Many animals, however, certainly sympathise with each other's distress or danger. This is the case even with birds. Captain Stansbury found on a salt lake in Utah an old and completely blind pelican, which was very fat, and must have been well fed for a long time by his companions. Mr. Blyth, as he informs me, saw Indian crows feeding two or three of their companions which were blind; and I have heard of an analogous case with the domestic cock. We may, if we choose, call these actions instinctive; but such cases are much too rare for the development of any special instinct. I have myself seen a dog, who never passed a cat who lay sick in a basket, and was a great friend of his, without giving her a few licks with his tongue, the surest sign of kind feeling in a dog. Captain Stansbury found a fat, blind pelican; Darwin himself saw a dog lick a cat. On such slender pillars is modern science balanced.
