in considering the horse of the Great Gobi Desert to be a mule, 
I decided to breed a number of Kiang-horse hybrids. 1 
With the help of Lord Arthur Cecil, I succeeded early in 1902 
in securing a male wild Asiatic ass and a couple of Mongolian pony 
mares — one a yellow-dun, the other a chestnut. “Jacob,” the 
wild ass, was mated with the dun Mongol mare, with a brownish- 
yellow Exmoor pony, and with a hay Shetland-Welsh pony. The 
chestnut Mongol pony was put to a light grey Connemara stallion. 
Of the four mares referred to, three have already (June) foaled, 
viz., the Exmoor and the two Mongolian ponies. The Exmoor 
having foaled first, her hybrid may be first considered. 
It may he mentioned that the Exmoor pony had in 1900 and 
again in 1901 a zebra hybrid, the sire being the Burchell zebra 
1 Sir William Flower, the late President of the London Zoological Society, 
having more than hinted in 1891 that Prjevalsky’s horse was a mule, one 
would have thought an effort would have been made forthwith to test this 
view in the Society’s Garden.
