Diagnostic methods, chemical, bacteriological and microscopical : a text-book for students and practitioners / by Ralph W. Webster ; with 37 colored plates and 164 other illustrations.
Ralph W. Webster's 1909 clinical laboratory text, published in Philadelphia by P. Blakiston's Son & Co. for medical students and practising physicians, covering chemical, bacteriological and microscopical diagnosis. The plates are circular microscope-field views drawn in fine stipple and line — bacilli, cocci, fat globules, tissue fibres and blood cells set against flat grey or tinted grounds — giving designers ready-made roundel compositions and scattered dot-and-dash textures.
