The literature on High Frequency Currents is not
extensive and most of it is too technical for the average physician, who
is more interested in the application of these currents than he is in the
precise manner in which they are generated.
For this reason I have given comparatively little
space to the consideration of the various forms of apparatus, other than
to outline the types upon one or another of which all of the machines are
Further information along this line is properly
within the sphere of the various manufacturers
My intention has been to make this a practical hand-book
for the busy physician who wishes to use high frequency currents and to
learn how to do so with as little “red tape” as possible.
I have expressed my individual opinion on many points,
and sometimes this may be found at variance with that of other authors,
but it is based upon eighteen years’ practical experience involving the
daily use of High Frequency Currents and upon sixteen years’ experience
in teaching the subject.
