From George Brown [before 1868]¹

[Down.]

[Mr. G. Brown, of the Cirencester Agricultural College, who has particularly attended to the dentition of our domestic animals, writes to me that he has “several times noticed eight permanent incisors instead of six in the jaw.”]²

The date is established by the publication of this fragment in Variation 1: 50; Variation was published early in 1868 (see Correspondence vol. 16).
