Das Mikroskop und seine Anwendung / Ein Leitfaden bei mikroskopischen Untersuchungen

A practical guide to the compound dioptric microscope that explains essential optical principles (lenses, focal length, magnification, aberrations) and describes instrument parts, adjustments, and illumination methods including condenser, diaphragms, immersion, and micrometry. It gives advice on purchasing, centering, cleaning, and routine maintenance, then presents slide preparation, mounting techniques, preservatives, and mounting devices. Illustrated practical examinations survey a wide range of specimens and routine analyses—foodstuffs and adulterants, spices and starches, fungi and diatoms, blood elements and other tissues, parasites such as trichinae, hairs and fibers—aiming to equip users for inspection and everyday microscopic work.
