Many doctors will doubt the efficacy of the percentages of salicylic acid,
thymol iodide, menthol, oil of eucalyptus, and its vehicle purified naph=
thol. These percentages were worked out for each ingredient after much
deliberation regarding compatibility, corrosive action, nebulization,
mechanical irritation to skin, oder of solution, and the psychological

appeal to the user by cooling effect to the feet.

Generally the true percentage of athlete’s foot is not revealed by the
doctors or authorities in their respective districts, The faot that this
has remained an wnreportable disease probably accounts for the reason

that true statistics are not avaiable.

It is easier to prevent a disease than it is to cure after pathological
disturbances have taken place. Let me state here that my interest was
created after having many complaints from the student body of the college
which I serve as examining physician. Many types of treatment had been
employed, a few being potassium permanganate baths, various ointments and
liquids containing combinations of salicylic acid, resoroinol, boric acid,
tincture merthiolate, thymol iodide, oil of wormwood, tincture of benzoin,
trichophytin, vaccine by Arlington, coal tar derivatives, ultra-violet
light, powders of various types, fractional x-ray, and even various phar~
maceutic ointments. These are the common methods employed by doctors to
whom these students were referred for treatment.

In closing, may I state that the inventor of this machine has made many pro-
gressive changes as a result of the research and tests conducted by this in-
vestigation. This method of prophylaxis has not been placed commercially
before the public. His earnest endeavor is to win the approval of the
