INSTRUCTIONS

Nº. 1 Is a case for holding and protecting Nos. 2, 3 and 4.

Nº. 2 Magnifies by simply placing it on the object.

Nº. 3 Magnifies all fluids placing on the lens.

Nº. 4 Is a needle for impaling and holding insects and poisonous matter.

These are specially prepared specimens to demonstrate the power of this microscope, as they are not found in all water, vinegar, figs, prunes, cheese, etc.

IMPORTANT. The square-shaped lens (No. 3) is used only for liquids, germ life, mites, etc, in fact only where the object is so tiny it cannot be brought out clearly with the other lens. To illustrate, a drop of "Mother" of pure cider vinegar, containing life, when placed on the square lens, will show hundreds of eel-like germs swimming around. Stagnant or impure water will likewise show germ-life, but do not expect to see life in pure water, or where no life is present. This lens magnifies about 300 times. To use the square lens, place object on square end of lens, then place in brass tube, and holding to the eye, look towards the light. The round lens (No. 2) is used separately, and is used for ordinary purposes, where a good magnifying glass is necessary. The children will find this interesting and instructive in the study of botany, mineralogy, insect life, etc.
