Necrosis and consequent sloughing of the skin is bound to follow, and an extensive ulcerous wound, or a spreading suppuration of the coronary cushion is the result.

a, Cavity in the horn of the wall; b, enlargement of the coronet and the horn of the wall following subcoronary suppuration; c, cavity in the wall following purulent inflammation of the sensitive laminæ; d, hollow in the horn of the sole consequent upon suppuration of the sensitive sole.] (c) Necrosis of the Extensor Pedis.

As a result suppuration ensues, and the animal is lame.

Seeing, however, that suppuration, if once set up, would add further to the intense pain the animal is already suffering, and considering the always constant exposure of the foot to infection, it is perhaps wise to persist in daily changing of the dressings.

(c) Suppuration.

Should the animal survive the pain and exhausting calls made upon his system by the accompanying fever of the foregoing conditions, the case ends either in resolution or suppuration.

What might possibly have remained a comparatively simple inflammation is induced by the operation itself to terminate in the more complicated and serious condition of suppuration.

Instead, the tissues around, aided by a process of suppuration, cast the offending portion off as a slough.

By its means the process of suppuration is aided, and the swelling (at first tense and hard) either becomes gradually softened, its contents discharged, and a simple abscess cavity left behind, or the suppuration runs immediately round the necrosed structures, and casts them off bodily as a slough.

When the condition has gone undiscovered until commencing necrosis and suppuration are plainly discernible, then the wisest course we can follow is to do all we can to hasten removal of the necrosed portion.

Even when pointing is not very evident, and suppuration is plainly more or less diffuse, benefit may still be derived from the use of the knife.

Either from a violent blow upon the hoof, or from the animal himself kicking violently against a wall, death of a portion of the sensitive structures takes place within the hoof, suppuration ensues, and the formation of quittor commences.

Any other diseased condition of the foot in which suppuration is present may in like manner terminate in quittor.

It may so happen, however, that we first see the case when the symptoms are wholly those arising from a painful suppuration within the horny box.

Either from violent blows upon the hoof, puncture from below, from corn or from sand-crack, or any other causes we have enumerated, suppuration is occurring deeply within the hoof, with as yet no opening upon the coronet.

Even when an opening has already occurred on the coronet, the same condition of sub-horny suppuration may be met with in cases when the opening of the fistula has by some means or other become occluded.

The effect of the injection during the first eight or ten days is to render suppuration more abundant and whiter.

This, however, when the suppuration is abundant, cannot commonly occur, as the bloodvessels within the bonethose of the medullacommence to supply blood to the affected part.

Here we have three bones whose medullary cavity is extremely smallalmost nil, in factwhich explains in some measure how easy it is when suppuration exists to get necrosis and exfoliation of, say, portions of the os pedis.

On the other hand, it may end in suppuration or may become chronic.

At the end of a week sufficient horn was removed to ascertain the cause of the constant suppuration.

In unfavourable cases, and these unfortunately are only too common, the condition terminates in suppuration.

We ourselves, too, have seen two cases where suppuration of the pedal articulation occurred in the septic pyæmia of foals, a disease known commonly as 'joint-ill,' and characterized by an infected state of the circulation.

The penetrating object is nearly always dirtybacterially dirty, at any rateand suppuration only too readily commences.
