Allied to the Forams, but distinguished by the radiating, needle-like contour of their false feet and the flinty texture of their shells, are an equally numerous assemblage of organisms known as Radiolarians. Like the Forams, they are inhabitants of the sea, and their discarded shells enter extensively into the constitution of strata. A little globular fresh-water form, devoid of a shell, and with slender bristle-like feet radiating in every direction, is known as the Sun-animalcule, and forms a connecting-link between the last two groups.
From Man to Egg-laying Mammals, Molluscs to Animalcules, the vast scheme of the Animal Creation has now been successively portrayed. With such simple gelatinous life-specks as the Amœba and its allies The Living Animals of the World make their exit: unorganised organisms, groping blindly in the darkness—"Sans teeth, sans eyes, sans taste, sans everything."
