Further, I give an observation of my own (p. 445) on one terrier making a gesture-sign to another. Terrier A being asleep in my house, and terrier B lying on a wall outside, a strange dog, C, ran along below the wall on the public road following a dog-cart. Immediately on seeing C, B jumped off the wall, ran upstairs to where A was asleep, woke him up by poking him with his nose in a determined and suggestive manner, which A at once understood as a sign: he jumped over the wall and pursued the dog C, although C was by that time far out of sight, round a bend in the road. On page 447 I give, on the authority of Dr. Beattie, the case of a dog which saved his master’s life (who had fallen through the ice, and was supporting himself with a gun placed across the opening), by running into a neighbouring village, and pulling a man by the coat in so significant a manner that he followed the animal and rescued the gentleman. Many cases more or less similar to this one are recorded in the anecdote books. Concerning the use of gesture-signs by monkeys, I give on page 472 the remarkable case recorded by James Forbes, F.R.S., of a male monkey begging the body of a female which had just been shot. “The animal,” says Forbes, “came to the door of the tent, and, finding threats of no avail, began a lamentable moaning, and by the most expressive gestures seemed to beg for the dead body. It was given him; he took it sorrowfully in his arms and bore it away to his expecting companions. They who were witnesses of this extraordinary scene resolved never again to fire at one of the monkey race.” Again, Captain Johnson writes of a monkey which he shot upon a tree, and which then, as he says, “instantly ran down to the lowest branch of a tree, as if he were going to fly at me, stopped suddenly, and coolly put his paw to the part wounded, covered with blood, and held it out for me to see. I was so much hurt at the time that it has left an impression never to be effaced, and I have never since fired a gun at any of the tribe. Almost immediately on my return to the party, before I had fully described what had passed, a Syer came to inform us that the monkey was dead. We ordered the Syer to bring it to us; but by the time he returned the other monkeys had carried the dead one off, and none of them could anywhere be seen” (p. 475).
