MINUTES OF EVIDENCE ON CANINE MADNESS. 19 
How lone does he continue in this rabid state?—From four 
to six days. 
In what state does he die?—He gradually becomes weaker, 
principally in the loins; the weakness increases, and he dies, as 
the other, almost without a struggle. 
Do the symptoms after the death of the dogs which die with 
the ferocious madness differ from those that die of the dumb 
madness ?—There is more inflammation in the back part of the 
mouth; there is oftener indigestible matter in the stomach, 
and more inflammation of the stomach: I know no other dif¬ 
ference. 
They seem merely aggravations of all the symptoms of the 
other ?—Yes. 
Did you ever dissect a dog in the early stages of ferocious 
madness, and was there any difference between the symptoms 
of the one dissected in the early stages of dumb madness ?—In 
a dog destroyed in the early stage there is evident inflammation, 
but not so intense; spots of extravasated blood are in the sto¬ 
mach of a dog left to die, which are seldom seen if he is de¬ 
stroyed in an earlier stage. . „ 
Can you, from your experience, state what produces the dif¬ 
ference between those two species of madness, and whether you 
consider them merely modifications of the same disease, or dis¬ 
tinct disorders?—Modifications of the same disease. I have 
found, on inoculation from a dog which died under melancholy 
or dumb madness, that the ferocious madness and the dumb 
madness have been indiscriminately produced. 
Is it your opinion that hydrophobia can be produced by irri¬ 
tating a dog, or by any peculiar mode of treatment, such as 
bad food, exposure to the sun, or w ant of water ?—No. At the 
Veterinary School at Alfort three dogs were selected as the 
subjects of some very cruel but decisive experiments. It was 
during the heat of summer,- and they were all chained in the 
full blaze of the sun. To one, salted meat alone was given ; to 
the second, water only; and to the third, neither food nor drink: 
they all died, but not one of them exhibited the slightest symp¬ 
tom of rabies. 
Do you suppose this circumstance will-predispose a dog to 
hydrophobia, as that a smaller quantity of virus will produce 
disease in a dog so treated than in another of a more vigor¬ 
ous state of temperament ? — l cannot speak to this from ex¬ 
perience. 
Have you ever given the virus of a dog in a rabid state in the 
shape of food to another dog, so as to be taken into the stomach ? 
-Yes.
