The book describes the step-by-step procedures for the preparation of organ-tissue specimen slides for microscopic examination as well as technique for producing photomicrographs all the way to oil immersion often used when the highest magnification of a biological specimen is needed for light microscopic studies. This is usually a major challenge to many scientists in the field due to paucity of published data to nearly lack of access to a comprehensive technical guide to manual methods of prepare tissue samples as needed for practical demonstrations, reviews or diagnostic purposes. Micrographs of normal sections of various organ-tissues have been included for studies, which would also help for recognition of diseased tissue micrograph whenever encountered.
