How to Study the Hepatics, Mosses, and Lichens with a Compound Microscope

To study any part still more in detail, place it in a drop of water or dilute glycerine between two pieces of mica or glass and view it through a compound microscope.

If it seems desirable to preserve the detail, let the glycerine mica-mount remain without a cover-glass in a place free from dust until the water has entirely evaporated, then slightly warm the slide and place a drop of warm glycerine-jelly on a mica cover and invert this over the mount.

Glycerine jelly and mica may be procured of any dealer in microscope supplies. Small bits of mica may also be procured at slight cost from wall-paper factories or from factories where mica is used in the manufacture of electrical supplies.
