until 1892, when she became president. For casting a vote in the
presidential election of 1872, as, she asserted, the Fourteenth
Amendment to the Federal Constitution entitled her to do, she was
arrested and fined $100, but she never paid the fine. In collaboration
with Mrs Elizabeth Cady Stanton, Mrs Matilda Joslyn Gage, and Mrs Ida
Husted Harper, she published _The History of Woman Suffrage_ (4 vols.,
New York, 1884-1887). She died at Rochester, New York, on the 13th of
March 1906.

ANTHOZOA (i.e. "flower-animals"), the zoological name for a class of
marine polyps forming "coral" (q.v.). Although corals have been familiar
objects since the days of antiquity, and the variety known as the
precious red coral has been for a long time an article of commerce in
the Mediterranean, it was only in the 18th century that their true
nature and structure came to be understood. By the ancients and the
earlier naturalists of the Christian era they were regarded either as
petrifactions or as plants, and many supposed that they occupied a
position midway between minerals and plants. The discovery of the animal
nature of red coral is due to J.A. de Peyssonel, a native of Marseilles,
who obtained living specimens from the coral fishers on the coast of
Barbary and kept them alive in aquaria. He was thus able to see that the
so-called "flowers of coral" were in fact nothing else than minute
polyps resembling sea-anemones. His discovery, made in 1727, was
rejected by the Academy of Sciences of France, but eventually found
acceptance at the hands of the Royal Society of London, and was
published by that body in 1751. The structure and classification of
polyps, however, were at that time very imperfectly understood, and it
was fully a century before the true anatomical characters and systematic
position of corals were placed on a secure basis.

The hard calcareous substance to which the name coral is applied is the
supporting skeleton of certain members of the _Anthozoa_, one of the
classes of the phylum Coelentera. The most familiar Anthozoan is the
common sea-anemone, _Actinia equina_, L., and it will serve, although it
does not form a skeleton or _corallum_, as a good example of the
structure of a typical Anthozoan polyp or zooid. The individual animal
or zooid of _Actinia equina_ has the form
