DISEASES OF THE CLAWS IN CATTLE AND SHEEP. 
Amputation may be effected either by exarticulation of the joint of 
the claw, or by resection of the os suffraginis. Harms prefers the first 
method, and lays great stress on the necessity for preserving the bulbs 
in order to ensure regeneration. The navicular bone is not removed. 
The animal is cast, firmly fixed, and an Esmarch’s bandage applied 
round the knee or fore arm to prevent bleeding. Harms then removes 
the horn in grooves at either side, and on the lower surface of the claw, 
by means of a farrier’s knife, the grooves thus made penetrating as far 
as the soft tissues and converging to one point. The coronary band is

next separated, and the pedal bone removed along with the horn of the 
claw. 
Eggeling first thins the horn over the posterior half of the outer wall 
and of the bulb. With a curved knife he makes an incision, starting 
fiom the inteidigital space, and keeping below the coronet, which exposes 
the pedal-joint, and takes the direction a to b to c (fig. 313). The 
posterior end of the pedal bone (fig. 313, c) being reached, the incision 
is continued downwards at a right angle (fig. 313, d) to prevent injuring 
the navicular bone. By pressing the toe downwards and backwards 
whilst making this incision, the pedal-joint is opened, and the inner 
wall of the claw and interdigital ligaments may be cut through. 
MdHei lepeatedly operated by this method, and recommends it. The
