Abstract
THE examination of thin sections of coal with the petrological microscope (see NATURE, Dec. 25, 1926, p. 913) has been extended to Tertiary coals from Baluchistan, the Punjab Salt Range, and Assam. The observations previously made on Pahæozoic coals have been confirmed by the later investigations, except for the pleochroism, which is deceptive and probably not actual.
