The following is a curious case of tape-worm, by Mr. Reynold:
On an estate where a great quantity of rabbits are annually destroyed in the month of November, we have observed that several dogs that were previously in good health and condition soon became weak, listless, and excessively emaciated, frequently passing large portions of the tape-worm. This induced us to examine the intestines of several hares and rabbits; and, with, very few exceptions, we found each to contain a perfect tape-worm three to four feet in length. We then caused two of the dogs whose cases appeared the worst to be separated from the others, feeding them on potatoes, &c.; and, in eight or ten days, after voiding several feet of the worms, they were perfectly restored to their former strength and appearance. The worm disease, hitherto so formidable to the spaniel and pointer, may in a great measure be fairly attributed to the custom of giving them the intestines of their game, under the technical appellation of "the paunch." The facts above stated, in explaining the cause of the disease, at the same time suggest the remedy.
A worm in the urethra of a dog
. Séon, veterinary surgeon of the Lancers of the Body Guard, was requested to examine a dog who strained in vain to void his urine, often uttering dreadful cries, and then eagerly licking his penis. M. Séon, after having tried in vain to abate the irritation, endeavoured to pass an elastic bougie. He perceived a conical body half an inch long protruding from the urethra with each effort of the dog to void his urine, and immediately afterwards returning into the urethra. He crushed it with a pair of forceps, and drew it out. It proved to be a worm resembling a
strongylus
, four and a half inches long. It was living, and moving about. M. Séon could not ascertain its species. The worm being extracted, the urine flowed, and the dog soon recovered
