ANIMAL PATHOLOGY. 
By Mr, Youatt. 
LECTURE XIX. 
The Cause of Rabies—No Reasoning from Analogy admitted — 
The Cause in the Human Being—The Quadruped—Is want 
of Ventilation a Cause ?—or Heat ?—Atmospheric Influence ?— 
Thirst^—The Origin of the present too prevalent Opinion — 
The Origin of Rabies — I'he Ease with which the Inoculation 
ma^ be unknowingly effected—The immediate Consequences of it 
—The Virus resides in the Saliva—Can all Animals communi¬ 
cate the Disease ?—It can be communicated by the Carnivorous 
and Herbivorous—Can it by the Horse, Sheepy or Cattle —The 
Importance of settling the Question — Caution, 
WHAT is the cause of this fearful disease that has so long 
occupied our attention? I answer at once— the saliva of a rabid 
animal received into a woundj or on an abraded or mucous sur¬ 
face, Do I admit no other cause? I will admit any thing, 
every thing that is based on facts; but I will listen to no ana¬ 
logical reasoning—to no theoretical speculation. I must have 
plain, broad, palpable facts. I will have no reasoning from the 
cause or progress or termination of one disease to that of another; 
for I cannot have been long in practice—I can have paid but 
little attention to my profession, ere I have a thousand proofs 
that every disease is governed by its own laws, and by those 
alone. To those, discovered and proved by my own experience, 
or that of others, will I appeal, and to nought beside. 
No Reasoning from Analogy admitted, —I glance at the list 
of animal poisons. Syphilis is communicable only by the con¬ 
tact of the virus with an abraded or mucous surface. What 
should I say to the young man who, labouring under this dis¬ 
ease, stoutly maintained that he was not paying the price of his 
own folly. Variola, distemper, malignant fevers, are communi-
