CLEAVAGE
Uses differential interference-contrast
technique to show the penetration of a
sperm into an unfertilized egg, which
immediately reacts with raising of the
fertilized membrane. Demonstrates
migration of both pronuclei toward each
other and their fusion. Details

Documents formation and growth of
triaxial skeletal spicule from two small
calcite granula. Transforms gastrula into
first, the prism stage, and second, pluteus

METAMORPHOSIS
Shows the "dissolution" of the larval body
using time-lapse photography. The
transition from the bilateral symmetry of
the pluteus to the star-shaped radial
symmetry is explained in an animated
sequence. The metamorphosis is induced
by the addition of cesium chloride.

BIOLOGY BIOLOGY OF OF AN AN ASCIDI ASCIDIAN

(HALOCYNTH
(HALOCYNTHIA (HALOCYNTH IA RORETZI)
Covers the ascidian's life cycle and
structure, and uses microphotography,
time-lapse photography, and diagrams to
document in detail the organism from
fertilization to the larval stage, and then
through metamorphosis to the young adult
stage. Makes the point that ascidians, or
sea squirts, are of particular interest to
biologists because, from a phylo-genetic
point of view, they represent a group
between the vertebrates and the
invertebrates.

Examines the mineralogy, petrology, and
geologic development of southern Africa's
Bushveld Igneous Complex, the world's
largest and best-preserved layered
intrusion. Beginning with the filling of the
Transvaal Basin and the extrusion of the
Rooiberg Felsite, the film demonstrates
the emplacement of the main igneous
bodies, the development of the
metamorphic aureole, and the formation of
deposits of chromite, platinum, and other
minerals.

A
By Jacques Mitsch
For how long have we been laughing? Are
human beings the only ones to laugh? In
the past, scientists tended to neglect such
questions of laughter, leaving them to the
philosophers. Jacques Mitsch's A
NATURAL HISTORY OF LAUGHTER
explores recent scientific attempts to
explicate this most elusive of human
faculties, undertaken by scientists who
see it as a means of approaching some of
the larger mysteries of neurology and
human behavior.
