The markedly pigmentedspots correspond exactly to the straps ofthe basket which the patient used tocarry. Figure 4 shows a reaction which shouldcorrespond to the administration of adose of rays of 120 to 130 percent of , in this case only 100 per cent was employed. The dorsal fieldsshow quite a marked brown ap])arent overdose was due to theapplication of a concentrated solution oflysol which the patient sometimes used towash the irradiated parts of the skin. in the cases just mentioned, the injuriousinilucnces were but slight, and therefore followed by correspondingly weak reac-tions. It follows that severe traumata ofirradiated parts of the skin may produceserious injuries. This fact readily explainsthe frequent occurrence of those startlinglat
