Histological Technique

Histological Technique by Benjamin Freeman Kingsbury is a foundational manual of practical methods for preparing and examining tissues with the light microscope. The work outlines the aims of fixation, isolation, sectioning, staining, and mounting, stressing that fixation should preserve structure as in life while enabling reliable identification of chemical and physical components. It surveys a broad set of fixatives (osmium tetroxid, platinic chloride, picric acid, acetic, chromic and mercuric salts, alcohols, formaldehyde, nitric acid) and the strategies for penetration and washing to minimize distortion. The book then treats isolation of tissue elements and dissociation, including maceration and physiological media, before describing sectioning with or without embedding, and the three embedding methods: paraffin, celloidin, and freezing. The staining unit covers in toto and section staining and progressive/regressive methods, with major stains (hematoxylin, carmine, safranin, eosin, gentian violet, orange G, Congo red) and special methods (Weigert, Ehrlich–Biondi–Heidenhain, Mallory’s, Benda). It continues with connective tissue, muscle, nervous system, blood, and histochemical techniques, plus mounting, labeling, and storage advice. The volume emphasizes careful technique and rational choices to reveal structure and function.
