Extract

Measurements for torbernite have been given by numerous observers; the results are, however, of rather early date, and althoug the values for the ratio a:c are generally in fair agreement with the results here stated, the degree of accuracy of these measurements is not always indicated. Moreover, sevelml minor difficulties arise, add it has been suggested that some of the early descriptions refer to the allied species, zeunerite ; both species are optically uniaxial and possess almost the same axial ratios; they can, however, be distinguished by means of their refractive indices.
