In the _Spectator_ of April 21st there is an article on Apes, in which the following occurs:--"Monkeys, we believe, alone among animals can recognise the meaning of a picture." It may interest some of your readers to hear that certain other animals can also do this, two instances having come under my own observation. A cat belonging to a little girl I know was on the child's bed one morning, and made a spring at a picture of a thrush, about life-size, which was hanging near. The other case is that of a dog--a female Irish terrier--who is in the habit of running with her mistress's pony carriage. When she sees the pony being harnessed, she often shows her delight by jumping up at its head and barking. In a certain shop to which she sometimes goes with her mistress there is a picture of a horse hanging. The dog invariably behaves in exactly the same manner to this, jumping up and barking at it, thus showing unmistakably that she recognises its meaning. JULIA ANDREWS. _May 19, 1894._ The following instance bears on the subject discussed in the _Spectator_ of May 5th. We had for a newcomer to our circle a little terrier dog. I was informed it had been seen in the library facing a large-sized portrait of myself, and barking furiously. I was somewhat sceptical until a day or two later I saw it repeat the performance. I have wondered whether it was because the dog thought it a good or bad representation of the original, and so was complimenting or otherwise the artist. FRANK WRIGHT. [_May 19, 1894._] Apropos of the recognition of pictures by dogs (_Spectator_, May 5th), I think you may be interested in the two following facts which came under my notice a few years ago. A sagacious but quite uneducated old terrier came with his master to call for me, and coiled himself on the hearthrug while we talked. Turning himself round in the intervals of slumber, his eye caught an oil-painting just over his head (a life-size half-length of a gentleman). He immediately sat up, showed his teeth, and growled--not once, but continually--as both angry and mortified that neither eyes nor nose had given him notice of the arrival of a stranger! The next instance was similar, except that the chief actor was a young, intelligent collie, who, on the sudden discovery of a man looking at him from the wall, barked long and furiously. In both instances, after their excitement had subsided, I led the dogs to look at another picture similar in size, and also of a gentleman, but neither of them would take the smallest notice of it. I need only add that the picture which the dogs appreciated was painted by Sir Henry Raeburn--the other was not. Might not a few sagacious canine members be a useful addition to the Royal Academy Hanging Committee? B. THOMSON. [_May 26, 1894._]
