have to be allowed for. Comiug to Mulatto's second foal, 

 it may first of all be mentioned that there were no stripes 

 on the face or across the shoulders, nor yet was there a 

 dorsal band; and though there were bars across the legs, 

 the bars were not so pronounced as in many purely-bred 

 foals — foals whose parents had never seen a zebra. More- 

 over, the leg bars were least distinct where they are 

 generally most marked in dun-coloured ponies, i. e. in the 

 vicinity of the knee and hock. There was thus an all but 

 complete absence of the stripes that are ordinarily found 

 in the horse. In Lord Morton's "colts'' besides a dorsal 

 band, there were " dark stripes across the forehead and 

 dark bars aci-oss the back part of the legs/' and stripes 

 across the withers ; in the filly the stripes covered '' nearly 

 the whole of the neck and the back as far as the flanks." 

 There were, in fact, more stripes on the filly than on the 

 quagga hybrid. It seems to me that at least all the 

 stripes found in the filly over and above those in the 

 quagga hybrid must be credited to the black Arabian, 

 and not to the previous sire — the quagga. Why in 

 Mulatto's second foal the stripes were not developed 

 along the spinal ridge and across the withers and hocks, 

 and were specially distinct across the croup and the front 

 of the arm, I am unable to say. That they failed to appear 

 in the usual position, and were more or less distinct in 

 unusual positions, may be considered by some as evidence 

 in favour of " infection." The stripes on the neck and 

 legs need not be specially referred to, but the stripes 

 across the croup and hind quarters deserve ver}^ special 

 consideration. 



In zebra-ass hybrids there are often numerous spots 

 over the croup and hind quarters. These spots were 

 present in a zebra-ass hybrid bred at Windsor during the 

 reign of George IV, and also in a hybrid between an 

 Asiatic ass and a zebra mare bred some years ago in 

 Paris. In Romulus there were, at birth, spots over the 

 croup, but in course of time the spots united to form 

 somewhat zigzag stripes. In one of the 1897 hybrids
