This was the second attempt made by Professor Trowbridge to obtain the desired effect with a Crooke's tube. The first attempt, made a few minutes before, was partly successful. The ordinary sixty-volt alternating current used for lighting the building was sent through the primary of an ordinary coil. The resistance of the primary of this coil is one-tenth of an ohm, and of the secondary 6000 ohms. The current through the primary was not stronger than 15 ampheres. The current from the secondary of the first coil was sent through the primary of 25 turns...

The fluorescent effects were less sharply localized than usual. From the ease with which the photographic effect was obtained, it appears doubtful whether so complicated and powerful electrical apparatus was really necessary. It happened to be at hand and was therefore used. It is evident that the impression obtained on the plate is rather a print than a negative...
