Página 461 - Strata thus loaded with the exuvite of innumerable generations of organic beings afford strong proof of the lapse of long periods of time, wherein the animals from which they have been derived lived and multiplied and died, at the bottom of seas which once occupied the site of our present continents and islands.
Página 143 - The piston thus ascending carries its crown, and consequently the load along with it, and by repeating the operation more water is injected, and the piston continues to ascend till the body comes into contact with the head of the frame B, when the pressure begins ; thus it is manifest that by continuing the process the pressure may be carried to any extent at pleasure ; but we have already stated, in developing the theory, that there are limits beyond which, with a given bore and a given thickness...

To this quotient add from 30 to 100 per cent of itself, — depending on the speed of the pump, — and divide the sum by .7854, and extract the square root of the quotient for the diameter of the steam piston. Example. — What should be the diameter of the 'steam piston to force water against a pressure of 125 pounds per...
