RABIES CANINA, OR HYDROPHOBIA. 455 



the conjunctiva, dilatation of the pupil, salivation, and 

 slight increase in the nasal secretion. Dogs which are 

 seized with rabies, after having been bitten, manifest irrita- 

 tion in the region of the bite. 



The third stage of rabies is indicated by the animal 

 growing careless regarding the person and things amongst 

 which he has lived. He takes to rove about, to howl 

 piteously, and to bite whenever he can get a chance. The 

 disposition to bite is increased at intervals, and there are 

 paroxysms of apparently great suffering. Any object 

 approached to the animal in this stage is bitten, and it is 

 strange to see how steadily the eyes are kept on any thing 

 moved within sight of a rabid dog. The dread of liquids, 

 or hydrophobia, formerly declared as a symptom of canine 

 rabies, does not exist, though there is difficulty in deglutition, 

 whether of fluids or solids. Every kind of filth is however 

 seized, and in part swallowed. The bark is very peculiar 

 at this stage, and consists rather in a peculiar howl. There 

 is redness and dryness of the visible mucous membranes 

 and intolerance to light, shown by the eyes being kept 

 partially closed. 



The animal is then seen to writhe, to suffer from paralysis, 

 its tail dropping between its hind legs, and the pulse is 

 slow and irregular, breathing laboured, and convulsions 

 occur. These fits are first partial and then complete, 

 killing the animal about the fifth or sixth day from the 

 first appearance of symptoms. 



The form of dumb rabies is more rapid, and is charac- 

 terised by paralysis of the lower jaw, discharge of saliva, 

 swelling of the throat, catarrhal symptoms, very rapid 

 emaciation, and early death. 



Post-Mortem Appearances. There are no specific lesions 

 in the bodies of animals that have died of rabies. The
