Among the early printed references to X-rays in America, as well as one of the first books on the medical applications of X-ray technology. “A measure of the serious and sensational interest in the Rontgen rays can be drawn from the fact that during the single first year of the knowledge of their existence, 1896, more than a thousand books, pamphlets, and articles appeared in the public press on this subject” (Dibner, The New Rays, of Professor Rontgen, p.36). The present work is included in Dibner’s select list of 24 early publications ‘of special significance’ dealing with X-ray technology. Only three other works treating the medical aspects of X-rays are noted... William J. Morton is credited by Rutkow with producing the first dental radiographs in America, two of which are reproduced in the present work (figs. 67 & 78)." - Heirs of Hippocrates, No. 2084.4
