Toe clips should be very small, or dispensed with altogether. The heels: 
of the shoe should be thickened. The “Thacker” shoes are strongly recom- 
mended by some. We may here remark that large toe clips are not 
uncommonly a‘cause ofdisease of the foot, and should never be used. 
Animals subject to navicular disease, require a cool bedding on a level. 
pavement, but nothing can serve the purpose better than sawdust, or a good. 
supply of straw. Animals, asa rule, will lie down in a quiet well-bedded 
box more readily ; and, as the recumbent posture is to be encouraged at: 
night, it will be well to make the box as comfortable as possible. 
When these measures have been taken, there remain two operations- 
which have been devised for the cure of navicular disease, and of these we- 
shall say a few words. The first, frog-setoning, as represented in the second 
of our illustrations, is said to have proved serviceable in some inveterate: 
cases, when all other measures had failed. The second operation for the- 
alleviation of navicular lameness is termed neurotomy. It was at one time 
so highly thought of as to be very frequently performed. It consists in 
removing a portion of nerve from both sides of the plantar nerves of each 
fore limb. It is sometimes a very successful operation. It is, however, not 
advisable to perform it except as a last resource, when all other measures’ 
have failed, and the animal ts quite unfit for work, as, although it often 
affords temporary relief, the nerves usually grow together again after a time,. 
and the animal may become still more lame than before. In performing the 
operation, it is usual to remove about one inch from the nerve of each side of | 
both fore limbs; but sometimes it is performed on one limbonly, Neurotomy was 
supposed to have been first introduced by Mr. Sewell, but we have reason to- 
believe that the operation was practised some years earlier by Mr. Moorcroft
