes and nature of a malignant outbreak of disease in 

 various parts of England. I received many dogs, alive and 

 dead, for examination and advice, the victims of this malady, 

 which proved to be a severe form of distemper associated 

 with diphtheria and rash. The symptoms usually presented 

 were as follows : —
