The science of paleopathology has yielded much information concerning the history of disease as it affects modern man. To this new science Moodie has been a noted contributor. His present contribution, issued in a limited edition by the Field Museum, deals with observations on Peruvian mummies made largely by the roentgenologic method. To the extent that the roentgen ray is limited as an aid in diagnosis, so also are the diagnoses limited, as they concern the mummies. The book contains numerous reproductions of x-ray plates and excellent photographs of bones and of mummy wrappings. It includes not only studies of human beings but also some studies of animals. Of particular interest are the discussions of otosclerosis, mastoiditis and the relics of syphilis as they appear in these ancient bodies.
