Page 197 - Were we to press, inferior might on ours; Or in the full creation leave a void, Where, one step broken, the great scale's destroy'd: From Nature's chain whatever link you strike, Tenth, or ten thousandth, breaks the chain alike. And if each system in gradation roll, Alike essential to th' amazing whole, The least confusion but in one, not all "That system only, but the whole must fall.
Page xv - Learn of the mole to plough, the worm to weave; Learn of the little nautilus to sail, Spread the thin oar, and catch the driving gale. Here too all forms of social union find, And hence let Reason, late, instruct mankind: Here subterranean works and cities see ; There towns aerial on the waving tree.

At this time, if the tongue of the horse touches the egg, its operculum is thrown open, and a small active worm is produced, which readily adheres to the moist surface of the tongue, and is from thence conveyed with the food to the stomach.
Page 58 - Africa, that it is scarcely possible to stand upon any open place, such as a rice- plantation or other clear spot, where one or more of these buildings is not to be seen within fifty paces.
