NEW THEORY ON THE 
light to which they are exposed ?—until all impatience of light 
has vanished, and the organs have resumed an appearance free 
from disease. 
I say, that until we have effected this, our treatment with 
every necessary precaution should be strictly persevered in ; and 
if the proprietor of our patient does not chuse to afford us every 
opportunity, and strictly abide by the instructions we give, he 
cannot attach any blame to the practitioner, or question his 
ability. If we are not able at the present to accomplish this de¬ 
sideratum, we ultimately shall be. Whenever a discovery is 
made in the works of Nature, we observe no complication in her 
mechanism—no mysterious principle in her laws and economy. 
It is unworthy the name of science to give a disease we cannot 
at present control, the appellation specific, gouty, &c.; it can 
only serve to sheathe our ignorance as to its successful mode of 
treatment, and to stifle the inquiry of our employers, but can 
never shield our consciences from unpleasing reflection. 
Now that I am communicating with The Veterinarian, I 
take this opportunity to return Mr. Karkeek my acknowledg¬ 
ments for his reply to my letter published in the February Num¬ 
ber ; and beg leave to inform Mr. Karkeek, that if he will take 
the trouble to read that letter over again, he perhaps may dis¬ 
cover that I did not there state the case of the chestnut mare to 
be one of glanders. Whether or not I made a mistake in the se¬ 
lection of that case as one shewing the efficacy of cantharides, 
Mr. Karkeek may decide if he chooses. Mr. K. gives me 
credit for making a great deal out of nothing; I wish I could 
say as much in his favour, from the perusal of those laborious 
communications on the origin of the horse, breeding, &c., in 
which so much classical set-phrase loquacity is displayed. 
Some for renown on scraps of learning dote, 
And think they grow immortal as they quote. Young. 
But out of a great deal , Mr. Karkeek, you have made nothing. 
I have no future intention to occupy the pages of The Veteri¬ 
narian with unfriendly expressions and unprofitable scribble, 
consequently Mr. K. will please to excuse me in future. 
NEW THEORY ON THE PRODUCTION OF ANIMAL 
HEAT DURING RESPIRATION. 
By Mr. James Turner. V. S. 
The object of these few lines is a speculative attempt, to 
shew that in ordinary respiration caloric , or the principle of heat,
