Magnets as Remedy.
" Loadstone " and Magnets have for centuries been supposed
to have some influence on the human body, particularly in dis-
ease ; but it has always been in the absence of any tangible
demonstration. Professor Faraday submitted his own body to
the trial, by Dr. Keil, — who, at the time, was advocating those
views, — with most powerful and formidable permanent magnets,
but without any appreciable result. M. Pereira states, that as
early as the days of iEtius, which was in A. D. 550, it is record-
ed that this then marvellous "loadsto?ie" was bound upon the
sick part. Dr. Alfred Smee has pursued a series of experiments
for investigating this matter to some satisfactory result. He
placed the web of a frog's foot, and then the tail of a fish, under
the field of the microscope, and there exposed them to the in-
fluence of very powerful magnets, but without producing the
slightest effects upon the circulation of the blood, or upon the
capillaries. He says he has also subjected the various organs of
sensation to its influence, but never has been able to produce
the slightest effect upon the eye, ear, nose, tongue, or skin. Nor
was he more successful in his experiments on cell life, for all
these trials gave negative results. From such trials, by one so
competent, we may safely infer that terrestrial magnetism either
has no kind of influence at all over the functions of animal
life, or is so limited as to be usually an exception rather than a
rule.
jEsthesiometer.
For the purpose of aiding in the diagnosis of certain forms of
nervous diseases, Dr. Sievking constructed this little instrument,
by whom it is at length described and recommended.* Its em-
ployment is based upon the principle, that the capability of
distinguishing the distance between two points, applied exactly
and simultaneously to the skin, at different parts of the body,
