Page 287 - The final result, therefore, of the mechanical theory is, that the only system of rings which can exist is one composed of an indefinite number of unconnected particles, revolving round the planet with different velocities according to their respective distances.
Page 308 - Its character is essentially the game as that of the parallel-wire micrometer; but it has some peculiarities, not, it is believed, previously introduced, and on which its wide range depends. The most remarkable of these peculiarities consists in its being furnished with two eye-pieces, composed of small single lenses, mounted in separate frames, which slide in a groove, and can be separated to the required distance. A frame carrying two parallel spider-lines, each mounted separately with its own...
Page 282 - We may draw the conclusion more formally as follows : — If the rings were solid and uniform, their motion would be unstable, and they would be destroyed ; but they are not destroyed, and their motion is stable, therefore they are either not uniform or not solid.

Page 189 - West at the same transit. The second principle was the substitution of a level or system of levels for the usual plumbline. The third principle was the casting in one piece, as far as practicable, of each of the different parts of the instrument, in order to avoid the great number of screws and fastenings with which most instruments are hampered, and to secure, if possible, perfect rigidity.
Page 336 - Though there seems to be no question that the dark space so frequently included in the tails of great comets is the result of a hollow structure, an attentive consideration of the appearances exhibited by the comet of Donati has led me to think it probable that some other cause may concur in its production. The ordinary laws of perspective certainly seem inadequate to its explanation, except in cases in which the darkness bears a large proportion to the brighter streams on each side of it: for unless...
