ANIMAL PATHOLOGY". 
moment the dog quitted the sop, and with a furious bark sprung 
against the wall, as if he would seize some imaginary object that 
he fancied was there. “ And have you seen that, sir? What do 
you think now V * was my reply. “ He saw nothing in it ; the 
dog had heard some noise on the other side of the wall, he sup- 
posed.” However, he at length consented to excise the part. 
I procured a poor worthless cur, got him bitten by this dog, and 
carried the disease from dog to dog, to the third victim ; and there 
my experiment ended. 
This kind of delirium is of frequent occurrence in the human 
patient. How appropriate to our present purpose, and how gra- 
phic, how horrible, is the account given by Dr. Bardsley of one 
of his patients ! “ I observed that he frequently fixed his eyes 
with horror and affright on some ideal object, and then, with a 
sudden and violent emotion, buried his head beneath the bed- 
clothes. The next time I saw him repeat this action, I was in- 
duced to inquire into the cause of his terror ; he eagerly asked 
if I had not heard howlings and scratchings. On being answered 
in the negative, he suddenly threw himself on his knees, extend- 
ing his arms in a defensive posture, and, forcibly throwing back 
his head and body. The muscles of the face were agitated by va- 
rious spasmodic contractions ; his eye-balls glared, and seemed 
ready to start from their sockets ; and at that moment, when 
crying out in an agonizing tone, ‘ Do you see that black dog V 
his countenance and attitude exhibited the most dreadful picture 
of complicated horror, distress, and rage, that words can describe 
or imagination paint.” 
I have again and again seen the rabid dog start up after a 
momentary quietude, with unmingled ferocity depicted on his 
countenance, and plunge with a savage howl to the end of his 
chain. At other times he would stop and watch the nails in the 
partition of the stable in which he was confined, and, fancying 
them to move, he would dart at them, and occasionally sadly bruise 
and injure himself from being no longer able to measure the dis- 
tance of the object. This, I repeat, is a symptom that will never 
deceive; for although the human being, under cerebral affections 
of different kinds, is liable to strange wanderings, the delirium 
of the dog, intellectual as he is, is rarely or never observed 
unless under the influence of this disease. We will try our 
friend behind the screen presently. 
One of Mr. Babington’s patients thought that there was a 
cloud of flies about him. “ Why do you not kill those flies?” 
he would cry ; and then he would strike at them with his hand, 
and shrink under the bed-clothes, as if afraid of them.
