This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1901 Excerpt: ...well as glass plates." Since the time when this paper was published, X ray workers have tried well nigh every brand of film and plate on the market, whilst makers have experimented with special emulsions. No very startling improvement has been made in the preparation of plates, and the general concensus of opinion seems to be that any good brand of very fast plate gives excellent results. At one time there were statements abroad that a slow plate was as rapid under X rays as a quick one, but this is a fallacy. I have used many brands, but have always found those which are fast for ordinary light are fast for X rays. Isochromatic plates I have always found very slow. This statement must be taken as merely relative and not quantitative. It may be that the plate speeds of widely differing brands are nearer together for X rays than for light, but I have come across no exact experiments on the subject. Perhaps the favourite plates are the Cadet lightening, the Paget xxxxx, and the Lumiere plates. I give personal preference to the Imperial flashlight plates. The best advice, however, to any one who wishes to take up radiography, and who is already a photographer, is to use those plates which he understands. One of the difficulties in development is to obtain density. Radiograms are apt to be thin and lacking in contrast. To overcome this difficulty, and at the same time to decrease the time of exposure, special plates and films have been made coated on both sides. The rays after having done their work on the first coat pass on with very slight diminution and produce a fresh image in the second one; if the plate be thin there isf no practical difference between these images which are of course in perfect register. Such plates are a little awkward to develop b...
