point was reversed. Two little wounds, covered by pale and 
soft granulations, existed on the internal face of the ear, and a 
serous and slightly fetid fluid escaped from them. A straight 
and inflexible probe was introduced into each of them, and pene¬ 
trated to the very base of the conch. 
There was no doubt as to the existence of caries. I advised 
the extirpation of the ear : the owmer consented, and the opera¬ 
tion was performed. 
The two fistulee having been laid open, were lined near their 
termination by a very thin false mucous membrane. They ended 
in a cavity formed by the complete destruction of the cartilage by 
caries. The diseased cartilage was soft and fetid. Some san- 
guino-purulent fluid was found in the cavity. The cartilage was 
destroyed to the very base ; the skin was thin and ulcerated. 
This serious and extensive injury of the cartilage, and its situ¬ 
ation, well explain the want of success that attended every at¬ 
tempt to heal the fistula, and completely justified the having 
recourse to the operation. 
On the seventh day after the operation, the pledget and the 
sutures were withdrawn. A few drops of blood ran from the 
wound, mixed with bloody pus. 
The wound was now^ dressed daily with chloride of lime. On 
the 8th the pus was laudable; on the 9th, the wound looked 
well; on the 14th, the wound was entirely healed, and the horse 
returned to his owner, and recommenced his usual labour.

ON REDWATER IN CATTLE. 
By Mr. J. D. Harrison, F.*S., Lancaster. 
The season when redwater becomes prevalent, at least in 
this neighbourhood, drawing nigh, I have ventured to trespass 
upon the pages of The Veterinarian, and, perhaps, a little 
upon the patience of its readers, whilst offering to their con¬ 
sideration some facts connected with that disease. They may 
operate as a stimulus to the minds of other practitioners in the 
prosecution of further and more accurate research about this 
matter ; and whereby we may hope ultimately to arrive at the 
much-to-be desired object, of a perfect development of the true 
seat of this complaint. There are, and, I trust, always will be 
found, a few veterinary surgeons who do not confine their inqui¬ 
ries to the diseases of horses alone, but are anxious to extend 
the benefits of science, and may 1 not likewise add humanity.
