RABIES. 211 
bucketful of cold water poured on his head, or even were he left undisturbed, in 
the course of an hour he would likely be playing about, showing no sign what- 
soever of his ill turn. 
Among the causes of coryza or nasal catarrh is a small tenia-like parasite. 
This excites a severe inflammation of the upper nasal cavities and sinuses of the 
forehead, which may extend to the brain and produce terrifying symptoms, as 
great excitement and restlessness, snapping and biting, also paralysis of the 
lower jaw, which are certainly identical with some of the most prominent signs 
of rabies. 
Some breeds, as, for instance, sporting-dogs, have nervous systems that are 
adjusted with exceeding nicety. They are what would commonly be termed 
“high strung,” and easily thrown off the balance. With this condition there is 
associated a natural tendency to certain disorders which are likely to be compli- 
cated with brain symptoms, as delirium and convulsions. Again, there are 
affections that give rise to symptoms so closely resembling those exhibited by a 
rabid dog that one could not distinguish the positive ailment with anything like 
certainty. As an illustration, the effects of the parasite giant strongle are cited. 
This occasionally finds its way into the kidneys, not only of men, but of dogs, 
and in the latter causes symptoms which are very like those of rabies. There is 
a disposition to bite, the sufferer avoids the light, his mouth is red, and from 
it there falls a thick, ropy, mucous discharge; while his voice is hoarse, gait 
vacillating, and expression changed, although indicating suffering rather than 
ferocity. 
A dog presenting those symptoms is sure to be killed as rabid, notwithstand- 
ing he is suffering from inflammation of the kidneys induced by the parasite 
named. 
The symptoms of dumb rabies are rather more distinctive than those of the 
maniacal form; and yet much the same may be induced by an irritant poison, 
which, taken into the mouth, causes the tongue to swell and protrude. A dog so 
unfortunate would for a time have mucus and saliva in abundance, and this 
discharge would be thick and ropy. His mouth would be very red and con- 
stantly open, and one could scarcely tell whether the inability to shut his jaws 
was due to paralysis—a characteristic symptom of dumb rabies —or to the 
swelling of the tongue. 
In such condition a dog could not swallow, or only with exceeding difficulty, 
and thus would exhibit another peculiarity so prominent in dogs with dumb 
rabies; namely, he would plunge his muzzle into water up to the very eyes, 
in order to get a few drops into the back part of his mouth, to cool his burning 
throat. 
Many other illustrations might be given of comparatively innocent derange- 
ments and diseases which are manifested by symptoms resembling those of 
rabies, as severe pain, especially in an ear or a tooth, excessive and terrorizing
