RUPTURE OF PERFORATUS TENDON AND FIBRO-CARTILAGINOUS 
LIGAMENT AT ITS INSERTION ON THE “ OS-CORONA.” 
By L. T. Bell, D.V.S. 
On October 10th, about 19 p.m., a bay gelding nine years old, 
and about 15.3 hands high, was led into my place of business 
acutely lame in the near or left forward extremity—the property 
of Mr. Darling, of Jamaica, Long Island. 
History of case, (as related by driver):—The animal had 
been lame, unable to work, two weeks previous to present lame¬ 
ness, and laid up for rest, which rest had brought about sufficient 
improvement to warrant him to again resume his work. The 
horse started with more or less lameness present, and continued 
to get lamer until within half a mile of my office, when he re¬

was unable to place the foot to the ground, hence he was brought 
to my place and put up for the night. 
I did not see him that night, as I was at that time acutely 
lame from a sprained ankle. I saw him the following morning. 
He was suffering acutely, and unable to put the foot to the ground. 
I immediately had the shoe removed and the foot examined, 
but found nothing to account for the lameness ; but just above 
the hoof I discovered swelling, heat, pain, and unusual motion of 
the bones, but without crepitus. All the motions of the foot, or 
digital region, were perfect, except that of extension, which was 
in excess. From the symptoms present, and history of the case, 
I was satisfied of the presence of navicular arthritis, and diag¬ 
nosed the present trouble to be fracture of the navicular bone. As 
I had never seen a case of this nature, and considering it an in¬ 
teresting case, I called in my friend McLean, who first thought 
it a case of rupture of the suspensory ligament at its insertion ; 
but afterwards rather concurred in my opinion. On the 12tli, 
my friend Holcombe called. I immediately seised the opportu-
