Síđa 543 - They now are seen to resemble a luxuriant garden, which contains the greatest variety of productions, in different nourishing beds; and one advantage we may at least reap from it is, that we can, as it were, extend the range of our experience to an immense duration.
Síđa 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 cones of light are made to coincide by a double-image prism, the extra images being cut off by an eye-stop. The star to be measured is thus seen in the same field with the pole star, with the same aperture and magnifying power.
Síđa 485 - Such a vessel filled with any number of perfect liquids, would be emptied in the same time — whatever their specific gravity. As at any given horizon, inertia is directly proportional to gravity, the heavier the liquid the greater would be the power required to move it; but the motive power would be in proportion to the pressure, or in other words to the weight, and therefore all perfect liquids should issue from the same orifice with the same velocity. To test this proposition, eight fluid ounces...

Statistics of industry and trade must be secured for the use of Congress in making treaties or imposing tariffs, to show to producers the best markets,...
