In the margin is written “Retriever killing one bird.” This refers to the cases given in the Descent of Man, 2nd Ed. (in 1 vol.) p. 78, of a retriever being puzzled how to deal with a wounded and a dead bird, killed the former and carried both at once. This was the only known instance of her wilfully injuring game.
