Page 6 - When he made a decree for the rain, and a way for the lightning of the thunder : Then did he see it, and declare it ; he prepared it, yea and searched it out. And unto man he said, Behold the fear of the Lord, that is wisdom ; and to depart from evil is understanding.
Page 7 - Now it happened that a man from Dartmouth, named Thomas Newcomen, without any knowledge whatever of the speculations of Captain Savery, had at the same time also made up his mind, in conjunction with his assistant, a plumber by the name of Galley, to invent a fire-machine for drawing water from the mines.
Page 8 - Q feet long, Mr. Ridley induced the inventors to concede me a grant to construct fire-machines, and as the young Mr. Calley was subsequently initiated by me into the theory, we both formed a company together and signed a contract to the effect that we should divide equally between us all the income we might derive from the construction and supervision of fireengines, which contract still holds good whenever I like to return to England.
Page 8 - ... the steam which the inventors harboured in their minds, thinking that the steam rises from or is generated by the boiling water in proportion to the quantities of water. In consequence of these false principles they made their boilers very high, as can easily be seen from the Stafford machine, the boiler of which they made of greater height than width, thus not knowing that they should give the boiler a suitable shape. Neither did they then possess the knowledge of the great importance of letting...
Page 22 - Triewald, for instance, in 1734, believed that steam was "nothing but moist air, heated to a high degree, every particle of air being surrounded by an incomparably thin membrane or coat of water, very much like a bladder".
Page x - presented mankind with one of the most wonderful inventions that has ever been brought into the light of day, and this by means of ignorant folk who had never acquired a certificate at any University or Academy.
Page 59 - Prior found out and invented a certain Machine or Engine which by the power of the Atmosphere will effectually draw the Water out of all Mines and Collieries at a very small...

Page 16 - ... same way as other fluid matter does, and this in proportion to the vertical height and base. Consequently it will be found that the power of the fire-machine varies with the diameter or piston-area of the cylinder, and is in every way equal to the weight of a column or pillar of mercury, which has a base equal to the area of the piston and a height of 29 inches, which again is equal to a watercolumn with the same base and a height of 34 feet, because mercury is 14 times heavier than water.
Page xi - ... undertake the project on the grounds that so large a cylinder could not be supplied with sufficient steam. Commenting on this refusal, Triewald writes: The cause of this conclusion was the false principles concerning the steam which the inventors harboured in their minds, thinking that the steam rises from or is generated by the boiling water in proportion to the quantities of water. In consequence of these false principles they made their boilers very high, as can easily be seen from the Stafford...
