Further note on the transplantation and growth of mammalian ova within a uterine foster-mother

Abstract

In 1890 I recorded an experiment designed to show that it is possible to make use of the uterus of one variety of rabbit as a medium for the growth and complete fœtal development of fertilised ova of another variety of rabbit. The expeliment was further undertaken in order to determine what effect, if any, a uterine foster-mother would have upon her foster-children, and whether or not the presence, during development, of foreign ova in the uterus of a m other would affect offspring of that in other present in the uterus at the same time. In the experiment above referred to, two fertilised ova were obtained from an Angora doe rabbit which had been inseminated thirty-two hours previously by an Angora buck,, and they were inserted into the fallopian tube of a Belgian Hare doe,, which had been inseminated three hours before by a Duck of the same breed as herself.
