INHERITANCE OF ACQUIRED CHARACTERS 169 



result, says : 1 " The first hybrid was born August 12, 

 1896, the dam being Mulatto, a black Highland pony 

 lent by Lord Arthur Cecil." 



" In 1897 Mulatto had a foal to Benazrek, a gray Arab 

 stallion. As this subsequent foal of Mulatto was indis- 

 tinctly striped, I was at first inclined to believe she had 

 been infected by her first sire, the zebra Matopo; but 

 when more richly striped pure-bred foals were obtained 

 later by Benazrek out of Highland mares which had never 

 even seen a zebra, it became evident that Mulatto af- 

 forded no evidence in support of the infection doctrine. 



" Lord Morton's quagga counted for so little in the 

 hybrid out of the chestnut Arab mare that its right to 

 be regarded as a hybrid has been questioned. Matopo, 

 however, proved so impressive that all his hybrid offspring 

 plainly indicated their descent from a richly striped 

 zebra. 



" On the other hand, the subsequent foals (by Arab 

 and other stallions out of the mares which proved fertile 

 with Matopo) differed so profoundly from hybrids (even 

 when, as was sometimes the case, they had bars on the 

 legs and faint stripes across the withers) that they afforded 

 no evidence that the first male influences ' the progeny 

 subsequently borne by the mother to other males.' ' 



Baron de Parana in Brazil produced many zebra 

 hybrids also from a true Burchell zebra, later rearing pure 

 horse foals from mares that had previous zebra hybrids. 

 In no single case did the stripes which did sometimes 

 appear resemble closely the striping of the zebra.
