DERMITIS. 
443 
The treatment I adopted proved successful ; not that I 
know anything in it is new, or even important, or feel great 
confidence of equal success in future cases of a similar nature ; 
yet from its attendant benefit I feel myself bound to 
record it. 
It consisted in the exhibition of aperients, and blistering 
the forehead and poll, followed by the usual doses of 
belladonna; all the medicines, of course, being given in 
solution. 
It is needless for me to enter further into the minutiae of 
the treatment. It would only be filling your valuable pages 
with uninteresting and useless matter, as every member of 
the profession well knows that one undeviating course of 
treatment cannot be laid down, or indiscriminately adopted 
in all cases of the same class, with the same results. 
I shall, however, be most happy to answ r er any question 
the legalised section of our profession may be desirous to ask, 
respecting this, or any other case published hereafter that 
may emanate from me. 
DERMITIS PRODUCED BY THE PARASITES OF 
POULTRY. 
By James Moon, M.R.C.V.S., Kingston. 
Sir, — Some five or six years since I was consulted respecting 
two carriage-horses, that stood in a stable adjoining a hen- 
house, that were constantly rubbing themselves ; in fact, they 
had to all appearance a confirmed disease of the skin. They 
were dressed, with the Lin. Picis Comp., several times, and 
afterwards with Ung. Hyd. Mit., but without any good effect. 
One night the coachman w r ent into the stable wuth a light, 
when he found not only the horses covered, but the partitions 
of the stalls, with what he supposed to be small lice. This 
discovery at once unveiled the mystery ; the hens were taken 
away, the place well fumigated with sulphur, and the horses 
washed, (which they had been once or twice before,) after 
wdiich they very shortly recovered. No disease of the skin 
has been heard of in the same stable up to the present time. 
The other case happened last year to a brown cart mare. 
The irritation of the skin w^as so great that she would nearly 
rub the partition down between herself and the hens. She 
was dressed, I should say, at least a dozen times with Lin.
