(The Bansch & Lomb Optical Co.) . Simple microscopes are very convenient when only a small mag-nification (Ch. IV) is desired, as for dissecting. Achromatic tripletsare excellent and convenient for the pocket. For use in conjunctionwith a compound microscope, the tripod magnifier (Fig. 17) is one ofthe best forms. For man5 purposes a special mechanical mounting isto be preferred. COMPOUND MICROSCOPE \ 12. A Compound Microscope.—This enables one to see an enlarged, in-verted image. It always consists of two optical parts—an objective, to produce anenlarged, inverted, real image of the object, and an ocular acting in general likea simple microscope to magnify this real image (Fig. 21). There is also usuallypresent a mirror, or both a mirror and some form of condenser or illuminator forlighting the object. The stand of the microscope consists of certain mechanicalarrangement
