In normal brightfield illumination a completely transparent specimen is very difficult to observe in detail because all areas of the specimen are equally dense. Darkfield illumination displays border effects in completely transparent specimens due to edge ...
A Simple Method for Phase-Contrast Microscopy BY 1 D. A. KEMPSON, 0. L. THOMAS, AND JOHN R. BAKER {From tlie Department of Zoology and Comparative Anatomy, Oxford) HE method described in this paper enables anyone to use phase- contrast microscopy without waiting to obtain special objectives or T condensers. The phase-contrast method is particularly valuable in the examination of living cells with high powers. The most perfect lenses for studying living cells in body-fluids or saline solutions are water-immersion lenses ...
