Philip II. of Spain, the consort of Queen Mary gave a whimsical reason for not eating fish. ‘They are,’ said he, ‘nothing but element congealed, or a jelly of water.’

The broth or jelly of fish, which is usually thrown away, will be found one of the most nourishing animal jellies that can be obtained. It is a pity that those who find it difficult to obtain a sufficiency of nourishing food should not be aware of this, as they might thereby make a second meal of what otherwise yields but one. Supposing a poor family to buy a dinner of plaice, which is a cheap fish—the plaice would be boiled and the meat of the fish eaten, and the liquor and bones of the fish thrown away. Now, let the good housewife put the remains of the fish into the liquor and boil for a couple of hours, and she will find she has something in her pot, which, when strained off, will be as good to her as much of that which is sold in the shops as ‘gelatine.’ This she may use as a simple broth, or she may thicken it with rice, and flavor it with onion and pepper, and have a nourishing and satisfying meal; or, should she have an invalid in her family, one-third of milk added and warmed with it, would be nourishing and restoring.

Dr. Davy, in his Angler and his Friend, tells us, ‘There is much nourishment in fish, little less than in butcher’s meat, weight for weight; and in effect it may be more nourishing, considering how, from its softer fibre, fish is more easily digested. Moreover, there is, I find, in fish—sea-fish—a substance which does not exist in the flesh of land-animals, viz., iodine—a substance which may have a beneficial effect on the health, and tend to prevent scrofulous and tubercular disease, the latter in the form of pulmonary consumption, one of the most cruel and fatal with which civilized society, and the highly educated and refined are afflicted. Comparative trials prove that, in the majority of fish, the proportion of solid matter—that is, the matter which remains after perfect desiccation, or the expulsion of the aqueous part—is little inferior to that of the several kinds of butcher’s meat, game or poultry. And, if we give our attention to classes of people—classed as to quality of food they principally subsist on—we find that the ichthyophagous class are especially strong, healthy, and prolific. In no class than that of fishers do we see larger families, handsomer women, or more robust and active men, or greater exemption from maladies just alluded to.’

In the pastry cooks’ shops of Russia, the tempting morsel offered to Russian appetites is the piroga, an oily fish-cake. Little benches are ranged round tables, on which the favourite dainty is placed, covered over with an oily canvass, for it must be eaten hot. A large pot of green oil and a stand of salt are in readiness, and, as soon as a purchaser demands a piroga, it is withdrawn from its cover, plunged into the oil, sprinkled with salt, and presented dripping to the delighted Muscovite.

‘In some countries, fish, when tainted or even putrid is preferred to that which is fresh. The inhabitants of the banks of the Senegal and Orange rivers pound some small fish of the size of sprats in a wooden mortar, as they are taken from the stream, and afterwards make them up into conical lumps, like our sugar-loaves, which they dry in the sun. In this state, they soon become slightly decomposed, and give out a most unpleasant odour; notwithstanding which, these people consider them a luxury, and eat them dissolved in water, mixed with their kouskoussoo, or dough. Fish, prepared in a somewhat similar manner, is eaten by the Indians on the banks of the Orinoco.[21]

In Beloochistan, the inhabitants feed almost entirely on fish; and their cattle are also fed on dried fish and dates mixed together.

No one who has observed a boiled fish upon the table can have passed unremarked the spinal column with its upward and downward processes, and the four transverse strips of flesh, adjusted alternately in different directions with strong semi-transparent tendons between. The spinous processes, proceeding from the vertebræ upward, support the dorsal fins, whilst the transverse processes downward, with curved bones, encircle partially the bulk of the body. Without being ribs, these latter resemble ribs. Those placed far forward represent the proper thoracic ribs of fishes, but have no direct connexion with the spine. There are other rib-like bones behind. These are abdominal appendages; very numerous in some fishes, such as the herrings, and very few,—and those few conveniently large,—in others, such as the perches and labruses. They are wanting in several of the osseous tribes, such as the Diodons and Tetradons, and are altogether non-existent in the cartilaginous fishes. It is from this fact—that so many of the West Indian fishes belong to the Percoid and Labroid families—that persons are so seldom troubled with what are called by the cook, ‘bony fishes.’—Hence, very little annoyance is experienced from the bones in the fish dishes there.

Very serious consequences have often arisen from eating fish or molluscs, which are poisonous or in an unhealthy state. All Ostraceans, Diodons, and Tetradons, are deleterious, and are to be treated as objectionable, if not absolutely dangerous fishes.

Every one acquainted with the bad reputation of the common mussel (Mytilus edulis) knows also the symptoms produced by the hurtful qualities of it, even when cooked—for it is not generally, like the oyster, eaten raw.

The mussels would seem to owe this injurious quality to feeding on the spawn of the star-fish (Asteria).
