“Schleicher addresses himself, previously took occasion, in his splendid monograph on the 'Radiolaria', * to express his high appreciation of, and general concordance with, Mr. Darwin's views.”
“I know of no more solid and important contributions to biology in the past seven years than Haeckel's work on the "Radiolaria," and the researches of his distinguished colleague Gegenbaur, in vertebrate anatomy; while in”
“Beneath tropical seas, in depths of 1000 to 1500 fathoms, calcareous oozes cover nearly a third of the ocean floor; while the colder waters of the temperate and polar regions release to the underlying bottom the siliceous remains of diatoms and Radiolaria.”
“These silicious bodies belong partly to the lowly vegetable organisms which are called Diatomaceae, and partly to the minute, and extremely simple, animals, termed Radiolaria.”
“But if the Radiolaria and Diatoms are thus rained upon the bottom of the sea, from the superficial layer of its waters in which they pass their lives, it is obviously possible that the”
“The skeletons of the full-grown, deep - sea Globigerinae are so remarkably solid and heavy in proportion to their surface as to seem little fitted for floating; and, as a matter of fact, they are not to be found along with the Diatoms and Radiolaria, in the uppermost stratum of the open ocean.”
“Radiolaria, which peopled in inconceivable multitudes the tertiary oceans; and, as they died, their minute skeletons fell down in a continuous rain upon the ocean bed, and became cemented into solid rock which geologic action has brought to the surface in Barbados and many other parts of the earth.”
“Foraminifera, the siliceous beds are made of Radiolaria, sponge spicules and diatoms, while the red clay closely resembles the red clay of the deepest parts of the oceans.”
“Take away the cysts which characterize the Radiolaria, and a dead Sphaerozoum would very nearly represent one of this deep-sea “Urschleim,” which must, I think, be regarded as a new form of those simple animated beings which have recently been so well described by”
“Radiolaria, those magical creatures of the sea, which are so small that they can be seen only with a powerful microscope, but which look like living snow-crystals, although a thousand times more beautiful.”
