Abstract
IT would be difficult to over-estimate the value of the contributions to our knowledge of rocks and rock-forming minerals that have resulted from the adaptation of the microscope to petrographical research. The technique of rock examination with the polarising microscope, evolved since the pioneer work of H. C. Sorby, has long been so effective as to make the instrument indispensable to the petrographer.
