progression becomes shuffling, if both fore feet are affected. The heels are 
put to the ground first, but not so markedly as in laminitis. From the latter 
disease, villitis may be distinguished by the swollen condition of the coronet, 
and the harsh, dry, and striped condition of the horny crust. In these cases, 
which it may be mentioned are generally due to work on hard stony ground, 
the shoe should be removed, and bar shoes applied. Rest is essential. A 
mild aperient such as three or four drachms of aloes should be administered, 
and the diet should consist for three days of bran mashes and warm water. 
During this time, poultices should be assiduously applied ; but afterwards 
cold applications to the coronet may take their place for a time. When the 
inflammation has subsided, a mild blistering ointment made of three parts of 
lard, and one of ointment of red iodide of mercury may be applied around 
the coronet. 
CARBUNCLE OF THE CORONARY BAND. 
THE second disease of the coronet of which we may say a few words is a 
very rare one. It is termed carbuncle of the coronary band, and has 
‘fortunately only come under our notice on two occasions. These cases are 
always of great danger. It is our practice to administer a fair dose of aloes 
in the first instance, and to remove the shoe in order to make a careful 
examination of the foot. Internally, drenches composed of two drachms of 
carbonate of ammonium, and half an ounce to an ounce of tincture of opium 
may be given three or four times daily. The animal should be fed on 
oatmeal and linseed gruel, or indeed with almost anything he will take, to keep 
his strength up. Locally, the sloughing ulcers should be powdered well over 
with pulverised nitrate of lead, or equal parts of iodoform and calomel. 
‘Professor Williams recommends nitrate of silver. Above all things the 
stable should be thoroughly cleansed, and all the hygienic conditions 
attended to. 
HORN TUMOURS. 
We have now to speak of horn tumours or keratomata, which are 
formations situated at the inner side of the horn of the hoof of the toe, and 
caused by pressure of the toe clips, or by blows. These horn tumours, usually 
seen at the toe of the hind feet, but not uncommonly met with in the fore 
ones, in many instances cause unmistakeable lameness. They press on the 
pedal or coffin bone, and thus cause a corresponding gap in its substance. 
We have not encountered many of these formations of late; for it has been 
found quite possible to discard the use of toe clips altogether as unnecessary. 
Moreovor, when still used, they are often made of less size, and are not 
hammered down with the violence which smiths were wont to deem it their duty 
to employ. Horn tumours constitute unsoundness, as, unless the coffin bone 
becomes absorbed, in correspondence with the growth of the tumour, 
lameness is manifested.
