REPORT ON THE CATTLE PLAQUE.

legs gathered together under the belly. The respiration was, however, 
undisturbed; the vessels of the conjunctiva were uninjected, and the 
muzzle was moist. No tenderness along the course of the spine was 
evinced on the application of pressure. 
At night, with the exception of increased weakness and the 
passing of liquid faecal evacuations, there was no material change in 
the symptoms. 
8th.—The pulse now numbers 65, and has lost its sharp beat; the 
breathing is a little quickened ; the diarrhoea has passed into dysentery; 
the animal’s appearance is very dejected; a discharge flows from the 
nostrils and eyes; the coat is staring; the spasm of the muscles is more 
intense; the extremities and body are cold, and the prostration of the 
vital powers is very considerable. 
9 p.m.—The pulse has risen to 75, and can be felt only with difficulty 
in the arteries; the breathing has become very much quicker during the 
day, and now numbers 24 in the minute ; the dysentery is profuse, and 
tenesmus is likewise present. The other symptoms remain about the 
same as in the morning. 
9th.—The symptoms are all increased in severity, excepting that the 
tremors have nearly disappeared; the abdomen is much pinched in; 
small quantities of blood stain the alvine evacuations, which are like¬ 
wise very foetid; the pulse is remarkably tremulous, and the re¬ 
spiration is short and quick. The animal will, however, take a little 
water to drink. 
10th.—During this day she struggled on against the disease, but 
sunk about midnight, being far too weak to rise for several hours 
before death. 
. Post-mortem , eight hours after death.—No congestion of the super¬ 
ficial vessels, nor change in the colour of the flesh was observed on 
the removal of the skin, nor was there much tendency to decompo¬ 
sition of the body. The blood, however, was fluid, and of a dark colour 
in all the large veins. Ulceration had commenced in several places on 
the dorsum and root of the tongue, especially around the bases of the 
conical papillae. The fauces, velum palati, pharynx and larynx were also 
ulcerated here and there in patches of about the size of a shilling; the 
mucous membrane of the posterior nasal opening was intensely red¬ 
dened, and studded with yellowish-coloured points from effusions of 
lymph into its follicles : the ducts of the tonsils were also filled to 
repletion with lymph. The lining membrane of the windpipe and 
bronchial tubes was but slightly congested, but in many places it was 
covered with layers of effused lymph. The substance of the lungs was 
healthy, as was their serous covering. The heart was rather flaccid: no 
blood was found in its ventricles. 
On opening the abdomen some petechial spots were found on the omen¬ 
tum, but otherwise the serous membrane was free from any vascular
