CORAL AND CORAL REEFS*
by Thomas H. Huxley

*[Foonote] A Lecture delivered in Manchester, November 4th, 1970.
THE subject upon which I wish to address you to-night is the structure
and origin of Coral and Coral Reefs. Under the head of "coral" there
are included two very different things; one of them is that substance
which I imagine a great number of us have champed when we were
very much younger than we are now,--the common red coral, which is
used so much, as you know, for the edification and the delectation of
children of tender years, and is also employed for the purposes of
ornament for those who are much older, and as some think might know
better. The other kind of coral is a very different substance; it may for
distinction's sake be called the white coral; it is a material which most
assuredly not the hardest-hearted of baby farmers would give to a baby
to chew, and it is a substance which is to be seen only in the cabinets of
curious persons, or in museums, or, may be, over the mantelpieces of
sea-faring men. But although the red coral, as I have mentioned to you,
has access to the very best society; and although the white coral is
comparatively a despised product, yet in this, as in many other cases,
the humbler thing is in reality the greater; the amount of work which is
done in the world by the white coral being absolutely infinite compared
with that effected by its delicate and pampered namesake. Each of these
substances, the white coral and the red, however, has a relationship to
the other. They are, in a zoological sense, cousins, each of them being
formed by the same kind of animals in what is substantially the same
way. Each of these bodies is, in fact, the hard skeleton of a very curious
and a very simple animal, more comparable to the bones of such
animals as ourselves than to the shells of oysters or creatures of that
kind; for it is the hardening of the internal tissue of
