(4) One which I shot at, and missed in the ling, bolted straight for a hole, as though accustomed to it, and I never knew a hare to go to ground in that ready way. (5) A tradition has long attached to the Moor that the hare and rabbit do occasionally inter-breed. Mr. Heape replied:—“I am aware that many naturalists deny that hares and rabbits will breed together. I am not, however, myself of that opinion, but I never had satisfactory proof of such a cross occurring.” Further enquiry led to the following facts:—In the year 1773 the Abbe Domenico Gagliari got two litters from a female hare by a male rabbit. Richard Thursfield also got hybrid’s of these two species. M. Roux, in 1847, established a breed of “Leporides” in Angonleme, where he bred largely hybrids of hares and rabbits, and these hybrids were fertile with both parent species and among themselves. Baron de Gleichen states that at Hoching, Canton de la Prusse, Polonaise, hybrids of hare (female), and rabbits (male) are generally known. He says, however, that M. Brocca, the French savant, states that there are anatomical differences between hare and rabbit which make it, antecedently, improbable that they should inter-breed. I have myself shot three of these hybrids on the Ostler Ground, and have one of them stuffed. In the year 1897 Sir Henry Hawley shot a similar specimen in Haltham Wood, some five miles from Woodhall; more recently (Oct. 4th, 1898), the Rev. C. E. Chapman, then rector of Scrivelsby, shot another in New York Fen; one was occasionally seen on the Ostler Ground in 1898, and one was mentioned in “Land and Water,” March 5, 1892, as having been shot on the Moors, at Parkend, in Northumberland. I may add that a cross between a rabbit and guinea pig is in the possession of a person at Horncastle; and I have lately heard of a cross between black game and the capercailzie in Scotland. But the following somewhat analogous cases have created special interest. Professor Ewart, of Edinburgh, has bred a cross between a male Berchell’s zebra and a mare pony, of the Isle of Rum breed, half wild, lent for the experiment by Lord Arthur Cecil. The pony was jet black; the foal resulting, except over the hind quarters, had as many stripes as the zebra sire, the stripes being fawn colour, with background nearly black. In form it closely resembled a well-bred foal. As another interesting case of a similar kind, Lord Morton has bred a cross between a male quagga and a nearly pure-bred Arab mare; and Lord Tankerville has, more than once, bred a cross between the famous wild Chillingham bull (Bos Urus Primigenius) and a shorthorn cow.
