pecially in the tubes. We can, therefore, look forward to greater achievements in the treatment of malignant and other diseases by the x-ray.

I believe as a therapeutic agent the new radiation is in its infancy. Much will develop as the technic of application is perfected. The improvement in apparatus is well illustrated in the progress that has been made in radiographic work. In

1896 I made fair radiograms of the adult hip in from fifteen to thirty minutes; to-day, the time of exposure has been so reduced that I recently made a good radiograph of an adult hip in one minute and thirty seconds. With greater experience results have been obtained that border upon the miraculous. In certain cases under observation where surgical intervention

was out of the question-not to be considered, the x-rays have been applied empirically and these small cases have been not only benefitted but cured. The illustrations presented show fairly well the changes wrought by the x rays in several types of cases in which this treatment was carried out.

The Figs. 1, 2, 3 and 4, of the case of cancer, both breasts, a so called cancer en cuirasse, illustrates what was accom

plished in a seemingly hopeless case. A large painful ulcer, foul-smelling and bathed in bloody ichorous pus, was present. The ulcer was about eight inches long and five inches wide. The anterior wall of the thorax was studded with typical cancer nodules. After thirty-three x-ray exposures the ulcer is now practically healed, all the nodules having disappeared. A

small spot, less than the size of a dime, now remains at the site of ulceration. There has been complete relief from pain and marked improvement in this patient's health.

The Figs. 5, 6, 7 and 8, the case referred to me by Dr. Gettys, show the transitional stages developed in an infiltrating carcinoma of the cheek and inferior maxilla that was not con

sidered favorable for operation. In fact, a surgical operation if performed, would have been a surgical exercise.

The Figs. 9 and 10, of the case of rodent ulcer is of interest. This patient was irradiated eleven times at intervals of three and four days, then ceased his visits as a dermatitis set in With the resuddenly, accompanied with severe headache.
