The following short note gives the preliminary results of an experiment which I have commenced on a small scale on my father's farm at Field Dalling, near Holt, in Norfolk.

The object of the experiment is to follow out the inheritance of various characters in sheep. In the autumn of 1903 my father placed at my disposal 30 of his Suffolk ewes. Suffolk sheep of both sexes are characterised by black faces and the absence of horns. I determined to cross them with a Dorset ram, Dorsets having in both sexes white faces and large horns. For the present, characters other than horns and face-colour are neglected.
