My Dear Sir, 
I yesterday had an opportunity of observing a singular

Some years ago, I was desirous of trying the experiment 
of domesticating the Ouagga, and endeavoured to procure 
some individuals of that species. I obtained a male; but 
being disappointed of a female, I tried to breed from the 
male quagga and a young chesnut mare of seven-eighths 
Arabian blood, and which had never been bred from : the 
result was the production of a female hybrid, now five 
years old, and bearing, both in her form and in her colour, 
very decided indications of her mixed origin. I subsequently 
parted with the seven-eighths Arabian mare to Sir Gore 
Ouseley, who has bred from her by a very fine black Ara- 
bian horse. I yesterday morning examined the produce, 
namely, a two-years old filly, and a year-old colt. They 
have the character of the Arabian breed as decidedly as can 
be expected, where fifteen-sixteenths of the blood are Ara- 
bian ; and they are fine specimens of that breed ; but both 
in their colour, and in the hair of their manes, they have a 
striking resemblance to the quagga. Their colour is bay, 
marked more or less ke the quagga in a darker tint. Both
