Popular passages
Page 285 - On partially liquefying carbonic acid by pressure alone, and gradually raising at the same time the temperature to 88° F., the surface of demarcation between the liquid and gas became fainter, lost its curvature, and at last disappeared. The space was then occupied by a homogeneous fluid, which exhibited, when the pressure was suddenly diminished or the temperature slightly lowered, a peculiar appearance of moving or flickering striae throughout its entire mass.
Page 183 - It seems possible to account for all the phenomena of heat, if it be supposed that in solids the particles are in a constant state of vibratory motion, the particles of the hottest bodies moving with the greatest velocity...
Page 145 - For instance, the orange ray may be the effect of the strontia, since Mr. Herschel found in the flame of muriate of strontia a ray of that colour. If this opinion should be correct, and applicable to the other definite rays, a glance at the prismatic spectrum of a flame may show it to contain substances which it would otherwise require a laborious chemical analysis to detect.
Page 194 - ... with it, which moves upon the face of the arc, and subdivides the former graduation into minutes of a degree ; the other end crosses the centre, and terminates in an obtuse steel point, turned inwards at a right angle.
Page 365 - F, a communication be established between the two vessels, part of the current will pass through this wire and return to the pile. The quantity of electricity circulating in the galvanometer will be thus diminished, and with it the deflection of the needle. Suppose, then, that by this artifice we have reduced the galvanometric deviation to its fourth or fifth part ; in other words, supposing that the needle being at 10 or 12 degrees, under the action of a constant source of heat, placed at a fixed...
Page 144 - The colours thus communicated by the different bases to flame afford, in many cases, a ready and neat way of detecting extremely minute quantities of them...
Page 351 - ... inch above the other ; discharge a large jar through the card. It will be perforated opposite the wire attached to the negative coating, and an irregular dark line of reduced mercury will be found extending on the positive side to the point of the positive wire. If the experiment be made in vacuo, the perforation will be formed midway between the two wires. The distinction between positive and negative electricity is also beautifully shown by what are termed Lichtenberg's figures, which may be...
Page 285 - ... liquefaction of carbon dioxide or separation into two distinct forms of matter can be effected, even under a pressure of 300 or 400 atmospheres. Similar results are obtained with nitrous oxide. It appears indeed that there exists for every liquid a temperature, called by Andrews the
Page 177 - Substances are said to be optically active when they produce rotation of the plane of polarisation of a ray of polarised light which passes through them. The rotation may be either to the right or to the left, according to the nature of the substance ; in the former case the substance is said to be dextro-rotatory ; in the latter, Izvo-rotatory.
Page 366 - The other forces are easily obtained by the proportions : — 1-5 : 5=a : x=— a=3-333 a 1*5 (that is to say, one reduced current is to the total current to which it corresponds, as any other reduced current is to its corresponding total current), where a represents the deflection when the exterior circuit is closed.
