symptoms spring from this specific laryngitis and bronchitis, by 
which these parts are tumefied even to paralysis, yet are totally 
free from any of the human spasmodic rigors. It is, however, 
far otherwise with the external muscular tissues : the cutaneous 
muscles become often first affected, twitchings pass over the 
face, and afterwards the spasmodic and paralytic affection fre¬ 
quently extends also to all the organs of locomotion : in others, 
it is principally confined to the loins and hinder extremities. 
When the morbid affection acts very strongly on the bowels, it 
occasions the hinder parts to be drawn forward by a species of 
tetanic spasm toward the fore parts, so as to bend the body of 
the poor sufferer into a circle ; sometimes it fixes the animal on 
his rump, almost upright. 
“ A symptom common to dumb madness, and not altogether 
uncommon in the more raging kind also, is a disposition to carry 
straw, litter, or other matters, about in the mouth, which the 
dog seems to make a bed of, frequently altering it, pulling it to 
pieces, and again remaking it. It is also very common to ob¬ 
serve dogs scratch their litter under them with their fore feet, 
not as when making their beds, but evidently to press the straw 
or litter to the belly. This peculiarity appears to arise from 
some particular sympathy with the intestines, which, in these 
cases, are always after death observed to be very highly inflamed. 
There is also present a disposition to pick up and to swallow, 
when not prevented by the affection of the throat, indigestible 
and unnatural substances, selected from whatever is around 
them, and which the costiveness usually present tends to retain 
within the body. It appears to be this impulse, likewise, that 
leads rabid dogs to gnaw boards, or whatever is within their 
reach ; and this aptitude may be considered as common to every 
variety of the complaint, except, as already observed, where the 
tumefaction and paralysis of the throat are so extreme as alto¬ 
gether to prevent it. 
“ The irritability attendant on dumb madness is even subject to 
more variation than that called the raging. It is sometimes con¬ 
siderable, and exhibits all the treacherous and mischievous dis¬ 
position that marks the other ; but when the dumb character
