 AMPHIBIANS
   Amphiuma—
(The Congo Eel) Slides prepared from the tissues of this animal are popular at all skill levels due to the unusu­ ally large size of its cells. Preparations that would usually require medium to high power can be viewed under low to medium power. Recommended for beginning microscopists.

 MAMMALIAN HISTOLOGY (EPITHELIAL TISSUE)
    Plant vs. Animal— ComparisetTM
What comparison in biol­ ogy is more fundamental than that between plants and animals? The slides in this set can be used to take this comparison to a different level—micro­ scopic. Epidermal cells from onion leaf are compared and contrasted with those from a human— cells whose similarities in structure are due to simi­ larities in function. Cross sections of pine stems are compared and contrasted with cross sections from an earthworm—both of which have structures specialized for conducting materi­ als through the organism. These and many other points can be made with this set of four slides.
