Extract

IN the course of an investigation into the distribution of millerite by Dr. F. J. North and the writer, the presence of linnaeite (sulphide of cobalt Co3S4) in the clay-ironstone nodules of the Coal-measures of East Glamorgan was confirmed. That sulphide of cobalt should accompany sulphide of nickel is not surprising, but the only record of its occurrence in Wales so far as the writer is aware, takes the form of a note (without title) by A. L. des Cloizeaux in a French publication. This record was based on a specimen from the “Rhonda” (Rhondda) discovered by a Mr. Terrill, of Swansea, which does not seem to have been preserved. It is possible, too, that the mineral may occur in the Coal-measures of Belgium, as nickel and cobalt were detected in the soot from flues under which coal from Beyne (near Liége, Belgium) had been burned.
