practical article on this subject in 'Gard. Chronicle,' 1856, p. 620. I
could add a vast number of references, but they would be superfluous.

[83] Koelreuter gives cases in his 'Dritte Fortsetzung,' 1766, s. 53, 59;
and in his well-known 'Memoirs on Lavatera and Jalapa.' Gaertner,
'Bastarderzeugung,' s. 437, 441, &c. Naudin, in his 'Recherches sur
l'Hybridite, Nouvelles Archives du Museum,' tom. i. p. 25.

[84] Quoted by Mr. Sedgwick in 'Med.-Chirurg. Review,' April, 1861, p. 485.
Dr. H. Dobell, in 'Med.-Chirurg. Transactions,' vol. xlvi., gives an
analogous case, in which, in a large family, fingers with thickened joints
were transmitted to several members during five generations; but when the
blemish once disappeared it never reappeared.

'Rejuvenescence,' Ray Soc., 1853, p. 315) apparently holds a similar
opinion.

[100] Sclater, in 'Proc. Zoolog. Soc.,' 1862, p. 163: this species is the
Ghor-Khur of N.W. India, and has often been called the Hemionus of Pallas.

Bengal,' vol. xxviii., 1860, p. 229.

[101] Another species of wild ass, the true _A. hemionus_ or _Kiang_, which
ordinarily has no shoulder-stripes, is said occasionally to have them; and
these, as with the horse and ass, are sometimes double: _see_ Mr. Blyth, in
the paper just quoted, and
