Pagina 140 - The diameter of the object-glass will be 3-4 inches, and its focal length 50 inches ; the image of the sun will be 0-465 inch, but the proposed eye-piece will, with a magnifying power of 25-8 times and focal length x, increase the image to 12 inches, the angle of the picture being about 13° 45'.
Pagina 42 - ... density than the crust, which, to avoid circumlocution, I will call lava. To fix our ideas, suppose the thickness of the crust to be ten miles through the greater part of the circumference, and therefore twelve miles at the place of the table-land. Now I say, that this state of things is impossible: the weight of the table-land would break the crust through its whole depth from the top of the table-land to the surface of the lava, and either the whole or only the middle part would sink into the...

Pagina 220 - Every well trained philosophical judgment is accustomed to observe illustrations of the most sublime phenomena of creation in the most minute and familiar operations of the Creator's laws, one of the most characteristic features of which consists in the absolute and wonderful integrity maintained in their action, whatsoever be the range as to magnitude or distance of the objects on which they operate. For instance, the minute particles of dew which whiten the...

Pagina 158 - ... and the marking out on it, in reference to the parallel to the equinoctial passing through its centre, the places, sizes, and forms of the spots, there would need, I should imagine, no very powerful telescope — quite the contrary ; but it should be equatorially mounted, and ought to have a clock motion in the parallel. The image to be impressed on the paper (or collodionized glass) should be formed not in the focus of the object-lens, but in that of the eye-lens, drawn out somewhat beyond the...
