ved for a time, is again as great as before. With the
other and more vital constituents of the blood-stream--namely, the
corpuscles--restoration is not so rapid. We have, in fact, a weakened state
of the system, in which it is probable it will not so successfully combat
the adverse conditions the disease may induce.
With these prefatory remarks, we may advise bleeding under certain
conditions. The quantity removed must be moderate (7 to 8 pints), and the
pulse and other conditions must show no signs of weakness or collapse.
Local bleeding, either from the toe or the coronet, is also advised. In
the former situation the sole is thinned down until a sufficient flow
is obtained, while at the coronet scarification is the method adopted.
Bleeding locally, however, is far less effectual than the jugular
operation. Neither must it be forgotten that wounds in these situations,
more particularly at the toe, are extremely liable, especially with
the existing poisoned state of the blood-current, to take on a septic
character. 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.
Other means of combating the congested state of the membrane are
principally those of local applications. With many veterinary surgeons warm
poulticing is still largely advocated and practised. We do not believe in
it. Warmth, as a means of removing local congestion, can only be successful
when applied _widely_ round the congested area, and so dilating surrounding
bloodvessels and lymphatics. Applied to the congested area itself, and to
that alone, it is almost worse than useless.
With the foot, both around and below it, a surrounding area is denied us.
The only vessels we are able to dilate with the warmth, and so enable them
to carry off the fluid from the congested foot, are those in the
limb above. That poulticing cannot be successfully there applied is
self-evident. Apart from that, it is an open question whether poultices may
not do actual harm in inducing suppuration in cases where, probably, it
would not otherwise occur.
For these reasons we hold to the opinion that when a local application is
determined on it should be a cold one. Various methods of applying cold are
in vogue. Cold swabs are perhaps most in favour. They must, however, be
_kept_ cold. When a suitable water-course, pond, or other expanse of
