Страница 78 - He had infinite quickness of apprehension, a prodigious memory, and a certain rectifying and methodising power of understanding, which extracted something precious out of all that was presented to it. His stores of miscellaneous knowledge were immense, — and yet less astonishing than the command he had at all times over them.
Страница 127 - The boat was again put in motion. She continued to move on. All were still incredulous. None seemed willing to trust the evidence of their own senses.

Страница 126 - As I had occasion to pass daily to and from the building yard, while my boat was in progress, I have often loitered unknown near the idle groups of strangers, gathering in little circles, and heard various inquiries as to the object of this new vehicle. The language was uniformly that of scorn, or sneer, or ridicule.
Страница 78 - Independently of his great attainments in mechanics, Mr. Watt was an extraordinary, and, in many respects, a wonderful man.
