FAULTY CONFORMATION 157 
owner that, by reason of the length projecting, the shoe is 
liable to be torn off. 
Should the ‘knuckling over’ have become complicated 
by bony deposits round the seat of the original injury, then 
a favourable modification of the condition is not so likely 
to result. 
The benefit to be derived from the shoe with an extended 
toe-piece in a case of excessive knuckling is admirably 
shown in a brief report of a case, under the title of ‘ Hooked 
Foot,’ in vol. xiv. of the Veterinary Record, p- 716: 
‘An eighteen months’ old filly showed a deformity of the 
third phalanx, resulting in her walking with the front face 
of the hoof on the ground. The flexors were apparently all 
right, and the bending back seemed to be due to contraction 
of the ligaments of the joint and the sheath of the 
perforans. 
‘On the ground of absence of contraction of the flexors, or 
atrophy and paralysis of the extensors, the surgeon con- 
sidered the lesion curable by simple orthopedic measures. 
By means of an elongated toe-piece to the shoe and calkins, 
which were shortened every fifteen days, the filly was com- 
pletely cured in seventy days.’ 
H. THE CROOKED FOOT.

Definition.—The foot thus affected has one side of the 
wall higher than the other. 
Symptoms.—This deformity is the better recognised when 
the foot on the floor is viewed from behind. In addition to 
the difference between the height of the inner and outer heel 
is seen at once a deviation in the normal direction of the 
horn. That of the higher side is distinctly more upright 
than that of the lower, and runs from above downwards 
and inwards towards the axis of the foot, while the horn of 
the lower side maintains its normal direction of downwards 
and outwards.
