NAVICULAR DISEASE, OF LONG STANDING, IN A HIND FOOT-

DOWN—DEATH. 
By the Same. 
A bay gelding, of seven years old, was found to be lame at 
the first visit of the groom, and Dr. L. was called to see him. 
The animal was standing in his stall, very lame in the off hind 
leg, with lancinating pains, and was with difficulty backed out. 
The shoe was taken off and the foot carefully examined, but 
without detecting anything about that region to account for the 
severe lameness. The appetite was poor, the temperature 102°, 
and pulse about 50, and respiration increased. The visible 
mucous membranes were slightly yellowish, and it seemed that 
some heat and swelling could be detected at the hock and at the 
hip joint. A diagnosis of inflammatory rheumatism was made, 
and the patient was placed under salycilic acid, 3 ij. ter. indie , 
with warm fomentations, etc. Close examination failed to dis¬ 
cern either improvement or change, until the third day, when a 
few drops of suppuration were observed between the glomes of the 
frog, almost in the middle, and directly over the posterior com¬ 
missure of the middle lacunae of the frog. A small collection had 
taken place under the frog; it was the result either of a bruise, 
on a punctured wound, or of a furuncle of that part. The lame¬ 
ness remained the same, and the general condition was without 
change. 
The animal was then brought to the hospital. The frog of the 
foot was removed, and a small punctured wound, such as might 
be made with a small wire, was found, and scarcely sufficient to 
explain the excessive lameness and the great suffering. 
For two successive days there was no change, but the same 
lameness and pain; the temperature and pulse continuing high, 
though the appetite continued pretty fair. On the 16th, the sixth 
day of the attack, no suppuration was found in the foot, but a few 
drops of synovial fluid appeared. The posterior part of the 
coronet was slightly swollen, and, on examination, gave a feeling
