Among social and communal animals the sentiment of sympathy widens to embrace all the members of the tribe, a characteristic which is very strongly manifested in so low an organism as the ant. As an example of this feeling among birds, Romanes quotes an interesting illustration from Edward, the naturalist. The latter had shot and wounded a tern, but before he could reach it, the helpless bird was carried off by its companions. Two of these took hold of it by the wings and flew with it several yards over the water. They then relinquished their burden to two others, and the process continued in this way until they at length reached a rock at some distance. When the hunter, eager for his prize, pursued them, the sympathetic birds again took up their wounded companion and flew off with it again over the water. Abundant instances of this sentiment of social affection could be quoted from the mammalia. It is by no means confined to members of a species, but may extend to very unlike species. No one needs to be told of the warm affection so often shown by the dog for its master, a love which will lead it to dare wounds or death in his service, or in the protection of his property. This altruistic sentiment strongly exists in the monkeys. Examples of the ardent feeling of these animals for their fellows have been given in a preceding chapter, and many more might be quoted, if necessary. It must suffice here to quote a single further instance cited by Romanes, and relating to a small monkey which was taken ill on shipboard, where there were several others of different species. "It had always been a favorite with the other monkeys, who seemed to regard it as the last born and the pet of the family; and they granted it many indulgences which they seldom conceded to one another. It was very tractable and gentle in its temper, and never took advantage of the partiality shown to it. From the moment it was taken ill, their attention and care of it redoubled; and it was truly affecting and interesting to see with what anxiety and tenderness they tended and nursed the little creature. A struggle often ensued between them for priority in these offices of affection; and some would steal one thing and some another, which they would carry to it untasted, however tempting it might be to their own palates. They would take it up gently in their forepaws, hug it to their breasts, and cry over it as a fond mother would over her suffering child."
