HER PERFECT SENSE FOR SOUND 



IN my quest for further tests as to canine abilities, 

 the idea occurred to me that it might be as well 

 to arrive at a greater degree of certainty with 

 respect to sound, that is, inquiring into a dog's 

 memory for sound, and their powers of differentiating 

 one tune from another. In the case of my old dog, 

 I had already observed many things such as inclined 

 those to whom I had related my experiences, to be 

 of opinion that these had to do with the dog's ear. 

 For instance, if I had been away, and returned (either 

 driving or on foot), conversing in low tones with 

 another person, this dog would scream for joy. His 

 voice on such occasions was of quite a special quality, 

 and everybody about the court-yard knew that I 

 must have already passed the tree known as the 

 " Abend Eiche," which stands some hundred metres 

 distant, and the dog was always at that time confined, 

 though in the open. Our conversations on such 

 occasions were always quiet ones, and yet the dog 

 recognized my voice at a distance of a hundred metres. 

 If I happened to return alone and on foot, after an 

 absence of about two days, his cries would start when I 

 had reached half that distance therefore, at fifty metres 

 and Lola would then also hear my step. And here is 

 another example one about which I was at first 

 doubtful, not knowing to which sense it should be
