be kept in a clean condition. On no account must the animal be allowed to 
stand on bedding saturated with excreta, or with accumulation of 
decomposing matter. Stoppings for the feet must not be employed. The 
diseased portion of the frog should be removed with the knife, and the 
affected part dressed once or twice daily with about half a teaspoonful of 
powder, composed of equal parts of calomel or iodoform, or this powder may 
be alternately used with one of equal parts of starch and iodoform. A 
mixture of one part of carbolic acid and four parts of glycerine, is also a very 
valuable application. Ointment of salicylic acid will also prove of great 
efficacy. ; 
It is also well to maintain a firm pressure on the frog. In severe cases 
of: thrush, causing lameness, or when there is a tendency to grease, 
indicating a possible constitutional factorin the production of the disease ; 
it will be best to commence treatment by the administration of three or four 
-‘drachms of aloes, followed by three days’ rest, during which time the animal 
should be fed on warm water and mashes. 
FALSE QUARTER. 
By false quarter we understand the existence of one or more clefts, or 
deficiencies of horn, in any part of the wall of the foot. Referring to the 
anatomy of the horse’s foot, our readers will remember that the outer horny 
covering of the wall of the foot is secreted by the coronary substance ; and 
we may here mention that these clefts are due to destruction of this coronary 
substance by injury, such asatread. False quarter is totally different in 
nature from sandcrack. It consists actually in longitudinal flaws in the 
outer covering of the horn of the wall of the foot ; and at the bottom of the 
fissures, we find the horny laminz which are secreted by the sensitive ones. 
Although not usually causing lameness, nevertheless false quarter constitutes 
unsoundness, as it is liable to affect progression at’ almost any time, from 
injury to the thin horny covering of the affected part which is exposed. In cases 
of false quarter due to recent injury, the affected part of the coronet should 
be carefully treated. After bringing the injured surfaces together, and 
applying some antiseptic ointment, such as borax ointment, constant 
pressure should be applied by means of a bandage. 
In old cases, all that can be done is to apply a blister of red iodide of 
mercury ointment round the coronet, and to fill up the gaps with gutta 
percha, moulded in, while warm. In addition, the feet may be shod with 
bar shoes, so as to distribute the pressure more evenly. 
Not uncommonly, horses with false: quarter are passed off on the 
unwary, by thus filling up the gaps with gutta percha, and painting the hoof 
with lamp black or hoof ointment. In order, therefore, to be on one’s guard 
against such tricks, it is advisable, before examining an animal, to have his 
feet cleaned.
