PURE SCIENCE AT WEMBLEY.

';;•''■ C«oic ov* own cwMSPorowrt.) LONDON, April 8. v \ The Royal Society's' exMbit.of Pure Science in the British Goternment Pavilion at' Wembley haaj been designed .to provide '. instruction for the etudenta of science in all parte of:the Empire, and to make the various branches of the developments of modern discovery; at once intelligible and entertaining to' the general public. Opportunity will thus be afforded to study the processes nnd the results of the work of the greatest menTbf science in the world. •In scientific enterprise . Great, Britain has been, and remains, supreme; The exhibit, covering every .aspect of modern science, will be the 'most interesting and instructive of its kind yet displayed. Arranged by: the itoyal Chemical Committee, it will illustrate by actual demonstration some of * the niost recent discoveries in pure science, the processes by which the discoveries Were made, and their application' to'■; various utilitarian purposes, such as the employment of Thermionic valve as an amplifier of wireless waves, how the eilect of ultra-violet light on the discharge of electricity froin an insulated' conductor can be used in the photometry of the stars, and how positive rays are applied to the analysis of chemical elements. ■ In the exhibition are provided demonstration benches, fully equipped with iipparatus and the- methods by which men of science have discovered some particular new InW or principle. The discovery of the electron will, bo illustrated by the experiments first conducted bv Sir' William . Crookes, and continued by Sir J. J. Thomson. In Thcrmlonics, tho. work of Gutjhrie, 0. W. ilichardson, and Fleming, will be illustrated: together.with the researches of Sir E. Rutherford and his pupils on atomic structure, and C. T. R. Wilson's beautiful experiments. The foscinatinc subject of radiation nnd wave motion in the,ether will bo illuminated liv showing N tlie methods bv which tlie long series'of ether Waves are measured. The science of accurate measurement will be exemplified in the displav of measuring instruments from the ultramicroscope up. to those used ,nt' the National Physical Laboratory In measuring gauges to the millionth of an inch.
