No opportunity of 'post-mortem' examination was lost. In some cases I have found spicula projecting from the inner plate of the skull, and pressing upon or even penetrating the dura mater. I know not why the dog should be more subject to these irregularities of cranial surface than any of our other patients; but decidedly he is so, and where they have pressed upon the brain, there has been injection of the membranes, and sometimes effusion between them. In some cases I have found effusion without this external pressure, and, in some cases, but comparatively few, there has not been any perceptible lesion. Hydatids have been found in the different passages leading to the cranium, but they have not penetrated. I used to recommend that the dog should be destroyed; but I met with two or three favourable cases, and, after that, I determined to try every measure that could possibly be serviceable. I bled, and physicked, and inserted setons, and tried to prevent the utter exhaustion of the animal. When he was unable longer to perform his circumvolutions, and found that he was foiled, he laid himself down, and by degrees resumed his former habits. He was sadly impatient and noisy; but in a few cases he was cured. [We have seen but two or three cases of this disease in dogs, are led to believe that it is quite uncommon with our domestic animals. One case in a valuable setter came on suddenly, and without any apparent cause (except perhaps over-feeding), and terminated fatally in the course of a few days.--L.] EPILEPSY in the dog assumes a most fatal character. It is an accompaniment, or a consequence, of almost every other disease. When the puppy is undergoing the process of dentition, the irritation produced by the pressure of the tooth, as it penetrates the gum, leads on to epilepsy. When he is going through the stages of distemper, with a very little bad treatment, or in spite of the best, fits occur. The degree of intestinal irritation which is caused by worms, is marked by an attack of epilepsy. If the usual exercise be neglected for a few days, and the dog is taken out, and suffered to range as he likes, the accumulation of excitability is expended in a fit. The dog is, without doubt, the most intellectual animal. He is the companion and the friend of man: he exhibits, and is debased by some of his vices; but, to a greater degree than many will allow, he exhibits all the intelligence and the virtues of the biped. In proportion to his bulk, the weight of his brain far exceeds that of any other quadruped--the very smallest animals alone being excepted, in whom there must be a certain accumulation of medullary matter in order to give origin to the nerves of every system, as numerous in the minutest as in him of greatest bulk.
