Страница 174 - By his admirable contrivances it has become a thing stupendous alike for its force and its flexibility, for the prodigious power which it can exert, and the ease and precision and ductility with which it can be varied, distributed, and applied. The trunk of an elephant, that can pick up a pin, or rend an oak, is as nothing to it.
