13th. The dog had lain slightly spasmed for two or three days, when they all at once ceased, and the animal appeared as well as before. Suddenly he was taken with another fit, and again a vast quantity of food was vomited. These spasms remained two days, but on the 21st the fit returned with the same discharge of food. Courses of purgatives were then determined on. A strong dose of sulphate of magnesia was given every third day. After four doses had been given, it was impossible to force any more upon him. The syrup of buckthorn was tried, but the fourth dose of that it was impossible to give. The dog was then sent into the country; no fit occurred, but there were occasional spasms. 23d September.--He was brought back to town, and I saw him. During the last month he had had many fits. His owner at length consented that the actual cautery should be applied to his head. The searing-iron for doctoring was used, and applied red-hot to the centre of the head. It was exceedingly difficult so to confine the dog as to make the application effectual, without destroying the skin. Under the influence of the sudden violent pain, he wandered about for more than two hours, and then the spasms returned with greater force than usual. He refused all food. We determined to try the cautery to its full extent. We chained him up in the morning, and penetrated through the skin with the budding-iron. The spasms were dreadfully violent, and he was scarcely able to walk or to stand. This gradually subsided, and then he began to run round and round, and that increased to an extraordinary velocity: he would then lie for a while with every limb in action. The owner then yielded to all our wishes, and he was destroyed with prussic acid. No morbid appearance presented itself in the brain; but, on the inner plate of the right parietal bone, near the sagittal suture, were two projections, one-sixth of an inch in length, and armed with numerous minute spicula. There was no peculiar inflammation or vascularity of any other part of the brain. [We once cured a case quite accidentally, by throwing a pup into a cold stream of water, and making him swim ashore; we do not recommend the plan, although we should be willing to try it again with one of our own dogs. The animal should be forced to swim till nearly exhausted, and wrapped up in blankets on coming out of the water. The intense alarm created in the pup, together with the violent struggle and coldness of the water, all act as revulsives to the disease, which, if purely nervous, may be overcome by these powerful agents. If the dog be weak, and the stomach deranged, the following tonic balls will answer a good purpose: [Symbol: Rx]: Carbonate of Iron. Ground Ginger, ââ, grs. X, made into two pills, one given morning and evening, or more frequently according to the age or size of the animal.--L.] RHEUMATISM AND PALSY.
