CIMOLIA ALBA, the official name of the earth of
which we now make tobacco-pipes. Its distinguishing
characters are, that it is a dense, compact, heavy
earth, of a dull white colour, and very close texture;
it will not easily break between the fingers, and slightly
stains the skin in handling. It adheres firmly to the
tongue; melts very slowly in the mouth, and is not
readily diffusible in water. It is found in many places.
That of the Isle of Wight is much esteemed for its col-
our. Great plenty of it is found near Pole in Dorset-
shire, and near Wedenbury in Staffordshire.
