Abstract

SEVERAL very ingenious methods for facilitating the microscopic examination of the structure of plant fossils have been recently described and illustrated in NATURE. No mention, so far as I have noted, has been made of that by which the smoothed surface of a fossiliferous rock is examined by reflected light, as may be done with the ultropak microscope. In this instrument, as many will know, the light is introduced laterally into the body of the microscope, reflected downwards by an annular mirror and brought to a focus by an annular condenser in front of the objective.
