Стр. 63 - It is a pleasure to stand upon the shore and to see ships tossed upon the sea; a pleasure to stand in the window of a castle and to see a battle and the adventures thereof below: but no pleasure is comparable to the standing upon the vantage ground of truth, (a hill not to be commanded, and where the air is always clear and serene) and to see the errors, and wanderings, and mists, and tempests, in the vale below": so always, that this prospect be with pity, and not with swelling or pride.

[Since the above was in type, we have received a letter from the writer, in which he ingenuously states that he has been informed, since transmitting it, that a tool precisely similar in principle, called the Expanding Centre Bit, is already known to mechanics. As we have no doubt, however, that the present invention was an original one with him, and as it possesses, besides, great merit, we see no occasion for withdrawing the account of it.— EDIT.] STEAM ARTILLERY.
Стр. 407 - Knowledge in general expands the mind, exalts the faculties, refines the taste of pleasure, and opens numerous sources of intellectual enjoyment.
