the frequent and fatal concomitant of which is, the presence of 
thousands of worms in the air-passages.” 
The reading of this caused me to give the turpentine a trial, 
and I am happy to inform you that it has quite the desired ef- 
fect. In slight cases I have omitted the tincture of opium, and 
given the spirit and balsam twice a week with evident benefit. 
Generally three doses are sufficient in these cases. I hope ere

a future time you shall hear from me again, with my name and 
address.

HORSE AND THE COW. 
By Mr. W. Mogford, F.N., Guernsey . 
I had intended, as intimated in my last, to hazard some re-

tended to throw out the hint by way of awakening attention to it. 
Of course, after the more minute details which 1 have seen, my 
surmise is entirely out of the question. 
Will you, notwithstanding, permit me to lay before you the 
facts which seemed at first to justify my inference? Although 
not adduced in connexion with the epidemic, I venture to hope 
they will be considered by some of your readers as not altogether 
destitute of interest. 
Some time ago, I was sent for by R. S. Heysham Esq., the 
“ Nimrod” of our island, and one of the best judges of the horse 
I have ever met with. He wished me to see two colts of his which 
he considered exhibited symptoms of suppressed strangles; and 
from the swelling of the maxillary glands, the inflammation of
