Roentgen energy. Many devices have been offered, butall of them are subject to much error, either from the per-sonal equation of the operation, or on account of inherentphysical properties in the makeup of the apparatus itselfwhich lead to variations in their readings; some of thesensitive substances used are subject to change from othercauses than Roentgen ray action; the result with otherswill vary with atmospheric conditions of moisture or. elec-tricity ; it seems that experience in the use of the rays willenable the expert to judge as to the effect he is going toproduce when he knows the type of machine he is using,the amount of primary current supplied, the kind of inter-rupter, and the condition of the tube. Of course, aRoentgenmeter which is free from the defects above men-tioned is greatly to be desired; it would be a great satisfac-tion to the expert operator and would make Roentgentherapy much safer in the hands of the general practitionerwho has only infrequent use for it.
