rm water only, as
near blood heat as you can have it. When you have got the point of the
syringe even a very little way into the wound, you can inject a little
water, and in doing this you will probably learn more nearly where the
actual sore is to be found. The water will probably come out as fast as
you send it in, but it may not come till a good quantity has gone in.
Now, as you fill your syringe a second time with water at the same
degree of heat, you will add a single drop of strong acetic acid, or
twelve drops of white vinegar to a teacupful. You must be careful that
this is not exceeded at this stage, or you will cause great pain.
Moreover, you do no good to the sore by making the acid so strong as to
cause suffering. If it is only just so strong as to cause a comfortable
feeling of warmth, it will be all right for its curative purpose. Even
very weak acid combines with the irritating waste matter that is
keeping the sore diseased, and produces the desired healing effect. You
have only to add one drop after another of the acid to your full
teacupful of warm water, till the feeling produced by the syringing is
all that could be desired. In the case of the limb that we refer to, a
sensible mother used the syringe and the acid so skilfully as to heal
the internal sore in a very short time, and thus the external wound
quickly disappeared. Of course, if the wound is so very deep that the
acid cannot be got up to cleanse it thoroughly, surgical aid should be
sought.

It may be well, however, to take another case or two for further
illustration. Here, then, is a decayed tooth extracted, but the part
from which it is taken does not heal, as is usual. The hole in the gum
does not close, and a discharge of offensive humour flows from it
constantly. The bone of the upper jaw is evidently wasting, and the
decay has extended somehow considerably up the side of the nose. The
hole, however, is so small, that the usual glass syringe cannot enter
it. We got an exceedingly small instrument, used for the injection of
morphia under the skin. The point of this syringe is a needle with a
point that is hollow nearly to the very end. When this point was broken
off, the hollow part was so small that it entered the hole in the gum,
and so it was easy to inject the weak acid up to the bottom of the
sore, which had come to be only a little under the eye. About an inch
and a half of hollow had to be washed out with the acid. But in a very
s
