irritation should require it, tincture of opium or hyoscyamus 
may be added. 
From this combination of tonic and febrifuge medicines 
the happiest results may be expected. 
Among the agents naturally suggested, will be calomel, 
its use, however, is only tolerable when the greatest caution 
is employed. If constipation is present at first, the faeces 
being hard and light coloured, a dose of half a drachm, with 
ten or fifteen grains of opium, may be given and repeated 
with advantage; to the continued exhibition of the drug, 
'however, we cannot but ascribe very disastrous consequences, 
and having regard to the strong feeling which exists in the 
minds of many practitioners of eminence against its use; he 
who employs it must be prepared to risk incurring the 
charge of recklessness in the treatment of cases such as we 
are now discussing. 
An unfavorable termination will be prognosticated if the 
patient continue to refuse food, if the circulation increase in 
frequency, the heart’s action become bounding, the lungs 
more and more obscured, the surface cold, and the counter- 
irritants produce no effect; but should the appetite return, 
the respiration become quiet, the surface warm, and the 
blisters should act with energy, even though the pulse may 
continue for a long time excited and the debility remain, 
there is strong reason to expect ultimate recovery, under 
a judicious continuance of tonic treatment and good 
nursing.

Robinson, M.R.C.V.S., Tamworth; namely, the application 
of the actual cautery to some portion of the larynx or trachea, 
for roaring. 
I have seen some letters on the subject in Bell’s Lifcy 
although I would rather that your excellent Journal had been 
the chosen vehicle for all discoveries connected with our
