W c may now refer to some special modes of shoeing, recom¬ 
mended as preventive of contracted heels, but which seem to us 
to possess inferior advantages to the preceding. We first find 
t ie unilateral shoe of Turner, which, according to that veterina¬ 
rian, relieves the foot from pressure upon the heels by placing 
the nail holes on the toe and the external branch only. Turner 
recommends also the conservation of the frog and that of the 
and 11 is Probably to this that the success he has obtained 
by that inode of shoeing is due. 
Coleman recommended a shoe very thick at the toe and thin 
at the heels, the toe being three times as thick as the heels. This 
veterinarian thought that by this shoe the animal was obliged to 
rest on his frog; at the same time the nails were driven in the 
toe principally, so as to allow the dilatation of the heels. This 
8 10 ® lms 110 re al advantages, and predisposes to corns. 
1 he bar shoe is of some utility when the frog is well devel¬ 
oped, by placing on that part the pressure of the foot, and leaving 
the heels free. But it often fails in contracted heels, because in 
applying it these parts require to be pared down, in order to in¬ 
crease the prominence of the frog, and a condition is thus pro¬ 
duced which does not exist in contracted feet. The same may be 
said of the Charlier bar shoe. Tho objections stated and the 
reasons suggested are true of all the various shoes designed to 
adjust the frog-pressure.
