page 227 note 1 It seems hardly necessary to give additional evidence of the distinctness of these two pyroxenes. I may mention, however, that I have recently mounted a specimen of the monoclinic mineral, so that I can rotate it round the c-axis under the microscope. It is green in colour, and does not show a trace of pleochroism in any position.
