RABIES IN THE SHEEP—SYMPTOMS.

gland is the principal sufferer, and becomes speedily ulcerated. 
The lininof membrane of the three first stomachs is far from beino- 
generally affected; but the mucous membrane of the fourth 
stomach presents numerous little spherical prominences, caused 
by the presence of some serous fluid in the sub-mucous cellular 
tissue. This is likewise seen in some of the intestines, particu¬ 
larly at the caecum. These prominences are, in most cases, about 
the size of lentils. The internal walls and cavities of the heart 
are of a deep red colour, but the substance of the heart is pale. 
There is usually a slight injection of the membranes of the brain, 
but no affection of its substance. The spinal chord is very 
generally affected, and through the greater part of its extent : it 
has a reddish hue, and is considerably softened, particularly at 
the lumbar region. 
I feel that this account is exceedingly unsatisfactory, and lam 
sorry for it; but I must speak of things as I find them. The 
only indications on which reliance can be placed here are the 
inflammation of the membrane and glands of the mouth, not 
always seen; that of the pharynx, often very obscure ; and the 
peculiar engorgement of the lining membrane of the fourth 
stomach, which is seldom absent. There is no portion of veteri¬ 
nary pathology so neglected as the post-mortem lesions of rabies 
in neat cattle. 
In Sheep .—I am enabled to give a somewhat more satisfactory 
account of these lesions in the rabid sheep, from one dissection 
which I was enabled to make, and from the notices of Messrs. 
Yvart and Yatel, at Alfort, and my friend Mr. Baker, at 
Sudbury. 
The tongue almost uniformly presents a peculiar appearance. 
The epidermis is dry and somewhat irritated ; and, surrounding 
the edges of the tongue, and almost in the form of a riband, are a 
succession of fungous ulcers, varying from the size of a pin’s 
head to an irregular surface of nearly half an inch in diameter : 
some of these ulcers penetrate considerably beneath the cutis. 
These may, however, be in a great measure mechanical, and 
caused by the unnatural and hard substances which the rabid 
sheep will so frequently and obstinately seize and endeavour to 
masticate. The back part of the mouth generally participates in 
the inflammation, and usually the inflammatory blush extends to 
the pharynx and larynx, and superior part of the trachea. In 
many cases, however, perhaps the majority of them, there is very 
slight change of colour on any of these membranes. It is not al¬ 
ways that the lungs present any morbid lesions ; but in the sheep 
examined by Mr. Baker they were a ‘‘ little flushed,” and they 
had a few almost black spots, about the size of a hazel nut, on
