During nine months spent in sailing on the Mediterranean and the Ocean, I have frequently seen many others of the scaly tribe, with forms terrible to the sight; but except middle-sized fishes and sharks, I never saw any of the family of Neptune caught by the sailors. When the sea was smooth, and the air tranquil, we frequently observed dolphins tossing themselves merrily about, and appearing as it were to dance; a spectacle by no means pleasing to us, who had so often found this leaping of dolphins the forerunner, and annunciation of an impending whirlwind and tempest. WHALES. Immense whales were a very terrible, and by no means uncommon sight to us on the ocean, though they never approached the ship. On the desert shores of Brazil we thought we perceived a pirate ship. Fearing some mischance we called for the captain, who from the top of the mast by the help of a telescope discovered it to be an enormous whale. This immense animal, as it tossed itself about on the waves, presented the appearance of a ship. A projecting fin, which is said to be sometimes fifty feet high, had been taken for a mast. From the horrid pipe, or fistula of his head, as from a great fire-engine, he spouted up a vast quantity of water, which, when dispersed by the wind, and shone upon by the rays of the sun, looked white like the sails of a ship. In returning to Europe we observed the water leaping up and breaking itself in an unusual manner, not far from the ship. Imagining that rocks or shoals must be at hand, the captain ordered the prow of the ship to be turned in another direction. But an intolerable stench relieved our minds by discovering the putrid carcass of a very large whale, against which the waters had been dashed. Whales perish in the same way as ships, and die by degrees from being knocked against quicksands and shoals. We sometimes, however, see the carcasses of whales cast on to the shore by the tide. I have spoken elsewhere of melotas, enormous fish, innumerable shoals of which we met during some weeks in the month of November. From the water let us now proceed to the woods and plains of Paraguay, which abound in so many curious plants and trees. PLANTS. The Jesuit priest Thomas Falconer, an Englishman well versed in medicine and botany, frequently and openly declared that Paraguay had been enriched by the bounty of nature with so many wholesome plants, roots, gums, woods and fruits, that whoever was skilled in the knowledge of those things would have no occasion for European druggists to cure any disease. Out of many which Paraguay affords either for medicinal or other purposes, I will describe a few in the order in which they enter my mind. I doubt not that botanists have written on this subject more clearly and methodically; whether more faithfully also, I dare not determine with regard to all. CHINA CHINÆ, OR PERUVIAN BARK.
