fectly-formed wall not admitting of the insertion of nails
all around it, the shoe is held on partly by nails and partly by a strap
attached to it bound round the coronet.'[A]

3. 'This case is related by Mr. A. Rogerson, F.R.C.V.S. It occurred to an
animal regularly engaged in shunting, and happened through the corner of
the shoe becoming "trapped" between a line of metal and the wheel of
a truck. It is particularly interesting on account of the photograph
accompanying it, and which we here reproduce in Fig. 115.

'The photograph shows plainly the manner in which the holding of the
"clinches" on the left side of the hoof has resulted in drawing it off
from the foot. Had these clinches, as Mr. Rogerson suggests, been left
unfastened, then the accident in all probability would not have occurred.
The animal was destroyed.'[A]

CHAPTER IX

INFLAMMATORY AFFECTIONS OF THE KERATOGENOUS APPARATUS

A. ACUTE.

ACUTE LAMINITIS.

_Definition_.--The term 'laminitis' is used to indicate a spontaneous and
diffuse inflammation of the whole of the sensitive structures of the foot,
more particularly the sensitive laminae. Usually it occurs in the two front
feet, often in all four, and occasionally in the hind alone.

_Causes_.--In dealing with the causes of laminitis, we will first dispose
of those coming under the heading of _traumatic_. Correctly speaking,
however, lesions of the laminae thus occurring do not present the same
symptoms, nor run an identical course with the disease we now purpose
describing, and for which we would prefer to entirely reserve the term
'laminitis.' The fact, however, that traumatic causes are detailed in other
works on the same subject compels us to give them mention here.

Strictly traumatic causes giving rise to a limited inflammation of the
sensitive laminae are violent blows upon the foot, either purely accidental,
or self-inflicted by violent kicking.

A similar limited laminitis is to be found in the conditions we have
described under 'Nail-bound and Punctured Foot.' It is met with also in
the injuries resulting from tread and overreach, and in the tissue-changes
accompanying corn.

The tenderness following upon excessive hammering in the forge, or of too
long an application of the shoe in hot-fitting has also been described as
laminitis.

With either of the conditions
