Into that part of the wing formed of the bones of the hand, d to /,are inserted the flight-feathers of the fancier, the primaries of the are ten in number, the second being usually the longest, and the lengthdiminishing regularly from it to the tenth. In some of the more artificial varieties,as the Short-faced Tumblers, the number of primaries is diminished to nine. The secondaries are twelve in number, and take their rise from that part of thewing, c to d, which corresponds to our fore-arm. In some birds a third set ofquill feathers, termed tertiaries, take their rise from the humerus b c, but these
