| Popis: | During the process of certain experimental work now under way, it was noted that little information concerning the density of the shadows produced by the various metallic salts was available in the literature. Various workers in the study of the visualization of certain of the tracts of the human body, such as the alimentary and urinary tracts, have brought forward different selected substances, but little is mentioned of the manner in which these substances were chosen, and no evidence of an effort at standardization can be found. While it is true that certain very important and fundamental principles concerning absorbability based upon atomic number formulae have been determined recently by Hull (1) and by Richt-myer (2), nevertheless it occurred to the writer that definite efforts directed towards the tabulation and formation of a shadow scale for as many of the metallic salts as possible, would form a practical working basis for problems of investigation wherein this important factor is brought into c... |
