He entered her room, emitting enough of his power to hide him from her senses.
Firefly is a term popularly used for certain tropical American click-beetles (Pyrophorus), due to their power of emitting light.
Wehnelt discovered that the same effect could be produced by using instead of a carbon filament a platinum wire covered with the oxides of calcium or barium, which when incandescent have the property of copiously emitting negative ions.
It is as far as possible from being true that a body emitting homogeneous light would disappear on merely covering half the aperture of vision with a half-wave plate.
In strictness this idea is appropriate only when the source is a luminous line, emitting cylindrical waves, such as might be obtained from a luminous point with the aid of a cylindrical lens.
T intervals, varying from a few weeks or months to a few years, has broken out into eruption, sometimes emitting only steam, ist and scoriae, but frequently also streams of lava.
Has both a summit and a lateral crater, which are apparently connected and perpetually emitting steam.
Two of the five compartments into which it is divided by walls of deeply striated volcanic ash are constantly emitting steam, while a new vent displaying great activity has been opened at the base of the cone on the south side.
With the gas in excess a heavy lurid flame emitting dense volumes of smoke results, whilst if it be driven out in a sufficiently thin sheet, it burns with a flame of intense brilliancy and almost perfect whiteness, by the light of which colours can be judged as well as they can by daylight.
It fuses at 62.5°C. (Bunsen) and boils at 667°, emitting an intensely green vapour.
- The same spectrum may show differences according to the physical conditions under which the body emitting the spectrum is placed.
Neville), and boils at about lioo C. Magnesium and its salts are diamagnetic. It burns brilliantly when heated in air or oxygen, or even in carbon dioxide, emitting a brilliant white light and leaving a residue of magnesia, MgO.
Itura, for example, belonging to the former, has protrusible scent-emitting processes at the end of the abdomen; and Thyridia has scent-producing tufts of hair on the edge of the posterior-wing.
In the Maribios district occur several volcanic lakelets, such as that of Masaya, besides numerous infernillos, low craters or peaks still emitting sulphurous vapour and smoke, and at night often lighting up the whole land with bluish flames.
It crystallizes from water in large prisms which melt at 168-170° C., and on further heating gives an anhydride and finally chars, emitting a characteristic odour and forming pyroracemic and pyrotartaric acids.
- Many Crustacea belonging to very different groups (Ostracoda, Copepoda, Schizopoda, Decapoda) possess the power of emitting light.
The name has no reference to the appearance of the body to the eye; when emitting energy, its radiations will he of all wave-lengths, and if intense enough will appeal to the eye as luminous between about wave-lengths 7600 and 4000 tenth-metres; this intensity is a question of temperature, and as it is exquisitely inappropriate to speak of the bulk of the solar radiations as black, the writer will speak instead of amorphous radiations from an ideal radiator.
"If anyone comes meddling again," said he, emitting the words separately through his thin compressed lips, "I will throw him down there.
I even manage to put a little aside and to send something to my father, he went on, emitting a smoke ring.
That's the way, Count, said Berg, lighting his pipe and emitting rings of smoke.
