could have rendered him no assistance if his bull had been ill be¬

My advice will now be briefly stated to those who are hereafter 
to become useful members of the veterinary profession:—Learn, 
by studious, industrious, and unrelaxing attention, to bring your¬ 
selves acquainted with the diseases incident to all classes of do¬ 
mestic animals, and you will be amply rewarded. 
[A portion of Mr. Bottle’s Essay on Bone, and also of the debate 
on that Essay, are given in the Association part of this number, 
embracing the consideration of the diseases of the extremities, 
and of the joints. We now collect, from the communications 
with which we have been honoured since the last month, the 
papers which are connected with this subject, and they are highly

UNSOUNDNESSES NOT NAMED. 
By Professor Stewart, Glasgow. 
I HAVE met, more than once, with several causes of lameness 
which have never, so far as I know, been described. They are not 
mentioned in books, and they are so little known in stables, that 
they have received no name. It is very important to know and 
to remember them in the examination of horses for unsoundness. 
Sprain of the Extensor Pedis of the hind leg is not rare: 1 
mean the tendon, not the muscle. It is seated midway between the 
hock and the fetlock joints on the front of the leg. To the eye it

When slight, the horse goes sound after a little exercise, but he is 
stiff or lame after rest; and much work makes him lamer during 
the next day. I think it may be produced by knuckling of the 
pastern. I have found no treatment of any use but firing and blis¬ 
tering, with four or six weeks' rest. 
Sprain of the Peroneal Tendon, or of the ligament by which it 
is bound to the head of the metatarsal bone, I have seen several 
times. The horse is lame, most frequently on both legs. There is 
some swelling just below the bend of the hock joint, towards the 
outside, and it is tender. 1 do not know how it is produced. I
