Page 81 - An admirable and most forcible way to drive up water by fire, not by drawing or sucking it upwards — for that must be, as the philosopher calleth it, intra sphaeram activitatis, which is but at such a distance. But this way hath no bounder, if the vessels be strong enough ; for I have taken a piece of...
Page 82 - ... hours, it burst and made a great crack. So that, having a way to make my vessels so that they are strengthened by the force within them, and the one to fill after the other, I have seen the water run like a constant fountain stream forty feet high.
Page 171 - This uncommon light first attracted the attention of the crews of other vessels. Notwithstanding the wind and tide were adverse to its approach, they saw with astonishment that it was rapidly coming...
Page 214 - ... so injuriously as by the feet of horses in common draught, such carriages will cause less wear of roads than coaches drawn by horses.
Page 83 - ... into the next room ; and with so great ease and geometrical symmetry, that, though it work day and night, from one end of the year to the other, it will not require forty shillings reparation to the whole engine, nor hinder one day's work.
Page 160 - I considered how to produce rotative motions from them in the best manner ; and amongst various schemes which were subjected to trial, or which passed through my mind, none appeared so likely to answer the purpose as the application of the crank in the manner of the common turning-lathe (an invention of great merit, of which the humble inventor, and even its era, are unknown).
Page 171 - She had the most terrific appearance, from other vessels which were navigating the river, when she was making her passage. The first steam-boats, as others yet do, used dry pine wood for fuel, which sends forth a column of ignited vapour many feet above the flue, and whenever the fire is stirred, a galaxy of sparks fly off, and in the night have a very brilliant and beautiful appearance.
Page 162 - My attention was first directed, in the year 1759, to the subject of steam-engines, by the late Dr. Robison, then a student in the University of Glasgow, and nearly of my own age. He at that time threw out an idea of applying the power of the steam-engine to the moving of wheelcarriages, and to other purposes, but the scheme was not matured, and was soon abandoned on his going abroad.

Page 162 - I soon relinquished the idea of constructing an engine upon this principle, from being sensible it would be liable to some of the objections against Savery's engine, viz. the danger of bursting the boiler, and the difficulty of making the joints tight, and also that a great part of the power of the steam would be lost, because no vacuum was formed to assist the descent of the piston.
