DOG GENERAL INTELLIGENCE. 453 



thing in exchange, and on every future occasion the latter (who 

 declined being taken in a second time) would put the coin on 

 the floor, and not permit the baker to pick it up until he had re- 

 ceived its equivalent. 



Mr. K. 0. Backhouse writes to me : 



My dog is a broken-haired rabbit- coursing dog, and is very 

 intelligent. I took him one day to an exhibition of pictures and 

 objects of interest, among which were statues and a bust of Sir 

 Walter Scott. It was a local exhibition, and as there was 

 jewellery, some one had to sit up all night with it as guard. I 

 volunteered, and as Ave were looking about and sitting on a 

 stand of flowers, my dog suddenly began to bark, and made 

 as if he had found some one hiding. On looking round I 

 found that it was the bust of Sir Walter Scott standing among

 floor till he reached it, and, seating himself before it, began to 

 bark loudly, as if he would say, ' Why don't you speak to me 1 ' 

 The picture was moved to other parts of the room, and he fol- 

 lowed, seating himself before it and repeating his barking. 



Mr. Charles W. Peach also gives an account in ' Nature ' 

 (vol. xx., p. 196) of a large dog recognising his portrait : 



When it (the portrait) was brought to my house, my old dog 

 was present with the family at the unveiling ; nothing was said 

 to him, nor invitation given to him to notice it. We saw that 

 his gaze was steadily fixed on it, and he soon became excited and
