seems to arrive at results by intuition, which a child might pose by a row of figures on a slate, while it is solving the laws that link the stars to infinity! But _revenons a nos moutons_, what was the astral attraction that incontestably bound the reminiscences of Mop to the cognominal distinction of Sir Isaac? I had prepared a very erudite and subtle treatise upon this query, enlivened by quotations from the ancient Mystics,—such as Iamblicus and Proclus,—as well as by a copious reference to the doctrine of the more modern Spiritualists, from Sir Kenelm Digby and Swedenborg, to Monsieur Cahagnet and Judge Edwards. It was to be called Inquiry into the Law of Affinities, by Philomopsos: when, unluckily for my treatise, I arrived at the knowledge of a fact which, though it did not render the treatise less curious, knocked on the head the theory upon which it was based. The baptismal name of the old soldier, Mop's first proprietor and earliest preceptor, was Isaac; and his master being called in the homely household by that Christian name, the sound had entered into Mop's youngest and most endeared associations. His canine affections had done much towards ripening his scholastic education. "Where is Isaac?" "Call Isaac!" "Fetch Isaac his hat," etc. Stilled was that name when the old soldier died; but when heard again, Mop's heart was moved, and in missing the old master, he felt more at home with the new. As for the title, "Sir," it was a mere expletive in his ears. Such was the fact, and such the deduction to be drawn from it. Not that it will satisfy every one. I know that philosophers who deny all that they have not witnessed, and refuse to witness what they resolve to deny, will reject the story in toto; and will prove, by reference to their own dogs, that a dog never recognizes the name of his master,—never yet could be taught arithmetic. I know also that there are Mystics who will prefer to believe that Mop was in direct spiritual communication with unseen Isaacs, or in a state of clairvoyance, or under the influence of the odic fluid. But did we ever yet find in human reason a question with only one side to it? Is not truth a polygon? Have not sages arisen in our day to deny even the principle of gravity, for which we bad been so long contentedly taking the word of the great Sir Isaac? It is that blessed spirit of controversy which keeps the world going; and it is that which, perhaps, explains why Mr. Waife, when his memory was fairly put to it, could remember, out of the history of the myriads who have occupied our planet from the date of
