Page 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.
Page 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...
Page 340 - The square of the hypothenuse is equal to the sum of the squares of the other two sides ; as, 5033 402+302.
Page 129 - ... inch ; and divide the product by the pressure of steam in pounds per square inch. The quotient will give the area of steam piston in square inches to balance the resistance. 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...
Page 458 - Mack-clay, is actual LAVA, and flowed from a volcano whose funnel, or shaft, did not approach the open air, but disgorged its fiery contents between the strata in all directions.
Page xxxvii - ... piled together ; between these balls smaller shot may be placed, and between these, others still smaller, or gravel, or sand, may be diffused. In a similar manner, a certain quantity of particles of sugar- can be taken up in water without increasing the bulk; and when the water has dissolved the sugar, salt may be dissolved in it, and yet the bulk remain the same ; and admitting that the particles of water are round, this is easily accounted fos.
Page 242 - ... the adulterate metal will rise, and the pure descend. " The reason is, all bodies lose some of their weight in a fluid, and the weight which a body loses in a fluid, is to its whole weight, as the specific gravity of the fluid is to that of the body. The...
Page 226 - This ball is connected with a lever acting upon some part of the machinery, which controls the power or regulates the amount of resistance, as already explained in the case of the governor. When the level of the water rises, the buoyancy of the ball causes it...
