Strona ix - I first entered this city, the whole of the machinery was executed by hand. There were neither planing, slotting, nor shaping machines, and, with the exception of very imperfect lathes and a few drills, the preparatory operations of construction were effected entirely by the hands of the workmen.
Strona 152 - The result of this would be a state of universal rest and death, if the universe were finite and left to obey existing laws. But as no limit is known to the extent of matter, science points rather to an endless progress through an endless space of action, involving the transformation of potential energy through palpable motion into heat, than to a single finite mechanism, running down like a clock and stopping forever.
