After the experiment was finished Professor Trowbridge explained that the same light can be produced with a common electric machine, but the plate must be exposed an hour when this machine is used. This shows how simple the process really is. The chief advantage of the large apparatus is that when it is used only a minute's exposure is necessary. The distinguishing character of the cathode rays is that they do not go between the two poles. They can be thrown any way. For instance, a small piece of aluminum can be used to throw them in any direction...
...there is no central opaque partition. The hand or object to be photographed is put on the slide and you get a photograph of the shade. As glass absorbs the rays a lens would be of no use and would prevent the taking of a photograph. Thus the common process of photographing is exactly reversed with the cathode rays. This was illustrated by a picture thrown on the screen where a camera was shown with the larger end towards the cathode and the lens pointed away uselessly...
Doubtless the rays exist in common electric lights and in sunlight, but as yet scientists have proved their existence only in a vessel such as Crooke's tube. With these invisible rays photographs can be taken at any time, even in the sunlight. In connection with the cathode photographs it is interesting to note the length of exposure that has been necessary to take photographs at different periods. The table is as follows...
...give men an opportunity to meet who otherwise would not do so.- (x) Men who live at a distance from the yard could meet there.- (y) Many men who at present feel that they would be benefited by acquaintance with men of different stamp and who now have no common ground upon which to meet would find one there.- (4) It would give a centre to college life.- (x) It would supply a meeting place for graduates.- (y) It would supply a point towards which students would gravitate for information and in leisure moments for recreation.- (e) It would increase...
