CROSS BREEDING.

dark pasterns, or the narrow stripes on the forehead, with which 
the quagga is marked. They have no appearance of the dark hair 
along the belly, or of the white tufts on the sides of the manes. 
Both the manes are black, and that of the filly is short and stiff, 
and stands upright ; and Sir Gore Ouseley’s stud-groom alleged, 
that it never was otherwise. That of the colt is long, but so stiff 
as to arch upwards and to hang clear of the sides of the neck, 
in which circumstance it resembles that of the hybrid. This is 
the more remarkable, as the manes of the Arabian breed hang lank 
and closer to the neck than of most others. The bars across the 
legs, both of the hybrid and of the colt and filly, are more strdngly 
defined and darker than those on the legs of the quagga, which are 
very slightly marked ; and though the hybrid has several quagga 
marks which the colt and filly have not, yet the most striking, 
namely, the stripes on the forehand, are fewer and less apparent 
than those on the colt and filly. These circumstances may appear 
singular ; but I think you will agree with me, that they are trifling 
compared with the extraordinary fact of so many striking features 
which do not belong to the dam being communicated in two suc- 
cessive instances; communicated through her to the progeny not 
only of another sire, who also has them not, but of a sire belonging, 
probably, to another species — for such we have strong reason for 
supposing the quagga to be. 
I am, my dear sir, 
Your faithful humble servant, 
Morton. 
Dr. W. H. Wollaston. 
P.S. I have requested Sir Gore Ouseley to send me some 
specimens of hair from the manes of the sire, dam, colt, and filly ; 
and I shall write to Scotland for specimens from those of the 
quagga and of the hybrid. 
I am not apt to build hypotheses in a hurry, and have no predi- 
lection either for or against the old doctrine of impressions pro- 
duced by the imagination; but I can hardly suppose that the 
imagination could pass by the white tufts on the quagga’s mane 
and attach itself to the coarseness of its hair. 
Wimpole Street, August 12th, 1830. 
Note by Dr. Wollaston. 
By the kindness of Sir Gore Ouseley, I had an opportunity of 
seeing the mare, the Arabian horse, the filly, and the colt, and of 
witnessing how correctly they agreed with the description given of 
them by Lord Morton. 
Having, shortly afterwards, described the circumstances to my
