Summary:
Responds to CD’s new work [Cross and self-fertilisation]. Suggests results might have been more convincing if CD had measured weights instead of heights. The fact that infertile hybrids have not been produced means that the "one great objection" has not been got rid of: the physiological characteristic of species. Suggests an experiment to produce "sterile mongrels" which would remove objection.
