THE NEW PHOTOGRAPHY. The [highly rarefied Crookes' tubes used for pro- ducing the mysterious X rays are at a premium, and it is hopeless for enthusiastic scientists to attempt to make them with the ordinary air pumo, the valves of which do not sufficiently check the rush back of air when the vacuum is becoming at all complete. A Ciookes radiant matter tulis contains somewhere about a millioneth of an atmosphere. Big induction coils, used for transforming the electrical current into the requisite high tension, are also difficult to pro- cure. Mr. J. W. Gifford, in his lecture at Bristol the other day, said he was almost overwhelmed with applications from people who desired their bones photographed so that the disease supposed to be there might be made apparent. Unable to dissociate their ideas from the ordinary photographic methods, some hid assured him that their rooms were admir- ably lighted, and one added that there was a capital sea view for a background.
