This is a delightfully readable and valuable summary of the field of high voltage roentgen therapy. The authors call attention to the fact that high voltage roentgen therapy can be administered with a radiation that is only slightly penetrating and, inversely, that penetrating filtered radiation may be utilized in superficial radiotherapy. He defines high voltage roentgen therapy as that given by utilizing a tension of 200 kilovolts and a filtration of 1 mm. copper with a minimum effective wavelength of 0.17 angstrom unit. To deliver to an organ deeply situated a sufficient radiation to obtain therapeutic action without damaging the skin or intervening organs is the purpose of high voltage roentgen therapy, but this object cannot be truly and completely realized except by utilizing "penetrating" roentgen therapy.
