CASE OF RABIES IN THE DOG. 
shifting his posture and scraping his bed together almost every 
instant. No howling, nor the least disposition to bite. 
Mr. Mayo had expressed a wish to experiment on a rabid dog. 
He favoured me with a call about 9 o’clock. Seven ounces of 
blood were detracted from the jugular; and an attempt was made 
to inject an equal quantity of warm water. The experiment did 
not perfectly succeed. Five or six ounces more of blood were 
lost, and eight or ten ounces of water injected. During the 
process of injection the animal heaved convulsively, and vomited 
twice. 
Nothing more was done for a quarter of an hour. The la¬ 
borious breathing and choaking inspiration evidently increasing, 
the anterior portion of the second ring of the trachea was excised. 
This afforded not the slightest relief, but, on the contrary, the 
hoarse, grating, choaking inspiration was decidedly aggravated. 
The poor fellow was again liberated. He was very weak, con¬ 
tinually shifted his posture, but was afraid to lie down. At 
12 o’clock I saw him again. He was sitting leaning against the 
wall, and scarcely looked up, but the heaving at the flanks and 
the hoarse grating sound were the same. 
Nov. 27th, 6 A. M. He was found dead : he had slipped a little 
from his leaning posture, and must have died without a struggle. 
At 12 the post-mortem examination took place. Slight vas¬ 
cularity of the pia mater—none of the cerebrum or cerebellum. 
No fluid in the ventricles, or vascularity of the plexus choroides. 
The medulla oblongata, on being cut into, shewed slight pinkiness 
of substance. Some fluid between the dura mater and the spinal 
cord, and considerable injection of the sheath of the spinal marrow 
through its whole extent. The tongue was discoloured at its ex¬ 
tremity—no vesicle or swelling of the froenum. No inflammation 
of the pharynx, the larynx, the trachea, the bronchial passages, 
or the substance of the lungs. The bronchiae, however, were 
filled with bloody spume ; and there was slight injection of the 
epiglottis, with turgescence of the small vessels in the angle 
behind. The muscular substance of the heart was dark-coloured, 
but no ecchymosis. No inflammation of the oesophagus. Much 
bile had been thrown into the stomach, and had stained the 
whole of that viscus. Most of the rugae were inflamed, but not 
violently: no ecchymosis. Not the smallest portion of indigesta 
in the stomach. Much bile in the duodenum, and slight peri¬ 
toneal inflammation through the whole of the intestines. 
This was a singular case, in some respects deceptive, yet clearly 
marked. The disease was evidently cut short by the two important 
experiments, the result of which will furnish matter for observation 
hereafter.
