the upper provinces, and is also known under the name of palsy 
in cattle.’^ This disease is mostly found among the little farmers, 
to whom it occasions considerable loss. It commences with an 
inflamed state of the pastern joints of the fore leg, and, if 
the inflammation is not suppressed, it forms bony swellings on 
the coronet, pastern, and fetlock joints, besides crooking the 
shank-bone outwards. The animal wastes rapidly away, and 
soon becomes lame in the hip, when it is generally killed. The 
cause of this disease, which appears to be an inflammation of 
the periosteum and softening of the bones, has not yet been dis¬ 
covered. 
Promiscuous Cases of Disease. 
Congenital Blindness. —On careful examination of a blind 
female j)ointer puppy, eight weeks old, both the eyes were 
found to be of their natural size and formation, but the inner 
edge of the iris (Irideremia) was diseased, and the pupil curi¬ 
ously four-cornered, and very small. There hung out of the 
pupil a greyish-white fibrous matter, which appeared to be the 
remainder of the pupillary membrane. Six months afterwards 
we examined this dog, and found that the pupil was considerably 
enlarged, and properly shaped ; the white skin had vanished ; 
in the back-ground of the eye there was a faint yellow green 
light, and the dog not only shewed sensibility to light, but also 
a perception of external objects. 
Knuckling at the Pasterns. —A three-year-old brown mare, 
which had previously fractured the olecranon of the right fore 
leg, remained, after that the broken bones were set, quite stift’ 
at the pastern, so that, when it walked, it trod only on the toe 
of the foot, and consequently the fetlock joint was bent consider¬ 
ably forwards. This continued for almost three years, when an 
empiric undertook the case. He divided the flexor tendon at the 
pastern ; and his treatment was so successful, that, in a few weeks 
after the operation, the mare was cured, and returned to work. 
This false position of the limbs also appeared in six other horses, 
but from different causes. In some it arose from disease of the 
coffin-joint; but in general it proceeded from relaxation of the 
tendons, or their thecte, and therefore must have been treated in 
a very different manner to the successful case abovementioned. 
Roaring dependent on atrophy of the muscles of the larynx :— 
A grey stallion belonging to a carrier, which was brought to us 
with severe inflammation of the larf>;e intestines, and which we 
were afterwards obliged to destroy, was a confirmed roarer. On 
questioning the owner, he admitted that when worked hard his 
horse had always whistled. On dissecting this horse, we found
