inferior surface of the neck, under the chest, on both sides of the 
thorax, and over the lumbar region. The condition of the animal 
during this treatment continued unchanged. He was unable to 
move, except with great difficulty, or to lower his head to drink 
from a pail of water, or to pick up food placed on the ground, 
but otherwise his health appeared to be perfect. When Dr. L. 
visited the horse, he found him with a thick swelling all along 
the lower border of the neck, extending down between the fore¬ 
legs and under the chest; and the parts which had been covered 
with mustard, covered with a thick crust, more or less dry, which 
were falling off in spots. Failing to detect any other symptoms, 
and attributing all the symptoms to the peculiar condition of the 
blistered parts, simple treatment for the removal of the scabs was 
directed, with advice to report again in a short time. Early in 
October, the animal being reported to be no better, it was decided 
to have him brought to the hospital, and he was entered on the 
9th instant, having walked down from the place, a distance of 
about fourteen miles. 
When admitted, the horse was in fair condition, and every 
function was normal, except that of locomotion. His head and 
neck were held in an upright position, the inferior border forming 
a convex line forward, and presenting a good example of the 
peculiar formation called “ deer neck.” On the upper cervical 
region the muscles were much atrophied, principally on the left 
side, and at about the middle of the region it seemed as if there 
had been a giving way of some soft structure. The head could 
not be carried downwards, and the lateral motion, either to the 
left or to the right, was very limited and very painful. All his 
movements were awkward, and when called upon to walk, he 
obeyed with great difficulty, and at times as if he had lost partial 
control of his actions. In walking, he moved much like an ani¬ 
mal suffering from laminitis. 
The animal was evidently in a critical condition, and while a 
positive diagnosis was reserved, the state of the superior cervical 
region suggested the possibility of degeneration of some kind, 
either in the muscles or in the ligamentum nuchse, or possibly of 
disease of the vertebrae. 
While under observation, nothing was specially observed beyond
