WILLIAM MACKENZIE) 157 In recording the remarks made and answers given by these dogs I have--wherever it seemed possible to do so without loss of a certain distinctive charm--inserted the English translation _only_; here and there, however, where, for instance, the conversation between mistress and dog has turned on the spelling of a word it has been necessary to give the entire sentence in German. There are also some quaint remarks of which I have been loth to omit the original, these being sure to appeal to anyone acquainted with idiomatic German. THE TRANSLATOR LOLA THOUGHT CAPACITY IN ANIMALS It was in the year 1904 that the first experiments towards understanding an animal's ability to think were brought into public light. Wilhelm von Osten then introduced his stallion Hans II to all who seemed interested in the subject, and the most diametrically opposed opinions were soon rife with regard to the abilities of this horse, to which von Osten maintained he had succeeded in teaching both spelling and arithmetic.
