CHAPTER VIII.

FISH. [_Nothing is more difficult than to give the average prices of Fish, inasmuch as a few hours of bad weather at sea will, in the space of one day, cause such a difference in its supply, that the same fish--a turbot for instance--which may be bought to-day for six or seven shillings, will, to-morrow, be, in the London markets, worth, perhaps, almost as many pounds. The average costs, therefore, which will be found appended to each recipe, must be understood as about the average price for the different kinds of fish, when the market is supplied upon an average, and when the various sorts are of an average size and quality._ GENERAL RULE IN CHOOSING FISH.--_A proof of freshness and goodness in most fishes, is their being covered with scales; for, if deficient in this respect, it is a sign of their being stale, or having been ill-used._] FRIED ANCHOVIES.
