Extract
A Specimen in the University Museum consists of black tetrahedral blende, exhibiting perfect metallic lustre; indeed, the brilliant steely cleavage surfaces of the mineral and its metallic tarnish raised a doubt whether it could really be blende; but in very thin fragments viewed by transmitted light it is seen to be brown in colour.
