USE OF CAMPHORATED SOAP LINIMENT, &C. 181 
from that to 3vi, once or twice during the day, morning and 
evening, appears to be about a medium dose. 
It requires great caution to manage, with safety, the intioduc- 
tion of this medicine into the system. In over-doses it gene 1 ally 
causes sudden death, and often leaves no traces of its injuiious 
effects on dissection. I have remarked, that its deleterious 
operation is very often accompanied with an intermittent pulse, 
it is, therefore, of extreme importance that we be on the alert 
against the approach of this symptom. 
In the course of my practice on glandered horses, I have availed 
mvself very little of the co-operation of local remedies \ not that 
I am averse to their use, or that I hold them in light estimation, 
but that I have studied to repulse the disease, and eradicate it 
from the constitution, rather than stay its invasion for a time, or 
palliate those effects of it which more immediately come undei 
our notice. 
Having thus summarily unfolded to the Society a statement of 
the effects of barytes, and its various preparations, when adminis¬ 
tered to horses suffering from glanders and farcy, I hope it may 
lead to some repetition of the experiments, therein contained, 
among such of the members as have the opportunities j by any 
of whom it will, at all times, give me great satisfaction to be in¬ 
formed of the results, whether successful or unsuccessful. 
In closing this paper, let me be once more allowed to confess, l 
am not sanguine of success; my late experiments have not shown 
that favouring complexion exhibited by those instituted six or 
seven years ago i whether this be ascribable to a iclinquishment 
of the preparation for the earth itself, I cannot say.

DISPERSING TUMOURS. 
To the Editors of “ The Veterinarian .” 
Gentlemen, 
WHEN I sent the case of incontinence of urine in the horse to 
the Lancet Office, I was altogether unacquainted with the exist¬ 
ence of such a journal as “ The Veterinarian.” I have since 
procured it, and consider it, without flattery, a work of very great 
utility to the profession and the public ; a publication which has 
long been wanting, and a vehicle by which the variety of sentiments 
in the profession might be circulated. Your periodical will tend
