For a further account of Halley's astronomical labours, we may refer to the History of Astronomy in the Library of Useful Knowledge, page 79. We must also ascribe to Halley the first correct application of the barometer to the measurement of the heights of mountains.

Page 5 - Thomson gives this illustration : — ' Imagine a drop of rain, or a glass sphere the size of a pea, magnified to the size of the earth, the molecules in it being increased in the same proportion. The structure of the mass would then be coarser than that of a heap of fine shot, but probably not so coarse as that of a heap of cricket -balls.
Page 134 - The siphon barometer has no cistern, but consists of a bent glass tube (fig. 125), one of the branches of which is much longer than the other. The longer branch, which is closed at the top, is filled with mercury as in the cistern barometer ; while the shorter branch, which is open, serves as a cistern. The difference between the two levels is the height of the barometer.
Page 361 - ... ether. The luminosity of a body is due to an infinitely rapid vibratory motion of its molecules, which, when communicated to the ether, is propagated in all directions in the form of spherical waves ; and this vibratory motion, being thus transmitted to the retina, calls forth the sensation of vision. The vibrations of the ether take place not in the direction of the wave, but in a plane at right angles to it.
