To quickly assess the difficulty of the text, read a short excerpt:
E. Ubout 30 seconds. The photo-electric cell C consisted of a brass tube closed at one end by a slit about 0. 7 mm. Wide at cs and at the other end by the quartz window Q. The fluorite window F allowed the light of the de- sired wave-length from the prism to be focused sharply t c inside the exhausted glass tube V. To assist in correct focusing, the slit end o of the oell was coated with luminous zinc sulphide. The whole tube V could be rotated around a ground glass joint with a mercury s al pl...aced below it on the exhaust tube. The netal to be tested was in the form of a flat strip about 4 x 18 mm. Suspended from a brass rod sealed in glass with sealing wax passing through a mercury sealed ground glass joint above. An area about 4 x 10 mm. Was exposed to the radiation by pro- jecting through the top of the brass photo-electric oell. By ro- tating thJs strip edgewise and by the use of a lens at Q, or by sus- pending a fluorescent screen in place of the metal strip, it was possible to set very exactly on some known line of the Hg arc spectrum.
