ORDER OF PACHYDERMATA. 
223 
The resemblance which exists between the Ass and the Zebra 
suggested the idea that a cross might easily be made between 
them. Mules between the Zebra and the Ass were obtained 
in England in the time of Buffion, and, at the present day, mules 
between the Zebra and the Horse. 
The Zebra was not unknown to the ancients, who called it 
Hippo-tigris, that is Horse-tiger. An historian relates that the 
Emperor Caracalla killed on a certain day, in one of the circus 
combats, an Elephant, a Bhinoceros, a Tiger, and a Hippo-tigris. 
Diodorus of Sicily speaks of the Hippo-tigris, although in rather 
obscure terms. 
The kings of Persia, during certain religious festivals, were 
accustomed to sacrifice Zebras to the sun, a stock of which were 
kept by these potentates in some of the islands of the Bed Sea. 
Quagga . — The Quagga is smaller than the Zebra, and more 
resembles the Horse in general shape. His head is small, and 
his ears are short. The colour of head, neck, and shoulders is a 
dark brown, verging on black ; the back and the flanks are of a 
bright brown, which on the croup merges into a russet grey. The 
upper parts of the legs and tail are crossed with whitish bars, the 
underneath parts are white. The tail is terminated by a tuft of 
long hair. It is a native of the plateaux of Caffraria, and feeds 
on grasses and the Mimosa shrub, and lives in droves indiscrimi- 
nately with the Zebra. It is tamed without difficulty. The 
Dutch colonists were in the habit of keeping them with their 
herds, which they defended against the Hyenas. If one of these 
formidable carnivora threatened to attack the cattle, the domes- 
ticated Quagga would attack and beat down the enemy with its 
fore-hoofs, ultimately trampling it to death. 
The menagerie of the Museum of Natural History in Paris has 
for some time been in possession of a male Quagga. At the sight 
of Horses or Asses, this animal would several times utter a shrill 
cry, which might be pretty nearly expressed by the word Coua-ag ! 
Dauw or Peetsi (. Equus Burchellii, Bennett). — The Dauw seems 
to take a middle place between the Zebra and the Quagga. It 
resembles the former in its shape and proportions, and the latter 
in the colour of its coat, which is dun on the upper and white 
on the underneath portions of the body. All the upper parts are 
streaked with dark bands, which are transverse in front and oblique
