SYMPTOMS OF RARIES IN THE DOG. 405 
he dog; but may be reduced to two classes, characteristic of 
icute and dumb madness. 
In acute rabies the dog is in constant action, running hither 
md thither, escaping from his master’s house, and, after a while 
eturning. The rabid dog knows his master to the very teraii- 
lation of the disease, and obeys him at the commencement of it. 
le loses his appetite at the beginning of the disease; a depraved 
ippetite succeeds, and he eats wood, straw, hair, and other unu- 
,ual and indigestible substances. He is anxious for water; con- 
itipated. The most constant symptom is a change of voice. It is 
:ither considerably higher or lower than the usual tone, and always 
i little hoarse and disagreeable. The bark approaches to howling. 
The desire to bite manifests itself, sooner or later, in almost every 
abid dog. He imagines that flies are passing before him, and 
naps at them. His general appearance is not much changed at 
he beginning of the disease; but the eyes soon become red and 
njected ; they droop and close from time to time; at length they 
>ecome cloudy and perfectly opaque; the skin of the forehead is 
vrinkled, and death approaches, preceded by palsy of the hinder 
‘Xtremities. 
In dumb (taciturne) madness, from almost the commencement 
>f the disease, the lower jaw hangs down as if it were paralysed; 
md this prevents the dog from eating and drinking, and occasions 
:i continual flow of saliva: the tongue is protruded, and hangs 
lown. The dog cannot bite so easily as under acute madness; 
lor is he so much disposed to bite: he is more tranquil and me- 
ancholy than under acute madness. 
The disease, in neither case, is lengthened beyond ten days. 
ON CASTRATION. 
Extract of a Letter from Mr. Brettargii to Mr. W. Percivall . 
Preston, 10th July, 1829. 
Sir, 
\S I am in the habit of purchasing every work that is published 
>n the veterinaiy art, your series of Elementary Lectures na- 
urally came into my possession; and I feel happy in acknow- 
edging them to contain more practical truths and correct anato- 
nical descriptions than any other work on the subject. Yet it 
,on tains (and what work does not) a few errors. The one which 1 
consider the most glaring is in page Ilf), part&l, wherein you state 
hat, the testicles of the colt at three months old are “ within the 
:avity of the abdomen,” as you “full well know.”
