On the 'post-mortem' examination, a remarkable thickness of the meninges was found on almost the whole of the left lobe of the brain. The dura mater, the two leaves of the arachnoid membrane, and the pia mater did not constitute more than one membrane of the usual thickness, and presented a somewhat yellow colouring. The cerebral substance of the left lobe appeared to be a little firmer than that of the right lobe. The fissures of the cerebral devolutions were much less deep than those of the other side The red vessels which ran in the fissures were of smaller size, and in some places could scarcely be discovered. [Confinement, over-feeding, blows on the head or spine, drying up of old ulcers, repelling of cutaneous affections, or, in fact, anything that is liable to derange the general health of the animal, will produce epileptic fits. We formerly had a beagle hound of very active temperament, which we were necessarily obliged to keep much confined while in the city; and to restrain her from running too wildly when taken into the streets, we were in the habit of coupling her with a greyhound of much milder disposition. Not being willing to submit lamely to this unpleasant check upon her liberty, she was ever making fruitless attempts to escape, either by thrusting herself forwards, or obstinately pulling backwards. These efforts resulted on several occasions in fits, produced by congestion of the brain, owing to the pressure of the collar on the neck, thereby interrupting the circulation, and inducing an influx of blood to those parts. We were ultimately obliged to abandon this method of restraint, which nearly proved fatal to our much-admired beagle: she being suddenly seized with one of these fits on a hot summer's day in one of our principal thoroughfares, the crowd of ignorant bystanders concluded it to be a case of rabies, and nothing but my taking her up in my arms, and carrying her from the scene of action, saved her from falling a victim to their ignorance. If the disease appears dependent upon plethora the result of confinement and gross living, the animal must be reduced by bleeding and purging, low diet, and exercise. If, however, the malady proceeds from weakness, as is sometimes the case in bitches while suckling a large litter, it will be necessary to relieve her of some of the pups, and supply her with the most nutritious diet, as also administer tonic balls; the following will answer. [Symbol: Rx]: Extract of Gentian, Quassia, ââ (each) grs. V, made into two pills, and one or two given morning and evening; or, [Symbol: Rx]: Powdered Columbo. Carbonate of Iron, ââ, grs. V, made into two pills, and one given morning and evening, or more frequently if desirable. A seton placed in the poll will often prevent these attacks, particularly when depending upon slight cerebral irritation, accompanying distemper and mange. Blisters and frictions to the spine are also serviceable.--L.] CHOREA.
