Página 19 - With an unimportant exception, the candles are also made of what I beg to designate as vegetable stearine. When the candles, which are made by dipping, are of the required diameter, they receive a final dip into a mixture of the same material and insect-wax, by which their consistency is preserved in the hottest weather.
Página 71 - Supposing it all at mean temperature, the lines of force would have the direction determined by the arrangement of the power within the earth. Then the sun's presence in the east would make all the atmosphere in that region a worse conductor, and cause it to assume the character of D ; and as the sun came up to and passed over the meridian and away to the west, the atmosphere under his influence would bring up changes in direction like those shown in either D or D ; it would therefore manifestly...
Página 165 - Some writers, scouting the idea that reefs of rocks can be due in any way to " animalcules," talk of electrical forces, the first and last appeal of ignorance. Others call in the fishes of the seas, suggesting that they are the masons, and work with their teeth in the accumulation of the calcareous material. Very many of those who discourse quite learnedly on zoophytes and reefs, imagine that the polyps are mechanical workers, heaping up these piles of rock by their united labors ; and science still...
Página 293 - The Smithsonian Institution is also desirous of obtaining detailed lists of all the animals and plants of any locality throughout this continent. These, when practicable, should consist of the scientific names, as well as those in common use; but when the former are unknown, the latter may be employed.
Página 169 - Trees of coral are well known ; and although not emulating in size the oaks of our forests, — for they do not exceed six or eight feet in height, — they are gracefully branched, and the whole surface blooms with coral polyps in place of leaves and flowers. Shrubbery, tufts of rushes, beds of pinks, and feathery mosses, are most exactly imitated. Many species spread out in broad leaves or folia, and resemble some large-leaved plant just unfolding: when alive, the surface of each leaf is covered...

With these precautions I have found this test astonishingly delicate, in fact, ranking with those for iron, iodine, &c. Using fused nitre, I have detected the presence of 1 pt. in 017,000 pts.

Página 157 - In the meantime, the boulders and angular fragments brought down the ravines and river by the floods, are being cemented into a firm conglomerate so that it is difficult to dislodge even a small pebble, the pebble itself sometimes breaking before the cementation yields.
Página 269 - Tyndall accordingly concludes that " if the arrangement of the component particles of any body be such as to present different degrees of proximity in different directions, then the line of closest proximity, other circumstances being equal, will be that chosen by the respective forces for the exhibition of their greatest energy. If the mass be [para] magnetic, this line will stand axial; if diamagnetic, equatorial."2 1 Tyndall on Diamagnetism, p.
