r from the foot of one animal to that of
another, undo the good that the warmth of the poultice is bringing about.
The advantage of the ordinary sacking or canvas is that it may be cast
aside after the application of each poultice. Where the boot is kept clean,
however, it will save a great deal of time and trouble to the attendant.
While on the subject of poulticing, it is well to remark that in many cases
it may be more advantageous to supply the necessary warmth and moisture to
the foot by keeping it immersed in a narrow tub of water maintained at the
required temperature. By this means the warmth is carried further up the
limb (sometimes an important point), and the water can more conveniently be
medicated with whatever is required than can the poultice. In fact, it is
the author's general practice, where the attendants can be induced to take
the necessary pains, to always advise this latter method.

Where a dressing is relied upon by some practitioners on account of the
warmth it gives, others, even in identical cases, will depend upon the
effects of cold. This may be applied by means of what are called 'swabs.'
In their simplest form swabs may consist only of hay-bands or several
layers of thick bandage bound round the foot and coronet, and kept cool by
having water constantly poured upon them. In many cases the form of swab
depicted in Fig. 54 will be found more convenient.
When only one foot is required to be dressed, and a water-supply is
available, by far the preferable method is to attach one end of a length
of rubber tubing to the water-tap, and fasten the other just above the
coronet, allowing the water to trickle slowly over the foot. In cases where
a forced water-supply is unobtainable, and the case warrants the extra
trouble, much may be done with a medium-sized cask of water placed
somewhere over the animal, and the rubber tubing connected with that.
Where the dressing is desired to be kept applied to the sole and frog only,
there is no method more satisfactory than the shoe with plates.

The plates are of metal, preferably of thin sheet iron or zinc, and are
slipped between the upper surface of the shoe and the foot after the manner
shown in Fig. 55. The plates th
