THE VETERINARIAN, NOVEMBER 1, 1853. 
Ne quid falsi dicere audeat, ne quid veri non audeat. — Cicero. 
A subject of keener interest to the philosopher, the breeder, 
or the Veterinarian, could hardly, perhaps, have been selected 
than the one — “ On the Hereditary Diseases of Horses” — Mr. 
Dun has, at the instigation of the Royal Agricultural Society, 
recently employed his pen on, and thereby succeeded in 
obtaining a prize from that body; who have now, as their 
6 Prize Essay/ published it in their Journal, out of which we 
have taken the liberty, in our last three numbers, to translate 
it, intact, into our own pages. We must remember, that on 
two previous occasions, under circumstances very similar 
and equally creditable to him, has Mr. Dun presented himself 
to the notice of the Agricultural and Veterinary worlds ; he 
having three years ago obtained from the Highland and 
Agricultural Society of Scotland, their gold medal, as a pre- 
mium for his paper “On the prevailing Epizootic in Cattle, 
called Pleuro-pneumonia and subsequently, another pre- 
mium of Ten Sovereigns for a paper “on Murrain, or the 
Vesicular Epizootic on both of which latter occasions, we 
felt it our gratifying duty to compliment Mr. Dun on the in- 
dustry and ability displayed in his c Essays/ Nor do we feel we 
are bound to do less on the present occasion, since, in the paper 
we this month print the third and concluding portion of, 
Mr. Dun has manifestly pursued his present task in the same 
sanguine and persevering spirit of research, with a display of 
ability, theoretical as w r ell as practical, which we entertain 
no doubt w r ill call down upon him no less the admiration of 
his professional brethren than, as it already has done, that of 
the agricultural body for whom it was originally and especially 
written. 
Mr. Dun considers the subject of his e Essay’ under three 
headings : 
1.— General hereditary characters, both healthy and diseased.
