to take her to the bull. Her horns are only just budding, so 
that she could not be tied up in the byre, but was allowed to be 
loose. 
Did you ever know an instance of a calf seeking the bull so 
young ? The queys of this country commonly take calf from 
three to Jive years old : and do you consider it possible that she 
can conceive ? 
If you can find leisure, I should feel much obliged by your 
answering my present communication. 
With feelings of respect, I am, 8cc. 
P.S. The calf in question is entirely red, and beautifully 
formed ; the only blemish I can find is in her ears, which are 
marked naturally, the tips off, and a deep slit in each ear. 
[We do not recollect hearing of a quey calf seeking the bull 
at so early an age; but it is not unusual for very young females 
to have a desire for the male. It is probable that she is not 
impregnated ; but if she is, we scarcely think it possible for 
her to produce the calf and live.—D.]

Diseases of the Eyes. 
The diseases to which the eye of the domesticated horse is 
obnoxious, when compared in number with the many set down 
by ophthalmic writers to this organ in man, are very few. But 
there is one among them that has proved, in every period of 
veterinary medicine, so fatal to vision, and, even at the pre¬ 
sent day, so obstinately pursues it course, in spite of remedial 
means, that it offers, in my humble opinion, a sufficient induce¬ 
ment for us to become well acquainted with the structure and 
physiology of this organ, and to pay more attention to it in a 
state both of health and of disease. 
To an experienced veterinary oculist the aspect of health is so 
familiar, and the ordinary imperfections so striking, that he pro¬ 
nounces the organ, at the first glance into its interior, to be either 
sound or unsound, and here the inquiry too frequently ends. There
