Show ject of the crystallization of carbon by the well-known electro-chemist, Dr. Borchers, who contributes an article to "The Zeitschrift fur Elcktrochemie" reviewing the past attempts in this di-ments. di-ments. Moissan worked upon the line of crystallization of fused carbon under un-der immense pressure, while Eorchcrs r. ttnins the same or similar results by maintaining n carbon rod at the high 1 "rnperaturo of the electric furr.ace for 'nsiderable time, the surface of the rod showing distinct evidences of crystallization. crystal-lization. The experiments have been carried out upon a small scale only, and, being unable to continue the researches, Dr. Borchers gives a full account of his method and apparatus, trusting that further investigations nay be carried on b- those who have powerful currents at their disposal and opportunity to carry out all the conditions which success suc-cess demands. TRYING TO MAKE DIAMONDS. JYo Great Success Has as Yet Been Attained. The experiments of Moissan and his success in producing microscopic crystals crys-tals of carbon, which, technically at least, were entitled to be called artificial arti-ficial diamonds, are well known.
