BI-PARENTAL REPRODUCTION 71 



long snout and upright ears, and was striped on the back. 

 It should be borne in mind that the young of the Japanese 

 breed are not striped, and that they have a short muzzle and 

 ears remarkably dependent." 1 "The European wild boar 

 and the Chinese domesticated pig are almost certainly 

 specifically distinct. Sir F. Darwin crossed a sow of the 

 latter breed with a wild Alpine boar which had become 

 extremely tame, but the young, though having half-domestic- 

 ated blood in their veins, were extremely wild in confine- 

 ment, and would not eat swill like common English pigs." 2 



120. " Captain Hutton, in India, crossed a tame goat with 

 a wild one from the Himalayas, and he remarked to me how 

 surprisingly wild the offspring were." 3 



121. "The Earl of Powis formerly imported some thor- 

 oughly domesticated humped cattle from India, and crossed 

 them with English breeds, which belong to a distinct species ; 

 and his agent remarked to me, without any question having 

 being asked, how oddly wild the cross-bred animals were." 4 



122. "I crossed a Dalmatian . . . with a well-bred sable 

 collie, and obtained three pups. . . . The pups neither 

 resemble young collies nor young Dalmatians, but rather 

 suggest young pointers or foxhounds. The ground-colour is 

 nearly white in all three ; in two there are five large dark 

 brown blotches, in one four lemon-coloured patches. This 

 seems to be a case of reversion towards the mediasval ancestors 

 of the Dalmatian." 5 



123. "We have seen in the fourth chapter that the so- 

 called Himalayan rabbit, with its snow-white body, black 

 ears, nose, tail and feet, breeds perfectly true. The race is 

 known to have been formed by the union of two varieties of 

 silver-grey rabbits. Now, when a Himalayan doe was crossed 

 by a sandy-coloured buck, a silver-grey rabbit was produced ; 

 and this is evidently reversion to one of the parent varieties." 6 



124. "There is reason to believe that sheep in their 

 early domesticated conditions were 'brown or dingy black, 

 but even in the time of David certain flocks were spoken of 

 as white as snow. During the classical period the sheep of 

 Spain are described by ancient authors as being black, red, or 

 tawny. . . . The Rev. W. D. Fox was informed that seven 

 white Southdown ewes were put to a so-called Spanish ram 

 which had two small black spots on his sides, and they
