3. Five Icelandic ponies were mated with Matopo, of whom one produced, in 1897, a dark-colored hybrid. The dam, Tundra, was a yellow and white skewbald which had previously produced a light bay foal to a stallion of its own breed. Her third foal (1898) was fathered by a bay Shetland pony, and in coloration closely resembled its dam. There was no hint of infection in this case. This year Professor Ewart has bred from this mare, by Matopo, a zebra-hybrid of a creamy-fawn color, and so primitive in its markings that he believes it to stand in much the same relation to horses, zebras, and asses as the blue-rock does to the various breeds of pigeons (see illustration). [Illustration: TUNDRA (AN ICELAND PONY), HER FOAL, CIRCUS GIRL (BORN 1898), AND HER HYBRID FOAL, SIR JOHN (BY MATOPO), WHEN A MONTH OLD (BORN 1899).] 4. Two Irish mares, both bays, produced hybrids by Matopo, and subsequently bore pure-bred foals. One of the latter was by a thoroughbred horse, the other by a hackney pony. The foals were without stripes, and showed no kind of indication that their mother had ever been mated with a zebra. 5. Although Professor Ewart experimented with seven English thoroughbred mares and an Arab, he only succeeded in one case. The mare produced twin hybrids, one of which unfortunately died immediately after birth. This summer the same mare has produced a foal to a thoroughbred chestnut; “neither in make, color, nor action” does it in any way resemble a zebra or a zebra-hybrid. 6. A bay mare which had been in foal to Matopo for some months miscarried. Here--if there is anything in the direct infection theory--the unused germ-cells of the zebra had a better chance than usual of reaching the ova from which future offspring are to arise, yet neither of the two foals which this mare subsequently produced to a thoroughbred horse “in any way suggests a zebra.” The above is the record of the successful experiments which have been tried at Penycuik, with a view of throwing light on the existence of telegony in the _Equidae_. Experiments have also been made with other animals, such as rabbits, dogs, pigeons, fowls, and ducks. Space allows us to quote but one. Six white doe rabbits, all of which had borne pure white offspring to white bucks, were crossed with wild brown rabbits. The result was forty-two young rabbits, all of a bluish-black color, which in a very short time turned to a brown. These, at the time of writing, were about half grown, and Professor Ewart tells us that it is almost impossible to distinguish them from a full-blooded wild rabbit kept in the same inclosure. The half-breeds, however, were tamer and slightly lighter in color. The mother does next bred with white bucks again, and in every case bred true. The pure white young showed no trace of throwing back to a previous sire.
