Professor A. W. Wright and Mr. H. A. Bumstead have made applications of the principles of solid-photography, recently discovered by Professor Rontgen, of Wurgburgh, with decided success. Experiments with cathode rays have been made upon various small animals and different opaque substances, and very definite negatives have been obtained. These investigations will be continued...
...only a short time ago that the remarkable discovery was made by Professor Rontgen of Wurzburg of a means of obtaining on a photographic plate, images of objects covered by wood or other material impervious to rays of light. It must therefore be a matter of great interest to the University to learn of the experiments now being carried on in the same line, and it would seem with much success, by Professor Trowbridge in the Physical Laboratory. An account of the experiments is given in another column. It is interesting to note how quickly the attention and study...
