FISH. by themselves, nor in large shoals, are the most digestible, such as the congers, and the carchariæ, and fish of that kind. But the gregarious kinds of fish of that sort are very pleasant to the palate, for they are fat; but they are heavy, and difficult of digestion, on which account they are very good for curing; and, indeed, these kinds make the best cured fish of all; they are also very good roasted, for by that process their fatty parts are got rid of. But those kinds which are skinned before they are dressed, as a general rule, are those fish which have a rough outside to their skin, not of scales, but such as rays and rhinæ have. And all these kinds are easily divided into small pieces, but they have not a sweet smell. And they supply the body with plenty of moist nourishment, and of all boiled fish they have the greatest effect on the bowels; but when they are roasted they are not so good. And the whole class of molluscous fish, such as polypi and cuttlefish, and others like them, are very indigestible, on which account they are very serviceable in exciting the amatory passions. They are also calculated to cause flatulence; and the time of indulgence in amatory pleasures requires a flatulent habit of body. All these fish are better when boiled. For their juices are injurious, and you may see what juices they emit when they are washed; and the boiling extracts all these juices from their flesh. For as the heat which is applied in boiling is a gradual one, and conjoined with moisture, there is, as it were, a sort of washing of them. But when they are roasted, that dries up the moisture, and moreover, as their flesh is hard by nature, it is natural that it should be made more so in this way.
55. "But anchovies of all kinds, and membrades, and trichides, and all the other little fish which we eat backbones and all, make the digestion flatulent, and give a good deal of moist nutriment. And so, as the digestion is unequal, the flesh being digested with great rapidity, and the bones dissolving slowly, for the anchovies are very bony of themselves, the digestion of the one part hinders the digestion of the other, and so flatulence arises from the digestion, and moisture comes from the quantity of nourishment. They are better when they are boiled, but still they have very unequal effects on the bowels. The fish which keep close to the rocks, such as tench, and scorpions, and sea-sparrows, and others of the same kind, supply a dry kind of nourishment to our bodies, but
