Hybridity in Animals. 43 
jection can well be made, when it is considered that the Gayal 
(Bos gavecus) produces a mixed race with the domestic animal; 
and that the yak of Tartary, (Bos grunniens,) and. even the 
American bison, are equally reported to mix with that species, 
notwithstanding their anatomical differences, and that the times 
‘of gestation are not similar.’* 
‘The hybrid offspring of the buffalo and the common. breed of 
cattle, is now familiar in the western parts of the United States, 
particularly i in Missouri and Kentucky ; but I have not been in- 
formed whether they have ever bred away among themselves, or 
with either of the parent stocks. I have instituted 4 inquiries on 
this subject, the results of which I hope to add as a sequel to this 
memoir. In fact, it is now conceded that all the species of the 
genus Bos are similarly circumstanced +; whence we have no 
difficulty in supposing that among the ox tribe, as among various 
other classes of animals, hybridity has more or “09 modified their 
forms during: the oe lapse of thousan 
Bovine and Cervine Hybrid ?—The een sDaienes incidentally 
mentions in his memoirs, the following circumstance that occurred 
during his residence at the Bay de Croc, in Newfoundland : “The 
Carabon (Cervus Wapiti) the houses. 
night, one of them broke into our sheep-fold, — we had a 
cow, that became pregnant by him. She no doubt produced a_ 
mongrel ; but I lost the opportunity of aacnisttening: the fact, be- 
cause she was taken back to Brest.” 
[see no reason to question any part of "this statement, which 
ceases to astonish us when we regard. the 
nomena that are now fully authenticated, on among others the 
nie very remarkable one. 
and Ovine Hybrid.—In the urticke on hybridity, in 
Brande’s 1 Dictionary of vei and Science,$ it is mentioned, 
without doubt or reservation, that a mule has been obtained be- 
tween the bull and sheep; a statement that claims our entire 
credence, from the circumstance that the physiological part of 
of. work in which it is contained, is from the pen of Prof. Ones 
the Royal College of Surgeons
