We have seen very large tumorsmelt away under the action of the rays.Some ot these have been internal tumors, The Scientific Basis of Short Wave-Length Therapj the sizes of which have been estimated fn >mx-ray photographs. Just how permanentthe retrogression of the tumors max turnout to be, no one can tell at present, forthese penetrating rays have been used fora short time only. There can be no doubt,however, but that the temporary palliativeeffects in some cases are far superior to thosethat can be produced in any other way. 79 are too uncertain, or else we do not yetunderstand all of the conditions requiredto produce the different effects. Theirregularities are probablj due to a com-bination of both of these. The subjectdemands an extensive and profound seriesof investigations. The present methods of measuringx-ray intensities and wave-lengths have

Fig. 13. At present we are examining, in particu-lar, the blood changes produced by radia-tion. These changes seem to be somewhatirregular, the most regular being thechanges in the white cell count. The clinicalfindings appear also to be quite irregular.Sometimes the temperature rises, some-times it falls, and in other cases it remainsnormal. The same may be said of pulseand respiration. The great irregularity inthe effects produced by the rays suggeststhat either the methods of examination Fie. 14. far greater accuracy than those employedin the determination of the biologicaleffects produced by the rays. As is wellknown, the x-ray expert today possessesone of the most important and far-reachingmethods of diagnosis in existence. Owingto the increase in the accuracy of esti-mating dosage, he now possesses, also, amethod of treating certain types of diseasethat is not excelled in precision of measure-ment in any other branch of medicine or ON THE FUNCTION OF THE MUSCLES OF THE STOMACHSO
