Show REAL DIAMONDS BUT ART1FICALLY MADE LONDON", May 3 (By Mail.) Real diamonds, artificially made, were exhibited ex-hibited in connection with the annual May lecture before the British institute insti-tute of medals. The speaker. Sir Charles A. Parsons, who is widely lepown lor his work in developing the turbine engine, told of experiments !i showed that diamonds exist in iron. The diamonds displayed were few and small, and it was stated that thoy were produced at enormous cost Only the resources of a grai engineering works made th' i xperlmenta possible However, the lecturer believed that with the advance of chemistry and electrical f-nprineerinc. it might some day be cheaper to make diamonds than dip them. A method of making diamonds of commercial size and quantity was sue gested by Sir Charles. His plan was to submit a large mass of iron, al toyed with other elements, to heat After the molten metal had 6et. but 'when fetill at a temperature perinea bo to gas. It should be subjected to I carbon monoxide at a pressure of 'about 1000 atmospheres Under this i process, ho believed, segregations I forming into diamonds might lake 1 place slowly within the mass.
