In that strip of reddish colour which runs along the cliffs of Suffolk,
and is called the Redcrag, immense quantities of cetacean remains have
been found. Four different kinds of whales, little inferior in size to
the whalebone whale, have left their bones in this vast charnel-house.
In 1840, a singularly perplexing fossil was brought to Professor Owen
from this Redcrag. No one could say what it was. He determined it to
be the tooth of a cetacean, a unique specimen. Now the remains of
cetaceans in the Suffolk crag have been discovered in such enormous
quantities, that many thousands a-year are made by converting them into
manure.
