symptoms spring from this specific laryngitis and bronchitis, by 

 which these parts are tumefied even to pai'alysis, 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, tv\^itchings 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 cii'cle ; 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
