Sinopsis

Excerpt from Use and Care of the Microscope: Extracts From Manipulation of the Microscope

How to Set Up the Instrument. Draw the instrument from the case by grasping the base and pillar; free from dust with a large camel's hair brush, 1 inch or 1 1-2 inch, or by wiping carefully with Chamois skin, or old linen. Place the instrument on the work table, which should be of such height that observations can be made with the utmost possible comfort without straining the neck, or compressing the chest. Bear in mind always to sit as upright as possible.

If the instrument is used in the upright position, place the base close to the edge of the table; if inclined, it may set farther in. Rest the arms, as much as the height of the instrument will permit, upon the table.
