OSSEOUS TUMOUR.

termination in every case of otherwise tractable disease ; but 
in every instance they diminish the chances of successful 
treatment, and necessitate greater watchfulness on the part 
of the practitioner to guard against the prostration to which 
there is so decided a tendency. All depletive treatment 
must be rigidly excluded, anything likely to depress the 
nervous action might cause the already faltering pulse to 
cease at once. 
"When much irritation is present, tincture of opium or 
hyoscyamus are the only narcotics we venture to employ. 
Our febrifuge medicines consist principally of nitrate of potass 
or the carbonate; and tincture of gentian or bark usually 
forms apart of every mixture, when not contra-indicated. 
Fatty degeneration of the fibres of the heart of the horse 
is, as far as we are concerned, a more recent discovery than 
the same disease of liver, arising out of an examination of 
parts sent by Mr. Gowing, whose attention was attracted by 
some peculiar symptoms in a case he had been called to see, 
when the animal’s state precluded any hope of recovery; 
since then we have reason to conclude the malady is as 
common among fat horses as is the “ fatty liver.” 
It will not be necessary to insist further upon these points 
at present, to the exclusion of the subject in hand, but in a 
matter of such importance we may venture to offer some 
remarks at a future time. 
After this digression, which we could hardly avoid, it will 
be desirable to return to the consideration of the diseases of 
the mucous membrane of the respiratory organs, devoting 
our next paper to an examination of those affections which 
may be properly termed inflammatory. 
A COMPACT OSSEOUS TUMOUR CONNECTED 
WITH THE SINUSES OF THE HEAD OF A 
HORSE. 
By B. Cartledge, M.R.C.V.S., Sheffield. 
I send for your inspection an ivory tumour,” with part 
of a horse’s head, to which you will see it was attached by a 
very small pedicle. I have never met with anything of the 
kind before, and, no doubt, such specimens are exceedingly 
rare. I regret that I can give you no further account of it 
than that it was brought to me as you see it by the knacker,
