452. oldal - The luminous matter, in all situations, so far from possessing phosphoric properties, is incombustible, and loses the quality of emitting light, by being dried, or much heated. — The exhibition of light, however long it may be continued, causes no diminution of the bulk of the luminous matter. It does not require the presence of pure air, and is not extinguished by other gasses.
168. oldal - The northern sun creeping at midnight at the distance of five diameters along the horizon, and the immeasurable ocean in apparent contact with the skies, form the grand outlines in the sublime picture presented to the astonished spectator. The incessant cares and pursuits of anxious mortals are recollected as a dream ; the various forms and energies of animated nature are forgotten ; and the earth is contemplated only in its elements, and as constituting a part of the solar system.
451. oldal - The power of shewing light resides in a peculiar substance or fluid, which is sometimes situated in a particular organ, and at others diffused throughout the animal's body. — The light is differently regulated, when the luminous matter exists in the living body, and when it is abstracted from it.

In the middle of the cone forming the water-spout, there is a white transparent tube, which becomes less distinct on approaching it, and it is then discovered to be a vacant space in which none of the small particles of water ascend ; and in this, as well as around the outer edges of the waterspout, large drops of rain precipitate themselves. In calm weather, waterspouts generally...

But they adopted the error of Ptolemy in supposing that the southern parts of Africa and Asia joined ; for Edrisi describes an extensive country, extending from the coast of Africa to that of India, beyond the Ganges. The island of Madagascar seems to be faintly pourtrayed by them ; and it is certain that Arabian colonies and the...
23. oldal - Those who contend for there being no color at all, may remind us that the blue rays are the most refrangible, and that, being reflected in greatest quantity by the fluid, (which, because of its density and depth, causes them to undergo a strong refraction,) they cause a tint which is only apparent. Be that as it may, seamen admit of one conclusion — namely, that a green hue is a general indication of soundings, and indigo-blue of profound depth.
xx. oldal - Sea;" in 1819, he edited a new edition, with many corrections and a supplement, of Mackenzie's well-known " Treatise on Marine Surveying :" and, subsequently, his " Compendium of the Winds ;'' and (in conjunction with Mr. Arrowsmith), his " East India Pilot, of general and particular charts (on the largest scale ever published), from England to the Cape of Good Hope, Bombay, Madras, and China.
10. oldal - Commencing at the northern extremity of our hemisphere, we see the Northern Frozen Ocean, or Arctic Sea, surrounding the North Pole, and washing the northern extremities of both the old and new continents, its limits being the polar circle.
