A third form of matter is produced from the original particles.

The light scattered from small particles is of a much richer blue than the blue of the first order as reflected from a very thin plate.

The only motion in the air was that of the dripping, microscopic particles of drizzling mist.

Consider the particles which occupy a thin stratum dx perpendicular to the primary ray x.

Comparison is effected by the use of particles.

It must not be forgotten, too, that a very moderate increase of dimensions may carry the particles beyond the reach of our approximations.

It is obvious that the aerial particles are illuminated not only by the direct solar rays, but also by light dispersed from other parts of the atmosphere and from the earth's surface.

So long as the precipitated particles are very fine, the light dispersed in a perpendicular direction is sky-blue and fully polarized.

At a further stage of their growth the particles disperse in the perpendicular direction a light which is no longer fully polarized.

When a current is passed through a solid alloy, a series of Peltier effects, proportional to the current, are set up between the particles of the different metals, and these create an opposing electromotive force which is indistinguishable experimentally from a resistance.

The peculiarity of organic and sentient bodies is due to the minuteness and shape of their particles, and to their special motions and combinations.

So, too, mind consists but of extremely fine particles of matter, and dissolves into air when the body dies.

By the aid of one front leg it places consecutive heaps of loosened particles upon its head, then with a smart jerk throws each little pile clear of the scene of operations.

Growing specimens of good colour and in fruit are if possible selected, and cleansed as much as practicable from adhering foreign particles, either in the sea or a rocky pool.

By considering only the particles of air found in a right line, he reduced the problem of the propagation of sound to the solution of the same partial differential equations that include the motions of vibrating strings, and demonstrated the insufficiency of the methods employed by both his great contemporaries in dealing with the latter subject.

The root is made to press its way into the darker cracks and crannies of the soil, so bringing its root-hairs into better contact with the particles round which the hygroscopic water hangs.

If too closely packed, the soil particles present mechanical obstacles to growth; if too retentive of moisture, the root-hairs suffer, as already hinted; if too open or over-drained, the plant succumbs to drought.

The water content of the soil, its mineral content, its humus content, its temperature, and its physical characteristics, such as its depth and the size of its component particles are all edaphic factors.

It is clear, however, that an equal quantitative division and distribution of the chromatin to the daughter cells is brought about; and if, as has been suggested, the chromatin consists of minute particles or units which are the carriers of the hereditary characteristics, the nuclear division also probably results in the equal division and distribution of one half of each of these units to each daughter cell.

These layers arc secreted by the protoplasm by the direct apposition of substances on those already in existence; and they may go on increasing in thickness, both by apposition and by the intussusception of particles probably carried in through the protoplasmic fibres, which penetrate the cell-wall as long as the cell lives.

As results of Roberval's labours outside the department of pure mathematics may be noted a work on the system of the universe, in which he supports the Copernican system and attributes a mutual attraction to all particles of matter; and also the invention of a special kind of balance which goes by his name.

As the sun loses heat it contracts, and every pair of particles in the sun are nearer to each other after the contraction than they were before.

Gauss had shown how to reduce all the phenomena of statical electricity to mere attractions and repulsions exerted at a distance by particles of an imponderable on one another.

He treated the resultant electric force at any point as analogous to the flux of heat from sources distributed in the same manner as the supposed electric particles.

But this was based upon the assumption of a distance-action between electric particles, the intensity of which depended on their relative motion as well as on their position.

Morgan sums up a discussion on Lubbock's experiments in which the ants failed to utilize particles of earth for bridge-making, with the suggestive remark that " What these valuable experiments seem to show is that the ant, probably the most intelligent of all insects, has no claim to be regarded as a rational being."

Having arrived at the conclusion that the food of plants consists of minute particles of earth taken up by their rootlets, it followed that the more thoroughly the soil in which they grew was disintegrated, the more abundant would be the " pasture " (as he called it) to which their fibres would have access.

After examining several hypotheses, he decides this to be fine particles of earth.

The last two are sometimes indicated by particles or auxiliary verbs; but these are generally dispensed with if the meaning is sufficiently plain without them.

Dry steam is steam free from mechanically mixed water particles; wet steam, on the other hand, contains water particles in suspension.

The colloidal particles are electrically charged and become discharged by the ions of sodium, magnesium and calcium present in the sea-water.

Corresponding with this result we find that the freezing point of dilute solutions indicates that two pressure-producing particles per molecule are present.

It should be pointed out that no measurements on osmotic pressures or freezing points can do more than tell us that an excess of particles is present; such experiments can throw no light on the question whether or not those particles are electrically charged.

That question can only be answered by examining whether or not the particles move in an electric field.

A body containing an excess of these particles is negatively electrified, and is positively electrified if it has parted with some of its normal number.

The leading products of the blast-furnace are argentiferous lead (base bullion), matte, slag and flue-dust (fine particles of charge and volatilized metal carried out of the furnace by the ascending gas current).

Thomson has demonstrated the existence under many different conditions of particles more minute than anything previously known to science.

A magnetizable substance was supposed to consist of an indefinite number of spherical particles, each containing equivalent quantities of the two fluids, which could move freely within a particle, but could never pass from one particle to another.

In order to the formation of a well-defined corona it is essential that the particles be exclusively, or preponderatingly, of one size.

The gold is found in minute particles arid in the richest ores the metal is rarely in visible quantities before treatment.

The subsequent experiments of Snellen, Senftleben, and, more lately, of Turner, seem to show that if the eyeball be protected from the impingement of foreign particles, an accident to which it is liable owing to its state of anaesthesia, the ulceration may be warded off indefinitely.

Among the most dangerous of the last class (the pneumokonioses) is perhaps that in which the dust particles take the form of finely divided freestone, as in stone-dressing and the dry-polishing on the grindstone of steel.

The particles in this case set up a form of fibrosis of the lung, which, either of itself or by rendering the organ liable to tubercular infection, is extremely fatal.

Melanine particles formed in the spleen in malaria, which pass along with the blood through the liver, are appropriated by the endothelial cells of the hepatic capillaries, and are found embedded within their substance.

Phagocytes act as scavengers in ridding the body of noxious particles, and more especially of harmful bacteria.

The "intestine movement of particles" in every body, or fermentation, was the explanation of many of the processes of life and disease.

The sensible properties and physical alterations of animal fluids and solids depended upon different proportions, movements and combinations of these particles.

Grains of gold or particles of ore may be detected by washing samples of gravel in a prospector's 1 Of doubtful origin.

If in the process of glass manufacture a glass vessel is suddenly cooled, the constituent particles are unable to arrange themselves and the vessel remains in a state of extreme tension.
