[19] Remarkable experiments on this question have lately been carried out by R. H. Compton (Camb. Phil. Soc., XV, 1910, p. 495), showing that in a certain Barley, "Plumage Corn," the average ratio of left to right is about 1.5. A fuller paper has since been published by Compton, Jour. Genetics, 1912, II, I, p. 53.
