DOG— GENERAL INTELLIGENCE.

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 w^as 
jewellery, some one had to sit up all night with it as guard. I 
volunteered, and as we 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 
the flowers, and in which he evidently recognised sufficient like- 
ness to a human being to think the supposed man had no 
business there at so late an hour. 
I adduce this instance because it serves as a sort of in-

faculty, namely, of recognising portraits as representing 
persons, or possibly of mistaking portraits for persons. 
Mr. Crehore, writing to 6 Nature 5 (vol. xxi., p. 132), 
says : —

seen. It was placed upon the floor leaning against the wall. 
In the words of my informant, who witnessed it, the dog, when 
he suddenly caught sight of the picture, crouched and trembled 
all over, his whole body quivering. Then he crept along the 
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 % * 
The picture was moved to other parts of the room, and he fob 
lowed, seating himself before it and repeating his barking. 
Mr. Charles W. Peach also gives an account in 6 Nature 9 
(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
