A SINGULAR REMOVAL OF A BONY CALCULUS. 
By Mr. Thos. Harold, Wicklow , Ireland. 
HAVING been a constant reader of your valuable Journal for 
many a year, and admired the principle on which it has been car- 
ried on, I beg leave to give you the following singular case, as I 
have never read of or seen such a case before : it may not be unin- 
teresting to the readers of your valuable publication. 
In March 1840, a farmer led a three-year-old filly to my 
infirmary by means of a rope tied round her neck, as she would 
not allow any person to approach her head to halter her. I was 
surprised to see a lump of the size of a man’s hat at the bottom of 
the ear. I inquired of the owner what was the cause of it, when 
he told me that he perceived a small lump in the same place when 
she was only eight days old, and that it had been gradually in- 
creasing until this time, with a constant weeping of something like 
red water. He also stated that he had taken her to different farriers 
but none would have any thing to do with her. At length he 
brought her to me. I went up to her, thinking that I should 
examine what was the matter, when she suddenly struck at me 
with her fore feet. I then found it necessary to put her into my 
break, and confine her in the usual way. Even then I found it im- 
possible to examine her in the proper way ; I, therefore, put on the 
hobbles and cast her in my pit-fall, and had the head confined. I 
made an incision in the lump five inches deep, and five in width, 
thinking there might be some matter beneath ; but to my surprise I 
found none. I took one of my dissecting knives and cut the lump 
clean off; and then found a black spot, about the size of a hen’s egg, 
covered with a gristly substance, and with a hole in the centre that 
would admit the head of a calking pin. Fearing that I might 
interfere with the nerve, I proceeded cautiously with a small lancet, 
still expecting matter, and seeing none. I put in my finger, and 
felt something hard. I got my finger under it and forced it up, and 
found it to be a round bone, quite smooth on the surface, and about 
the size of a walnut : I have it still. It would be an acquisition to 
your museum. 
I then applied the following : viz. sulph. alumin. J ss > sulph. 
cupri 3ij, spts. vini §iv, sapon. moll. 3ij, a small portion to be ap- 
plied twice a-day. 
In thirty days she was fit for training ; and in six months after- 
wards she was brought to the fair of Enniscorthy and sold to an Eng- 
lish gentleman for fifty guineas, and passed as sound by a Wexford 
veterinary surgeon.
