CHAP. 25.—FISHES WHICH CONCEAL THEMSELVES DURING THE SUMMER; THOSE WHICH ARE INFLUENCED BY THE STARS.
Other fishes,1 again, are unable to bear the heat of summer, and lie concealed during the sixty days of the hottest weather of midsummer; such, for instance, as the glaucus,2 the asellus,3 of the fish generally known by the ancients as the sea-perch; and that there is reason for thinking that it was similar to the Perca scriba of Linnæus, having black lines running across the body. Most naturalists are and the dorade.4 Among the river-fish, the silurus5 is affected by the rising of the Dog-star, and at other times it is always sent to sleep by thunder. The same is also believed to be the case with the sea-fish called cyprinus.6 In addition to this, the whole sea is sensible7 of the rising of this star, a thing which is more especially to be observed in the Bosporus: for there sea-weeds and fish are seen floating on the surface, all of which have been thrown up from the bottom.
