FOOTNOTES:
[1] Excluding 6 doubtful because from too young embryos and not observed by myself.
[2] One is reported as having a I comb; probably the limiting condition, again.
[3] E. g., Pen 813, 935 ♀, embryo from egg of May 13.
[4] I say probably of the duplex type because the cock of pen 769 had a distally split toe on the right foot, reminding somewhat of the reduced triplex type. But as the left foot had a typical duplex thumb, and the triplex is not common in Houdans, it should probably be classed as duplex.
[5] Lewis and Embleton (1908, p. 45) present strong arguments against the theory that syndactylism is due to arrested development.
