The point of interest is that a profusely stripeddam belonging to an ancient wild species should have pro-duced an obscurely striped foal to a cross-bred pony, theancestors of which have long been under domestication. It thus appears that parents devoid of stripes may havemore or less striped offspring; that all foals do not passthrough a striped stage during development; that foalsmay lose the majority of their stripes soon after birth, andthat though one of the pai^ents is striped all over, the Fig. Skiu of the Dam of Lady Meux. three Hybrids. offspring may only possess faint indications of zebra-likemarkings. Having seen that foals have often stripes at birth whichafterwards disappear, the question of so vital importancein connection with telegony may now be asked : Are thestripes often found on foals due to reversion or atavism ?A direct answer to this question is of course impossible,but an answer sufficiently convincing may be arrived at bythe deductive method. It seems to be admitted that all the breeds of pigeons JI-KGONY AND REVKKSION, 121 have desceiided from the blue rock pigeon {Columba livia),and it has long been known that when distinct varieties ofpigeons are crossed^ the young sometimes very closelyresemble blue, rocks. Mr. Darwin refers to a pigeondescended from a red spot and a white fantail on the oneside, and two black barbs on the other. This pigeon washardly distinguishable in its coloration from a wild rock pigeon. Darwin accounted f
