Cartwright—indeed, we were assured that there could not be; 
and, sent so promptly after the application of our editorial scalpel 
to his last letter, they evinced a good and kindly feeling, which 
we trust will be prevalent through the whole profession. 
And now, having inserted Mr. Hales’s reply to Mr. Cartwright, 
and which he had a right to demand,and truly regardingMr. Hales 
(in the language of Mr. Hickman) as “ an ornament to our pro* 
fession,” and iris pupil Mr. Cartwright (in the language of Mr. 
Hales) as “a very persevering man, to whom great merit is due, 
we trust that all personal controversy between them will cease. 
The question of cataract or of hernia is still open to either of 
them, or to any one, and “ of fair criticism they must aoide the 
ordeal but never, in our Journal, shall “ill-nature supply the 
place of criticism, nor irritable feelings mislead the judgment.

To the Editors of“ The Veterinarian.” 
Perhaps, gentlemen, you will deem the following outline of 
a plan for the ventilation of a stable scarcely worth inserting in 
your valuable periodical. I should not have ventured to submit 
it to you, had it not been much approved of by Captain Piper, 
of the Royal Engineers, who expressed to me his intention to 
attempt its introduction into the barrack stables at Manchester. 
Moreover, 1 saw the subject on the tapis in the last Veteri¬ 
narian ; and a further inducement has been, that it may, per¬ 
haps, call forth a better contrivance from the pen of some one

My plan is this -Suppose a stable to be blocked up by 
other buildings on all sides except at its two ends; in that case 
I pronose to have a large wooden tunnel, two feet square, 
runnino- the whole length of the stable under the mangers; and 
if it should be a double stable, one tunnel under each row of 
man°ers. These conduits are to come through the end walls of 
the stable, and to be open at both ends on the outside, foi the 
purpose of admitting a thorough draught or body of air through 
them. This main stream of air is to be equally dispersed about 
the stable by means of perpendicular wooden shoots or chimneys, 
six inches square, emanating out from this main tunnel, one at 
the head of each stall-partition. They should be seven or eight 
feet hi°‘h, so as to avoid a draught on the hoise s eyes, anci 
open af their tops like chimney pots, and should stand out two
