He accounts for the relation of the masses and the densities of the planets to their distances from the sun, for the eccentricities of their orbits, for their rotations, for their satellites, for the general agreement in the direction of rotation among the celestial bodies, for Saturn's ring, and for the zodiacal light.

These are densities of population equal to having 348,000, 664,000, and 1,008,829 people on a square mile.

That is, whenever there are two solutions of different densities, separated only by an animal membrane, an interchange will take place between them through the membrane.

In a similar manner two gases, especially if of different densities, may mingle even when separated from each other by a membrane.

There was also much work on important subjects more or less connected with his official dutiessuch as geodetical survey work, the establishment of time-balls at different places, longitude determinations, observation of eclipses, and the determination of the density of the Earth.

This knowledge he afterwards utilized very effectively at the Harton Pit in comparing the density of the Earth's crust with its mean density; and it was very useful to him in connection with geodetic surveys and experiments on which he was consulted.

In mathematics I find Chances, Figure of the Earth with variable density, Differential Equations, Partial Differentials, sketch for an instrument for shewing refraction, and Optical instruments with effects of chromatic aberration.

In mathematics I find investigations of Motion in a resisting medium, Form of Saturn, Draft of a Paper about an instrument for exhibiting the fundamental law of refraction (read at the Philosophical Society by Mr Peacock on Nov. 10th, 1823), Optics, Solid Geometry, Figure of the Earth with variable density, and much about attractions.

"On Feb. 4th I have investigations of the density of light near a caustic (on the theory of emissions).

I have notes about a Paper on the connection of impact and pressure, read at the Philosophical Society on Nov. 14th, but not printed, dipping-needle problems, curve described round three centres of force, barometer observations, theory of the Figure of the Earth with variable density, and effect on the Moon, correction to the Madras pendulum, wedge with friction, spots seen in my eyes, density of rays near a caustic.

Considering the density of the forests, one may as easily take a general sketch of a room from underneath the carpet as of Trinidad from the ground.

When the rays of the sun have been beating on the ground during the day, currents of hot air of different temperatures, and consequently of different densities, are constantly ascending from the ground and mixing with the cold air above.

Analogous effects are produced when sound passes through a mixed medium, whether it consists of two different mediums or of one medium where portions of it have different densities.

As sound moves with different velocities through media of different densities, the wave which produces the sound will be partly reflected in passing from one medium to the other, and the direction of the transmitted wave changed; and hence in passing through such media different portions of the wave will reach the ear at different times, and thus destroy the sharpness and distinctness of the sound.

Increase in height and density of crown cover is due to the development of the younger twigs.

The chimney is not only an apparatus designed to carry off the smoke and gases due to combustion, for its principal role is to break the equilibrium of the atmospheric air, which is the great reservoir of oxygen, and to suck into the flame, through the difference of densities, this indispensable agent to combustion.

By the hypothesis, equality of temperature between two different gases or two portions of the same gas at different densities means equality of kinetic energies in the same number of molecules of the two.

Between the parts of opaque and coloured bodies are many spaces, or pores, either empty or filled with media of other densities.

Hence it follows that the spheres, whether they are of uniform density, or consist of concentric layers of varying densities, will act upon each other in the same manner as if their force resided in their centres alone.

ENDOSMOSE, a word used in physics to describe the intermingling of two liquids of different densities, in close juxtaposition, but separated by a thin membranous tissue.
