An
interesting and popular way of mounting and displaying various small individual
objects was by selecting and positioning them into groups, usually geometric or
patterned arrangements. Slides were made up using a wide variety of
microscopic objects,
including foraminifera, radiolaria, diatoms, insect and butterfly
scales, seeds, sponge spicules, etc. One can only imagine the skill
and patience required! Preparations were produced for both reflected
(top lighting) and transmitted lighting. Photomicrographs of
arrangements are from the slides shown. Note that some of these
could just as well be considered as Exhibition slides, which are covered
further on the "Exhibition" page. |
