A pair of goldfinches who had the misfortune to be captured, together with their nest and six young ones, were placed in a double cage, with a pair of canaries, which had a brood of young; there was a division of wirework between the cages. At first the goldfinches seemed careless about their young ones; but the cock canary, attracted by their cries, forced itself through a flaw in the wires, and began to feed them; an operation which it continued regularly, until the goldfinches undertook the office themselves, and rendered the humanity of the canary no longer necessary.
