We now pass to the experiments made at Penycuik in crossing the zebra Matopo with various mares of different breeds: 1. Matopo was first mated with Mulatto, one of Lord Arthur Cecil’s black West Highland ponies. The result was the hybrid Romulus (see p. 132), which on the whole, both in mental disposition and bodily form, takes more after his father than his mother. His striping is even more marked than that of his sire. He has a semi-erect mane which has been shed annually. The pattern of the markings, on both body and face, resembles the stripes on a Somali zebra--which, as we have seen, is regarded by Professor Ewart as the most primitive type--more than they resemble that of any of Burchell’s zebras. The profuse striping is a point of difference between this hybrid and Lord Morton’s. The quagga-hybrid was less striped than many dun-colored horses. The mother Mulatto was next mated with a highly bred gray Arab horse, Benazrek. The offspring agrees in all respects with ordinary foals; it had, however, a certain number of indistinct stripes, which could only be detected in certain lights. The stripes were not nearly so clear as in a foal bred by Mr. Darwin from a cross-bred bay mare and a thoroughbred, and they disappeared entirely in about five months. [Illustration: ROMULUS, TWENTY-SEVEN DAYS OLD.] Recently Mulatto has produced a third foal to Loch Corrie, a sire belonging to the Isle of Rum group of West Highland ponies, and closely resembling his mate. This foal was about as much striped as its immediate predecessor. In both cases the pattern of the stripe differed not only from that of Matopo, the previous sire, but from that of the hybrid Romulus. These two foals seem to lend some support to telegony; but the evidence which might be drawn from the second of them is destroyed by the fact that the sire Loch Corrie has produced foals from two West Highland mares, one brown and one black, and each of these foals has as many and as well marked stripes as the foal of Mulatto. 2. Four attempts were made to cross the zebra with Shetland ponies; only one succeeded. The hybrid was a smaller edition of Romulus. The dam Nora had been bred from before, and had produced, by a black Shetland pony, a foal of a dun color which was markedly striped. After the birth of the hybrid she was put to a bay Welsh pony; the resulting foal had only the faintest indication of stripes, which soon disappeared. It is a remarkable fact that Nora’s foals were more striped before she had been mated with the zebra than afterward.
