fomewhat larger than the quacha, that had longitudinal black 
ftripes on a light ground ; it was grazing among a herd of 
elands. The two brothers having been fome time without food, 
from their anxiety firft to fecure an eland, neglected the ftriped 
animal, intending afterwards to give chace to it ; but his fpeed 
was fo wonderfully fwift, that, bounding towards the mountains, 
he was prefently out of their fight. 
. Martinus Prinflo of Bruyntjes Hoogte, when on a hunting 
excurfion, faw behind the fame mountain feveral wild horfes, 
entirely different from either the quacha or the zebra, but they 
were fo fliy that they never would approach them fufficiently 
near to make minute diftindions ; they appeared to be of a 
light cinereous color, without ftripes. This, however, might be 
a deception of fight arifing from diftance, as dark ftripes upon 
a light ground cannot be diftinguiftied very far ; they form a 
fhade between the two colors, and the lighter tint is predomi- 
nant ; as the primitive colors difpofed in concentric circles on 
a card, and put in motion, will appear white. The black and 
huff zebra, even when very near it, and efpeclally if in motion, 
appears of a dull bluifti afti color, like the common afs. It is 
therefore probable, that the animals defcribed by the three dif- 
ferent perfons, were of the fame fpecies. Vaillant alfo, who 
may generally be depended on, when he fpeaks of animals, 
mentions his having chaced beyond the Namaaquas, day after 
day in vain, an Ifabella colored zebra. This alfo, in all pro- 
bability, was of the fame kind as the others.
