11 ABIES IN THE DOG— SYMPTOMS. 
the difficulty of recognizing the disease in its earliest stage. A 
child in 1813 was bitten by a dog. No one suspected any thing 
about the animal, for the child had taken away its food. Eight 
days afterwards symptoms of hydrophobia appeared in the dog. 
The disease was from the first sufficiently developed in him : the 
salivary fluid was so far vitiated and empoisoned, that he could 
and did communicate the disease, for the child died a little while 
after the dog. 
A boy in Germany was bitten by a dog. Ten days after- 
wards that dog became rabid, and died. No one dreamed of 
danger with regard to the boy, but in process of time he sickened 
and died plainly hydrophobous. 
The case of Mrs. Duff goes to the establishment of the same 
point. Many a day passed before there was any appearance of 
illness about the animal by which she had been bitten. 
After all, however, this is nothing more than is the case in the 
human being. When the circumstances are carefully inquired 
into, the patient has sometimes been oppressed, and languid, 
and feverish, and full of fearful apprehensions, for many a day, 
or more than a week. The empoisonment had then ceased to 
be a local affair ; the constitution was affected ; the virus had 
entered into the circulation, or its impression had been made on 
the constitution generally. 
This is a most serious consideration. Fortunately the dispo- 
sition to bite rarely develops itself until the full establishment of 
the disease ; otherwise, with all their sagacity, affection, and 
fidelity, it would become our bounden duty to extirpate the 
whole race of dogs. 
On October 21st, 1813, a dog was brought to me for exami- 
nation. He had vomited a very considerable quantity of coagu- 
lated blood. I happened to be particularly busy at the time, 
and observed nothing peculiar in his countenance or manner, but 
ordered some astringent sedative medicine to be given to him, 
saying that I would examine him again in the afternoon. In 
the afternoon he was brought to me. The vomiting had quite 
ceased. His mouth seemed to be swelled ; and on examining 
him I found that some of his incisor teeth, both in the upper 
and lower jaw, had been torn out. This somewhat alarmed me, 
and, on inquiring of the servant, I was told that he imagined 
that they had had thieves about the house on the preceding 
night, for the dog had torn away the side of his kennel in 
attempting to escape. I scolded the man well for not having 
told me this ; and then, talking of various things in order to pro- 
long the time that I might closely watch my patient, I saw, or 
thought I saw, but in an exceedingly slight degree, the tracing
