Extract

It has been proved by the work ot Messrs. A. Hutchinson and A. M. Macgregor, recently published in this Magazine (1921, vol. 19, pp. 225-232) under the title 'Oil cornetite from Bwana Mkubwa, Northern Rhodesia', that the only difference—if any—between the Rhodesian mineral and the original cornetite from Katanga consists in the presence of cobalt as determined by Professor G. Cesàro in the crystals from the Étoile du Congo mine. It may be of interest to give here the results of my researches on the chemical composition of the cornetite from the Étoile du Congo mine in Katanga.
