Halaman 209 - The photometer consists of a horizontal telescope pointing to the west, and having two objectives. By means of two prisms mounted in front of the telescope, the pole star is reflected into one object-glass, and the star to be measured into the other.

The star to be measured is thus seen in the same field with the pole star, with the same aperture and magnifying power.
Halaman 485 - Such a vessel filled with any number of perfect liquids, would be emptied in the same time — whatever their specific gravity.

To test this proposition, eight fluid ounces...
