And here I cannot help mentioning a very ridiculous show of a learned pig, which of late days attracted much of the public notice, and at the polite end of the town. This pig, which indeed was a large unwieldy hog, being taught to pick up letters written upon pieces of cards, and to arrange them at command, gave great satisfaction to all who saw him, and filled his tormenter's pocket with money. One would not have thought that a hog had been an animal capable of learning: the fact, however, is another proof of what may be accomplished by assiduity; for the showman assured a friend of mine, that he had lost three very promising brutes in the course of training, and that the phenomenon then exhibited had often given him reason to despair of success.
