LEFT SEA ANEMONE 311 SEA EAGLE Southern, 840,000 in the Antarctic, and 40,000 in the Pacific. Radiolarian ooze in like manner con- tains a varying proportion of siliceous remains, in this case principally Radio- laria and their fragments. Calcareous organisms and mineral particles are nearly always present in both these oozes, being usually more numerous and the mineral particles larger in the diatom ooze than in the radiolarian ooze, which latter generally occurs in greater depths than the former. Radiolarian ooze covers about 2,290,000 square miles— 1,161,000 in the Pacific, and 1,129,000 in the Indian ocean. Red clay occupies nearly the whole of the deeper abysses of the ocean, occurring in its most characteristic form in the central regions of the Pacific, far re- moved from continental land. It is of a reddish or chocolate color, due to the presence of the oxides of manganese and iron. Mineral particles of secondary ori- gin, arising from the decomposition of volcanic debris, are associated with the red clay, and in some regions of the central Pacific isolated crystals and spheroidal groups of phillipsite of secon- dary origin formed in situ make up a considerable quantity of the deposit. The presence of the remains of vertebrates, some of them belonging to extinct species lying alongside others belonging to exist- ing species, as well as the formation of manganese nodules and zeolitic crystals in situ, and the presence of metallic and chondritic spherules of cosmic origin, ap- pear to indicate that the red clay accu- mulates at a very slow rate. Red clay covers about 51,500,000 square miles — 37,230,000 in the Pacific, 5,800,000 in the Atlantic, 4,350,000 in the Southern, and 4,120,000 in the Indian ocean. SEA ANEMONE, the popular name given to a number of animals of the sub- kingdom Ccelenterata and class Actino- zoa, including the genus Actinia and other genera. All sea anemones, however varied in coloration or form, present the essential structure and appearance of a fleshy cylinder, attached by its base to a rock or stone, and presenting at its free extremity the mouth, surrounded by a circlet of arms or tentacles. With these tentacles, which may be very numerous, in some cases exceeding 200 in number, they seize and secure their food — small Crustacea, mollusks, such as whelks, etc. — which they paralyze by means of the thread cells common to them with all Ccelenterata. The mouth leads into a stomach sac. When fully expanded, the appearance of the anemones in all their varieties of color is exceedingly beautiful. But on the slightest touch the tentacles can be quickly retracted within the mouth aperture, the fluids of the body are ex- pelled by the mouth, and the animal, from presenting the appearance of a fully expanded flower, becomes a conical mass of jelly-like matter. They are, most of them, dioecious, that is, having the sexes situated in different individuals. The young are developed within the parent body, and appear in their embryo state as free swimming ciliated bodies of an oval shape. The sea anemones resemble the Hydrse in their marvelous powers of resisting injuries and mutilation. They are eaten as food in Italy, Greece and on various coasts. SEABTJBY, SAMUEL, an American clergyman; born in Groton, Conn., Nov. 30, 1729; was graduated at Yale in 1748; studied medicine at Edinburgh; and re- ceived deacon's and priest's orders in England in 1753. For some time he was a missionary of the S. P. G. ; in 1757 he was promoted to the "living" of Jamaica, Long Island, and 10 years later to that of Westchester, N. Y. The Whigs, how- ever, prevented his ministering, and once imprisoned him for six weeks at New Haven. He removed to New York, where he made his medical knowledge contribute to his support, acted as chaplain of the King's American regiment, and wrote a series of pamphlets which earned for him the special hostility of the patriots. On March 25, 1783, the clergy of Connecti- cut met at Woodbury and elected Sea- bury bishop; and for 16 months he waited vainly in London for consecration, the archbishops being indisposed to move without the sanction of the civil author- ity. On Nov. 14, 1784, he was consecrated at Aberdeen by bishops of the Scotch Episcopal Church. Bishop Seabury's jurisdiction embraced Rhode Island as well as Connecticut, and he acted also as rector of St. James' Church, New London. In 1792 he joined with three bishops of the English succession in con- secrating a fifth, Bishop Claggett, through whom every American bishop derives from Seabury and the Scotch Church. Seabury secured to the episcopate its proper share in the government of the Church, and the restoration of the obla- tion and invocation to the Communion Office (from the Scotch Office). He died Feb. 25, 1796. SEA EAGLE, a name applied to one or two members of the eagle family; but , probably with most distinctive value to the cinereous or white-tailed eagle or erne, Haliaetus albicilla, found in all parts of Europe. It is generally found inhabiting the seacoasts, and though liv- ing mainly on fish, yet makes inland jour-
