Seite 155 - They are superior to maps, as they show at a glance the relative heights of the various points, display the geological phenomena, and may be made to delineate the state of cultivation of the districts. The lines of railways, of roads, or of canals, can be more clearly defined upon them, and they are stated to be peculiarly adapted for parish surveys.
Seite 88 - Mr. Bethell found that some solutions were taken up more rapidly by the sap and circulated with it more freely than others. and the pyrolignite of iron seemed to answer best ; he had not hitherto introduced the process in England, because .it was much more expensive than the oil of tar, the pyrolignite costing from 6d.
Seite 80 - ... on to the circumference of the tanks. Notwithstanding the great strength of these girders, several were broken by the pressure applied during the process. The vessels are lined with felt, upon which is laid a covering of...

The upper, or the second, or the third, or even the fourth portion of the ventilating flue might be entirely closed, yet without altering the flame.

The water enters the buckets in the direction of the tangent to the last element of the guide curves, which is a tangent to the first element of the curved buckets. The water ought to press steadily against the curved buckets, entering them without shock or impulse, and quitting them without velocity, in order to obtain the greatest useful effect, otherwise a portion of the water's power must be wasted or expended without producing useful effect...
Seite 180 - Waterloo-bridge, and thence to the top of the tower, where one of the telegraphs was placed; the wire then descended, and a plate of zinc attached to its extremity was plunged into the mud of the river; a similar plate was attached to the extremity at the north side, and was immersed in the water. The circuit was thus completed by the entire breadth of the Thames, and the telegraphs acted as well as if the circuit was entirely metallic.
Seite 60 - ... due to the required velocity of the water reaching the wheel. 3rd. If the level of the water in the reservoir never fall below the mean depth of the reservoir, when at the highest and lowest, and the average depth be between an eighth and a tenth of the height of the fall...
