The Pathogenesis and Pathology of Viral Diseases

with problems in medical physics. Even the biologist and medical man who is not directly concerned with strictly physical investigations but nevertheless depends heavily on physical instrumentation in his laboratory will find here much to his use. This is not a re-edition of the previous volume. New sections have been added and older sections have been expanded where necessary. For subjects in which little of significance has been added, references are made to title headings and page numbers in Volume I. The largest additions have of course been made in topics related to radiation and radioisotopes. Lengthy treatments, theoretical and instrumental, are given to Geiger counters, radioisotopes, roentgenography, radiation therapy, and protection and health physics. There are also notable essays on electron microscopy, optics, and spectroscopy, the physics of circulation and respiration, aviation medicine, blast injury, and decompression sickness. The list of title headings is far too long to cover in review. The arrangement is alphabetical, by title headings, with no table of contents. Authors are listed under each heading. Long subject and author indices give adequate cross-references. Bibliographies are included with each section and in general are comprehensive. Names appearing in the bibliographies are included in the author index. The text is profusely supplied with line drawings and half-tones. As the second volume is incomplete by itself, and the outlay for both is considerable ($40.00) most users will be more interested in knowing that Volume II is available on reference shelves than in purchasing it. Both are worth the price, however, to specialists in medical physics and biophysics.
