substance may, however, also commence
from without. A report on this condition, under the title of 'External
Seedy-Toe,' is to be found in vol. xxix. of the _Veterinary Journal_, from
which we borrow Figs. 130 and 131.

In Fig. 130 it will be seen that the disease commences at the plantar
surface of the toe, and extends upwards and inwards. The same condition
may also appear anywhere between the coronet and the ground, gradually
extending into the substance of the wall, as shown in Fig. 131. According
to the writer, Colonel Nunn, the progress of the disease in this latter
case appears to be faster in a downward than in an upward direction. This,
however, is more apparent than real, as the rate of growth of the horn
downwards detracts from the progress of the disease upwards, although it
spreads over the horn at the same rate.

Before concluding the symptoms, we may again allude to the fact that,
although usually occurring at the toe, the same condition may be met with
in other positions--namely, at either of the quarters. In appearance and in
other respects it is identical with that occurring at the toe.

When the animal is lame and the existence of seedy-toe is surmised, or when
the cause of the lameness is altogether obscure, a little information may
perhaps be gathered from noting the wear of the shoe. If the animal has
been going lame for any length of time as a result of disease in the
sensitive laminae, then the shoe will be greatly thinned at the heels, and
the toe but little worn.

_Treatment_.--As with diseased structures elsewhere, the most rational
treatment, when possible, is that of excision. The entire portion of the
wall forming the anterior boundary of the cavity is thinned down with
the rasp and afterwards removed with the knife, wholly exposing the
hypertrophied, but usually soft layer of horn covering the sensitive
structures. These hypertrophied portions are also removed, and every
particle of the dust-like detritus cleaned away. After-treatment consists
in dressing the parts with a good hoof ointment, protecting them, if
necessary, with a pad of tow and a stout bandage. It may be that the
removal of a large portion of the wall may for some time throw the animal
out of work. Acting on Colonel Fred Smith's suggestion, this may be avoided
by having made a thin plate of sheet-iron, slightly larger in circumference
than the portion of horn removed, and shaped to follow the contour of the
foot. This m
