Chaeremonianus the Trallian, when we were at a very noble fish dinner, pointing to a little, long, sharp-headed fish, said the echeneis (ship-stopper) was like that, for he had often seen it as he sailed in the Sicilian sea, and wondered at its strange force; for it stopped the ship when under full sail, till one of the seamen perceived it sticking to the outside of the ship, and took it off. Some laughed at Chaeremonianus for believing such an incredible and unlikely story. Others on this occasion talked very much of antipathies, and produced a thousand instances of such strange effects; for example, the sight of a ram quiets an enraged elephant; a viper lies stock-still, if touched with a beechen leaf; a wild bull grows tame, if bound with the twigs of a fig-tree; and amber draws all light things to it, except basil and such as are dipped in oil; and a loadstone will not draw a piece of iron that is rubbed with onion. Now all these, as to matter of fact, are very evident; but it is hard, if not altogether impossible, to find the cause. Then said I: This is a mere shift and avoiding of the question, rather than a declaration of the cause; but if we please to consider, we shall find a great many accidents that are only consequents of the effect to be unjustly esteemed the causes of it; as for instance, if we should fancy that by the blossoming of the chaste-tree the fruit of the vine is ripened; because this is a common saying,-- The chaste-tree blossoms, and the grapes grow ripe; Or that the little protuberances in the candle-snuff thicken the air and make it cloudy; or the hookedness of the nails is the cause and not an accident consequential to an ulcer. Therefore as those things mentioned are but consequents to the effect, though proceeding from one and the same cause, so one and the same cause stops the ship, and joins the echeneis to it; for the ship continuing dry, not yet made heavy by the moisture soaking into the wood, it is probable that it lightly glides, and as long as it is clean, easily cuts the waves; but when it is thoroughly soaked, when weeds, ooze, and filth stick upon its sides, the stroke of the ship is more obtuse and weak; and the water, coming upon this clammy matter, doth not so easily part from it; and this is the reason why they usually calk their ships. Now it is likely that the echeneis in this case, sticking upon the clammy matter, is not thought an accidental consequent to this cause, but the very cause itself. QUESTION VIII.
