RABIES COMMUNICATED TO A HORSE. 
parts of the body. There was no apparent wildness—no attempt 
to bite or kick—and very little foam was discharged from the mouth. 
The animal lay in this state from the evening of the 20th to the 
23d of June, quite motionless, neither eating nor drinking, and the 
jaws clenched so that no medicine could be administered. 
On the morning of the 23d she became covered with perspira¬ 
tion, which had a strong disagreeable odour, as was also the case 
with her breath. Towards noon she died without a struggle. 
On making a post-mortem examination, the following appear¬ 
ances were observable :—An indescribable stench proceeded from 
the bod}^; the muscles were pale, very flaccid, and of an ashen-grey 
hue, and smelled like carrion. All the intestines were inflamed 
and flaccid. There was food in the stomach, although the animal 
had not eaten for four days. The liver was bloodless, flaccid, 
easily crushed, and of a grey colour; the spleen empty and flabby, 
but of its natural hue, and the kidneys slightly inflamed. There 
was a slight extravasation of serum in the chest; the left lung 
adhered to the lining membrane of the thorax. The substance of 
the lungs was soft, gangrenous, and stinking. The heart contained 
no blood. There was a small portion of serum in the pericardium. 
The membranes of the brain were inflamed, and the veins were 
filled with blood. 
The symptoms and progress of these cases plainly shew that 
they are that species of rabies known in the dog by the term of 
dumb madnessand the early palsy which comes on causes 
the animal to be harmless, although for the whole continuance of 
the disease the animal may still retain a desire to do mischief. If 
we compare this case with the preceding one, we shall find several 
interesting variations. The girl retained her senses until the last 
moment, while the horse seemed perfectly unconscious. The for¬ 
mer had a horror of water, air, and light, and an increased secre¬ 
tion of saliva, none of which symptoms were apparent in the 
latter. Both had a calm pulse (which I also found in a dog that 
had shewn symptoms of rabies for three days)—both had the same 
convulsions of the upper limbs and head, the same anxious look, 
and the same want of appetite; and both died quietly. 
These cases tend to confirm the observations of Hertwig, Prinz, 
Delafond, and Youatt in his interesting communications on this 
subject published in The VETERINARIAN —that the post-mortem 
examination is not always satisfactory. In the foxes, it was re¬ 
marked that the almost sole pathognomonical symptom of rabies in 
the dog, viz. the presence of foreign bodies in the stomach, was often 
wanting; the spleen, also, in several of these cases presented no 
morbid appearance; but whether the inflammation of the throat, the 
salivarv glands, the stomach, and the contents of the latter, are to
