BOOK XXXII.[1] REMEDIES DERIVED FROM AQUATIC ANIMALS. CHAP. 1. (1.)—THE POWER OF NATURE AS MANIFESTED IN ANTIPATHIES. THE ECHENEÏS: TWO REMEDIES. Following the proper order of things, we have now arrived at the culminating point of the wonders manifested to us by the operations of Nature. And even at the very outset, we find spontaneously presented to us an incomparable illustration of her mysterious powers: so much so, in fact, that beyond it we feel ourselves bound to forbear extending our enquiries, there being nothing to be found either equal or analogous to an element in which Nature quite triumphs over herself, and that, too, in such numberless ways. For what is there more unruly than the sea, with its winds, its tornadoes, and its tempests? And yet in what department of her works has Nature been more seconded by the ingenuity of man, than in this, by his inventions of sails and of oars? In addition to this, we are struck with the ineffable might displayed by the Ocean’s tides, as they constantly ebb and flow, and so regulate the currents of the sea as though they were the waters of one vast river.
