Suspended by a cord from the ceiling in the centre of this room was a glass ball, filled with water, used by Mr. Mitchell in his experiments on polarization of light, flashing its dancing rainbows about the room.

Under ordinary circumstances this substance exerted no unusual action on light, but when it was placed between the poles of a powerful electro-magnet, and the light was passed through it in the same direction as the magnetic flux, the plane of polarization of the light was rotated in a certain direction.

Kerr has proved that a beam of light passed through an extremely thin plate of highly magnetic iron has its plane of polarization slightly rotated.

I had attempted some optical experiments in the summer, especially on the polarization of sky-light; but had been too busy with the Observatory to continue them.

"The Lectures as begun in 1827 included ordinary Mechanics, ordinary Hydrostatics and Pneumatics (I think that I did not touch, or touched very lightly, on the subjects connected with the Hydraulic Ram), and ordinary Optics (with a very few words on Polarization and Depolarization).

In 1830 I believe I went (in addition to what is mentioned above) into Polarization and Depolarization of all kinds.

I had no time to make observations of polarization, &c., although prepared.

Soc. Experiments of Polarization.

This imponderable fluid or power, whatever it may be, whether one or two, or a polarization of one force into the states + and -, is one of the most active agencies known to man, and although not capable of being weighed in the balance, is not found wanting anywhere in Nature.

The word polarization, borrowed from optics, where it has an unequivocal sense, serves likewise to designate the development of the counter electro-motive force of galvanic elements, and also that essentially different condition of badly conducting substances that is brought about by the simultaneous influence of quantities of opposite electricity.

But the gyrostatic system does, besides, what the system of naturally acting material particles cannot doit constitutes an elastic solid which can have the Faraday magneto-optic rotation of the plane of polarization of light; supposing the application of our solid to be a model of the luminiferous ether for illustrating the undulatory theory of light.

As sugar nowadays is exclusively dealt with according to the degree of polarization, this fact is of enormous value in trade.

He has examined a great quantity of diabetic urine after three different methods, namely, Trommer's (alkaline solution of copper); by fermentation; and with the polarization apparatus.

He succeeded in isolating a substance corresponding in its chemical composition to grape sugar, and also a carbo-hydrate differing considerably from grape sugar, and turning the plane of polarization to the left.

They are similar in chemical constitution, but the one is the reverse of the other when examined by polarized lightthat is, they rotate the plane of polarization of a ray of light in opposite ways.

Revolution in the fourth dimension would also explain the change in a body from producing a right-handed, to producing a left-handed, polarization of light.

For instance: if we tell them that in 1820 he wrote a paper "On the Theory and Summation of Series;" communicated to the Cambridge Philosophical Society his discovery that the two kinds of rotatory polarization in rock crystal were related to the plagihedral faces of that mineral; and issued an able treatise "On Certain Remarkable Instances of Deviation from Newton's Tints in the Polarized Tints of Uniaxal

Having pursued with much zeal the study of optics, and experimented largely and carefully on the double refraction and polarization of light, he compiled a treatise on the subject for the "Encyclopaedia Metropolitana"

SPOTTISWOODE, WILLIAM, mathematician and physician, born in London; was Queen's printer, as his father had been before him; published numerous important papers on scientific subjects, his greatest work "The Polarization of Light," a subject on which he was a great authority (1825-1883).

It is caused by a polarization of the particles composing the astral substance, which manifest in a current of intense vibrations in the astral substance, which thus serve as a ready channel for the transmission of psychic force or astral energy.

It may be said to partake somewhat of the nature of the magnetization of a bar of steel; for it consists in what we might call the polarization, by an effort of the human will, of a number of astral atoms reaching from the operator to the scene which he wishes to observe.
