ous sizes. A small dissecting dish may be
made by pouring melted paraffin wax into one of those shallow china
pots chemists use for cold-cream, and tadpoles may be pinned out
with entemologists' pins and dissected with needles. But this is a
work of supererogation. Partially incubated hen's eggs may be
obtained at a small cost almost anywhere, and the later stages
profitably examined and dissected under warm water. For a clear
understanding of the allantois and amnion, this last is almost
indispensable. A few microscopic slides of sections of embryonic
chicks should also be compared with our rough diagrams.
