upon the plaister, and the operation is finished. Allow the dress-

About two feet of an old gun-barrel makes an excellent instru- 
ment for opening the cranium. Previous to using it, it should be 
filed to a sharp edge round the end — -the utility of the tube is, 
that when applied to the head, the caloric is going off at the top, 
otherwise it would be determined to the head, and be productive of 
mischief. Sometimes the hydatid is situated underneath the horn, 
and difficult to get at. In this case, the most judicious proceeding 
is to saw off the horn as close to the head as possible, and the 
tumour may be got at with ease. A little more on the diseases 
incidental to sheep shall appear, should they be thought worthy a 
place in your valuable periodical. I remain, &c. 
In cases of hydatid in cattle, I would pursue the same treatment.

CASES OF NEUROTOMY. 
By Mr. C. S. GREEN, V.S., Fareham. 
In the spring of 1839, 1 was sent for to examine a bay mare 
which had been lame for nearly two years. She had ossified car- 
tilages, . and, at the same time, a copious discharge from the frog, 
of a highly offensive character, which was soon cured by the 
application of the common pitch ointment. The lameness, how- 
ever, remained, and the actual cautery and blistering having been 
already tried, the owner wished me to adopt some other treatment, 
and purposed particularly to have her unnerved. I operated on her 
a little above the fetlock, and she got up perfectly sound, and has 
resumed her old station, working on the farm. 
Case II. 
A chestnut mare, that had been lame for twelve months, was 
brought to us in order to be unnerved. My father performed the 
operation at the fetlock-joint. She got up quite sound, and has 
been used as a hack for the last three years, remaining, up to the 
present time, quite sound. I am unwilling to occupy much of 
that valuable work The Veterinarian, but a long time has 
passed since you or your contributors have said one word on this 
most important operation. It is not practised so much as it ought 
to be by the veterinary surgeon, and the farmer and the horse- 
holder do not sufficiently appreciate its value.
