Excerpt from Radium, X Rays and the Living Cell: With Physical Introduction Our object in the present book is to describe some of the main experimental facts which have been established, as to the effects that the X rays and the rays from radium have upon having cells. In order to make the subject generally intelligible, a description of the properties of these radiations was necessary, and Part I. is designed, not only to provide information in this respect, but to meet the needs of those who approach the subject with a view to experimental investigation. A large amount of interest centres around the action which the rays have upon malignant cells, and some of the most detailed studies have been made by investigators in this connection. The results which have so far been reached are, we ma venture to hope, a good augury for the foundations of a rational basis of radio-therapy. This, however, is but one aspect of the effect of the rays upon the living cell, and we believe that an increased knowledge of the reactions exhibited by normal healthy cells and tissues is necessary before the real nature of the processes set up by these rays is revealed. The subject is not approached from the clinical aspect, but data have frequently been selected from the details of clinical observations, when these have borne upon the subject-matter in question.
