Pagina 507 - The island is five miles in length, and one in breadth, and has a flat surface nearly eighty feet above the sea. On all sides, except the north, it is bounded by perpendicular cliffs about fifty feet high, composed entirely of dead coral, more or less porous, honeycombed at the surface, and hardening into a compact, calcareous substance within, possessing fracture of secondary limestone, and has a species of millepore interspersed through it.
Pagina 460 - Encrinites as a corn-rick is composed of straws. Man applies it to construct his palace and adorn his sepulchre ; but there are few who know, and fewer still who duly appreciate, the surprising fact, that much of this marble is composed of the skeletons of millions of...
Pagina 142 - Mantis religiosa, the Praying Mantis, or Soothsayer ; and is termed by the French prie-Dieu. This is regarded by the Turks as an object of superstitious veneration; and many absurd stories are on record, in regard to its habits.

If, while the hydra is floating in this manner, suspended by the extremity of the foot, a drop of water be made to fall upon that part, so as to wet it, this hydrostatic power will be destroyed, and the animal will immediately sink to the bottom.
Pagina 532 - We scarcely condescend,•" observes Lamarck in reference to this fact, " to examine microscopic shells, from their insignificant size ; but we cease to think them insignificant when we reflect, that it is by means of the smallest objects that Nature everywhere produces her most remarkable and astonishing phenomena. Whatever she may seem to lose in point of volume in the production of living bodies. is amply made up by the number of the individuals, which she multiplies with admirable promptitude...
Pagina 550 - Polirschiefer, or polishing slate of Bilin in Bohemia, which occupies a surface of great extent, probably the site of an ancient lake, and forms slaty strata of fourteen fe"et in thickness, almost wholly composed of the silicified shields of animalcules.
Pagina 244 - Their habits are mostly aquatic ; but, in consequence of the manner in which their gills are inclosed, none of them are killed at once by being withdrawn from the water ; and some of them pass the greatest part of their lives in air. They are naturally voracious and carnivorous...
Pagina 347 - ... and precision than the modern Decapod Dibranchiata. The position of the animal was, most probably, more habitually vertical than that of its recent congeners. Thus placed, the Belemnite, in quest of prey, would rise swiftly or stealthily to infix its claws in the belly of a supernatant fish, and then dart down, and drag its prey to the bottom and devour it.
