To complete this short preamble, it is right to add that, for some time past, the case of the Elberfeld horses no longer stands quite alone. There exists at Mannheim a dog of a rather doubtful breed who performs almost the same feats as his equine rivals. He is less advanced than they in arithmetic, but does little additions, subtractions and multiplications of one or two figures correctly. He reads and writes by tapping with his paw, in accordance with an alphabet which, it appears, he has thought out for himself; and his spelling also is simplified and phoneticized to the utmost. He distinguishes the colour in a bunch of flowers, counts the money in a purse and separates the marks from the pfennigs. He knows how to seek and find words to define the object or the picture placed before him. You show him, for instance, a bouquet in a vase and ask him what it is. "A glass with little flowers," he replies. And his answers are often curiously spontaneous and original. In the course of a reading-exercise in which the word Herbst, autumn, chanced to attract attention, Professor William Mackenzie asked him if he could explain what autumn was. "It is the time when there are apples," Rolf replied. On the same occasion, the same professor, without knowing what it represented, held out to him a card marked with red and blue squares: "What's this?" "Blue, red, lots of cubes," replied the dog. Sometimes his repartees are not lacking in humour. "Is there anything you would like me to do for you?" a lady of his acquaintance asked, one day. And Master Rolf gravely answered: "Wedelen," which means, "Wag your tail!" Rolf, whose fame is comparatively young, has not yet, like his illustrious rivals of the Rhine Province, been the object of minute enquiries and copious and innumerable reports. But the incidents which I have just mentioned and which are vouched for by such men as Professor Mackenzie and M. Duchatel, the learned and clear-sighted vice-president of the Societe Universelle d'Etudes Psychiques,[1] who went to Mannheim for the express purpose of studying them, appear to be no more controvertible than the Elbenfeld occurrences, of which they are a sort of replica or echo. It is not unusual to find these coincidences amongst abnormal phenomena. They spring up simultaneously in different quarters of the globe, correspond with one another and multiply as though in obedience to a word of command. It is probable therefore that we shall see still more manifestations of the same class. One might almost say that a new spirit is passing over the world and, after awakening in man forces whereof he was not aware, is now reaching other creatures who with us inhabit this mysterious earth, on which they live, suffer and die, as we do, without knowing why.
