From a roentgenologic study of the colon and appendix much valuable information can be obtained regarding these organs which could not be obtained in any other manner. In order to enhance the value of such a study, it is necessary to employ the correct technic in examining these organs and to have a clear understanding of the normal roentgenologic appearance of these organs and the variations within the normal.
This monograph, prefaced by an excellent dissertation by Dr. Antoine Bécleré, eminent French roentgenologist, clearly explains the modern methods employed in examining the colon and appendix by means of the roentgen rays. The authors explain the roentgen aspects of the anatomy and physiology of the colon and appendix. Their study of the intestinal mucosa by means of colloidal thorium dioxide injected into the bowel is most interesting. After the injection of this opaque medium the colon is examined (1) under pressure,
