title: Abnormal clutch size in domestic pigeons.
abstract: A strain of racing pigeons has been obtained in which some hens occasionally lay the almost unknown clutch size of three eggs. This effect appears to be due to a simple recessive. Circumstances prevent serious research on the factor and birds are offered free to any workers able to make effective use of them, in order that this extremely rare factor not be lost.
