limbs after death, and for that purpose they were forwarded 
to me at the college. 
On inspecting the parts below the knee, a superficial survey 
at once suggested the existence of considerable and important 
lesions. The limb was generally enlarged, the hoof of 
inordinate extent, measuring seven and a half inches from 
coronet to toe. The space between the heel and fetlock was 
rounded and prominent, and to the touch hard and unyielding. 
On removing the common integument this was found to be 
much thickened, while the subcutaneous tissue was highly 
condensed and converted into a white, dense, firm, fibroid 
mass of cartilaginous hardness, so inseparably blended with 
the surrounding tissues, that their respective limits failed 
to be recognised. The flexor pedis, perforatus, and perforans 
tendons, with their investing sheath, were much enlarged and 
indurated, as were also the annular and other ligaments of 
the fetlock-joint. After examination the parts were subjected 
to maceration, and on the removal of the soft tissues the 
perforans tendon was found to be completely calcified to the 
extent of eight inches from its point of insertion into the 
plantar surface of the os pedis. The surrounding subcu¬ 
taneous tissue was similarly transformed, encasing the plantar 
vessels in a bony canal, and all being confounded with the 
altered tendon. 
The navicular bone showed the line of an old fracture 
running transversely to its long axis, and occupying its outer 
third. Reunion of the broken pieces had, however, been 
effected at the expense of considerable bony deposit, which 
had sealed them to the underlying tendon. All the connect¬ 
ing ligaments of this bone were completely calcified, and its 
under surface roughened by ossific deposit. It may be ob¬ 
served that the above described lesions were symmetrical 
in the two limbs. Both navicular bones were fractured, the 
position and direction of the fractures being the same.
