LAMENESS IN HORSES.

copeia, and the medical almost as well. Alum, nitre, calomel, 
chloride of lime, the oxydes and sulphates of zinc, iron, copper, 
verdigris, sulphuric and nitric acids, hydrochloride of antimony, 
the spirituous tinctures, tar, &c., have all been called into requi- 
sition. Not that above one-tenth of them are really required ; 
though frushes in general, like troublesome old ulcers, often do 
best under change and variety of dressing. A very old unguent, 
and I think — and I believe I shall be supported in my opinion — 
a very useful and efficacious dressing for frushes, and one of 
general application, is the following : — 
Take of Verdigris *iss 
Alum Jss 
Vinegar Jss 
Treacle %iv 
The first two ingredients being separately powdered and subse- 
quently mixed together, the vinegar is to be poured upon them, 
and afterwards the treacle, and the whole well stirred and incor- 
porated. The mixture is then to be simmered over a dull fire 
or in a water-bath, and kept constantly stirred the while it is 
simmering. 
For ordinary frush, some simple dressing, or this ointment — 
which is emphatically called f rush ointment — will suffice. The 
latter is likewise an excellent resource after we have done the 
required execution with the escharotic applications. The grand 
considerations in the treatment of frush, after all, however, are, 
as I stated before, to look to the restoration of the functions of 
the frog, and to take special care to guard it from wet and dirt ; 
since there are no greater enemies than these to the healing and 
well-doing of all diseases of the secretory tissues of the foot. 
And these precautions are not only necessary during treatment, 
but become requisite to be continued for some time after cure, in 
order to ward off relapse : for relapse, in the case of long- 
standing and habitual frush, is but too likely to happen. Nor 
does any measure w r e can put in practice more completely and 
wholesomely effect the principal of these objects, viz. the return 
of healthy action to the frog, any thing like to the same degree 
as the shoeing with tips. It is really quite surprising what a 
salutary metamorphosis the contracted and frushed foot, or the 
foot that has been frushed, in a few months undergoes under 
the operation of tips. It no longer remains like the same foot ; 
neither does it any longer possess the same liability to become 
disordered*. 
* It may be useful here to remark, that the preferable mode of apply- 
ing gutta percha as a substitute for leathern sole, is, by way of prepaia- 
tive, to warm the hoof first in hot water, and then to stick the softened 
gutta percha to the sole and frog by means of the “ solution of gutta percha.” 
The surfaces intended to adhere must previously be wiped quite dry.
