In the meantime I thinkit may be in the interest of medical science to placeon record the results which the further examinationof this case produced. The scales after being brought into potassiumhydroxide solution showed fairly numerous fungoidorganisms, though not so numerous as one would. too, proved unsuccessful, for the troublesome bacil-lus invariably made its appearance, even after atreatment of 30 minutes with alcohol. Therefore Imade use of the following device: I first inoculatedsixteen glucose-broth tubes with the bacillus andplaced these into the incubator. The bacillus grewvery abundantly within twelve hours. I then steri-lized these media and afterwards added a little moreglucose (to make up for any loss) and a piece ofmarble (to neutrahze any excess of acidity). Intothese media I then transplanted the scales. Thistime the bacillus had apparently exhausted themedium and no fresh growth developed. The deadbacteria sank to the bottom of the tube and thescales were clearly visible. After one week afungus started growing from two out of the sixteenscales with which I had continued these experi-ments. After fourteen days an attempt at trans-plantation to solid media failed, but after eighteendays a growth on Sabour
