Page 168 - ... between the poles (not as yet magnetized by the electric current), so that the polarized ray should pass through its length; the glass acted as air, water, or any other indifferent substance would do; and if the eye-piece were previously turned into such a position that the polarized ray was extinguished, or rather the image produced by it rendered invisible, then the introduction of this glass made no alteration in that respect.
Page 176 - Dry the paper cautiously at a distant fire, or else let it dry spontaneously in a dark room. When dry, or nearly so, dip it into a solution of iodide of potassium containing 500 grains of that salt dissolved in one pint of water, and let it stay two or three minutes in this solution.
Page 478 - Normally the first production contract will have more changes than the second, the second more than the third, and so on.
Page 177 - The shadows are thus rendered too dark, and the lights are not sufficiently white. The drawing is then washed, and plunged into a bath of iodide of potassium, of the strength of 500 grains to each pint of water, and allowed to remain in it for one or two minutes, which makes the pictures brighter, and its lights assume a pale-yellow tint.
Page 179 - I placed upon a plate of copper, blue, red, and orange coloured glasses, pieces of crown and flint glass, mica, and a square of tracing paper. These were allowed to remain in contact half an hour. The space occupied by the red glass was well marked, that covered by the orange was less distinct, but the blue glass left no impression ; the shapes of the flint and crown glass were well made out, and a remarkably strong impression where the crown...
Page 168 - Between the polarizing mirror and the eye-piece, two powerful electro-magnetic poles were arranged, being either the poles of a horse-shoe magnet, or the contrary poles of two cylinder magnets ; they were separated from each other about two inches in the direction of the ray, and so placed that, if on the same side of the polarized ray, it might pass near them ; or if on the contrary sides, it might go between them, its direction being always' parallel or nearly so to the magnetic lines of force.
Page 426 - ... lower extremities were open ; they were arranged in pairs in separate vessels of dilute sulphuric acid, and of each pair one tube was charged with oxygen, the other with hydrogen gas, in quantities such as would allow the platinum to touch the dilute acid ; the platinum in the oxygen of one pair was metallically connected with the platinum in the hydrogen of the next, and a voltaic series of fifty pairs was thus formed. With this battery the following effects were produced : — 1st.
Page 516 - ... in these lines. After noticing the magne-crystallic condition of various bodies, the author enters upon a consideration of the nature of the magne-crystallic force. In the first place he examines closely whether a crystal of bismuth has exactly the same amount of repulsion, diamagnetic or otherwise, when presenting its magne-crystallic axis parallel or transverse to the lines of magnetic force acting on it For this purpose, the crystal was suspended either from a torsion balance, or as a pendulum...
Page 517 - ... concludes, that the force manifested in the magnetic field, which appears by external actions and causes the motion of the mass, is chiefly, and almost entirely induced, in a manner subject indeed to the crystalline force and additive to it ; but at the same time exalting the force and the effects to a degree which they could not have approached without the induction. To this part of the force he applies the word...
