128 PASTEUR AND HYDROPHOBIA III 



In some instances the rabid dog vomits a chocolate or blood- 

 coloured fluid. 



The voice is always changed in tone, and the animal howls or 

 barks in quite a different fashion to what it did in health. The 

 sound is husky and jerking. In "dumb madness" this very 

 important symptom is absent. 



The sensibility of the rabid dog is greatly blunted when it is 

 struck, burned, or wounded ; it emits no cry of pain or sign 

 as when it suffers or is afraid in health. It will even sometimes 

 wound itself severely with its teeth, and without attempting to 

 hurt any person it knows. 



The mad dog is always very much enraged at the sight of an 

 animal of its own species. Even when the malady might be 

 considered as yet in a latent condition, as soon as it sees another 

 dog it shows this strange antipathy and appears desirous of 

 attacking it. This is a most important indication. 



It often flees from home when the ferocious instincts 

 commence to gain an ascendency, and after one, or two, or three 

 days' wanderings, during which it has tried to gratify its mad 

 fancies on all the living creatures it has encountered, it often 

 returns to its master to die. At other times it escapes in the 

 night, and after doing as much damage as its violence prompts it 

 to, it will return again towards morning. The distances a mad 

 dog will travel, even in a short period, are sometimes very 

 great. 



The furious period of rabies is characterised by an expression 

 of ferocity in the animal's physiognomy, and by the desire to 

 bite whenever an opportunity offers. It always prefers to attack 

 another dog, though other animals are also victims. 



The paroxysms of fury are succeeded by periods of com- 

 parative calm, during which the appearance of the creature is 

 liable to mislead the uninitiated as to the nature of the malady. 



The mad dog usually attacks other creatures rather than 

 man when at liberty. When exhausted by the paroxysms and 

 contentions it has experienced, it runs in an unsteady manner, 

 its tail pendent and head inclined towards the ground, its eyes 

 wandering and frequently squinting, and its mouth open, with 

 the bluish-coloured tongue, soiled with dust, protruding. 



In this condition it has no longer the violent aggressive
