CAUTION: The blade of the micro- slicer is very sharp. Handle the micro-slicer with care.

the waste cup. Using the eyedropper, touch the slide just above the specimen area and slowly let the water drain into the cup.

With a paper towel, pat the underside of slide dry. Be very careful and try not to touch the specimen. Allow the specimen to air dry for sev- eral minutes.

Some of the specimen will be flushed away, but enough will remain on the slide to make good observations. To save your slides, follow the pro- cedure described previously.

The Micro-Slicer

Insert specimens you wish to study into the holes of the micro-slicer (O, Fig. 1). Rotate the knob to cut your specimen into thin slices. The Micro- slicer is an ideal tool in the making of section slides.

A Simple Section Slide

Section slides are extremely thin slices of tissues of skin, leaves, flower stems, and other materi- als. Generally, section slides are very difficult to make without special equipment and proce- dures. However, there is one common house- hold item which can be sectioned without special equipment: the common onion, made up of lay- ers of tissue.

Peel off the very thinnest layer you can. One that is nearly transparent will make an ideal section. Slice into a piece about 1/4 x 1/4 inch.

Put two drops of eosin (F, Fig. 1) in a bottle cap. Pick up the piece of onion with your tweezers (A, Fig. 1) and place it in the bottle cap.

Wait for a minute or two. Using the tweezers, remove the piece from the stain. Hold it over the waste cup and flush it with clean water from your eyedropper. Place it on a clean slide. To save your slide, follow the procedure described previ- ously.
