Measureable crystals of the mineral löllingite have been so rarely found that a new occurrence seems worthy of record. The observations here presented are based on specimens found during 1926 in the orebody of the mine at Franklin in a drift of the 750 foot level north. The crystals are sparsely embedded in a white limestone of medium grain together with grains of a gray pyroxene and occasional dots of franklinite. The löllingite crystals are complete individuals, brilliant tin-white in color, ranging in size from tiniest specks to a diameter of 3 mm. They break freely and cleanly from the matrix and the brilliance of their lustre marked them at once as suitable for crystallographic study. Several crystals were measured by the junior author and gave excellent readings and very accordant angles as recorded in table 1 below.
