OYSTER SOUP.
I.
196. INGREDIENTS.—6 dozen of oysters, 2 quarts of white stock,½ pint of cream, 2 oz. of butter, 1–½ oz. of flour; salt, cayenne, and mace to taste.
Mode.—Scald the oysters in their own liquor; take them out, beard them, and put them in a tureen. Take a pint of the stock, put in the beards and the liquor, which must be carefully strained, and simmer for ½ an hour. Take it off the fire, strain it again, and add the remainder of the stock with the seasoning and mace. Bring it to a boil, add the thickening of butter and flour, simmer for 5 minutes, stir in the boiling cream, pour it over the oysters, and serve.
Time.—1 hour. Average cost, 2s. 8d. per quart.
Seasonable from September to April.
Sufficient for 8 persons.
Note.—This soup can be made less rich by using milk instead of cream, and thickening with arrowroot instead of butter and flour.
II.
197. INGREDIENTS.—2 quarts of good mutton broth, 6 dozen oysters, 2 oz. butter, 1 oz. of flour.
Mode.—Beard the oysters, and scald them in their own liquor; then add it, well strained, to the broth; thicken with the butter and flour, and simmer for ¼ of an hour. Put in the oysters, stir well, but do not let it boil, and serve very hot.
Time.—¾ hour. Average cost, 2s. per quart.
Seasonable from September to April.
Sufficient for 8 persons.
SEASON OF OYSTERS.—From April and May to the end of July, oysters are said to be sick; but by the end of August they become healthy, having recovered from the effects of spawning. When they are not in season, the males have a black, and the females a milky substance in the gill. From some lines of Oppian, it would appear that the ancients were ignorant that the oyster is generally found adhering to rocks. The starfish is one of the most deadly enemies of these bivalves. The poet says:—
The prickly star creeps on with full deceit
To force the oyster from his close retreat.
When gaping lids their widen'd void display,
The watchful star thrusts in a pointed ray,
Of all its treasures spoils the rifled case,
And empty shells the sandy hillock grace.
PRAWN SOUP.
198. INGREDIENTS.—2 quarts of fish stock or water, 2 pints of prawns, the crumbs of a French roll, anchovy sauce or mushroom ketchup to taste, 1 blade of mace, 1 pint of vinegar, a little lemon-juice.
Mode.—Pick out the tails of the prawns, put the bodies in a stewpan with 1 blade of mace,½ pint of vinegar, and the same quantity of water; stew them for ¼ hour, and strain off the liquor. Put the fish stock or water into a stewpan; add the strained liquor, pound the prawns with the crumb of a roll moistened with a little of the soup, rub them through a tammy, and mix them by degrees with the soup; add ketchup or anchovy sauce to taste, with a little lemon-juice. When it is well cooked, put in a few picked prawns; let them get thoroughly hot, and serve. If not thick enough, put in a little butter and flour.
Time.—hour. Average cost, 1s. 1d. per quart, if made with water.
Seasonable at any time. Sufficient for 8 persons.
Note.—This can be thickened with tomatoes, and vermicelli served in it, which makes it a very tasteful soup.

THE PRAWN.—This little fish bears a striking resemblance to the shrimp, but is neither so common nor so small. It is to be found on most of the sandy shores of Europe. The Isle of Wight is famous for shrimps, where they are potted; but both the prawns and the shrimps vended in London, are too much salted for the excellence of their natural flavour to be preserved. They are extremely lively little animals, as seen in their native retreats.

CHAPTER VII.
THE NATURAL HISTORY OF FISHES.
199. IN NATURAL HISTORY, FISHES form the fourth class in the system of Linnaeus, and are described as having long under-jaws, eggs without white, organs of sense, fins for supporters, bodies covered with concave scales, gills to supply the place of lungs for respiration, and water for the natural element of their existence. Had mankind no other knowledge of animals than of such as inhabit the land and breathe their own atmosphere, they would listen with incredulous wonder, if told that there were other kinds of beings which existed only in the waters, and which would die almost as soon as they were taken from them. However strongly these facts might be attested, they would hardly believe them, without the operation of their own senses, as they would recollect the effect produced on their own bodies when immersed in water, and the impossibility of their sustaining life in it for any lengthened period of time. Experience, however, has taught them, that the "great deep" is crowded with inhabitants of various sizes, and of vastly different constructions, with modes of life entirely distinct from those which belong to the animals of the land, and with peculiarities of design, equally wonderful with those of any other works which have come from the hand of the Creator. The history of these races, however, must remain for ever, more or less, in a state of darkness, since the depths in which they live, are beyond the power of human exploration, and since the illimitable expansion of their domain places them almost entirely out of the reach of human accessibility.
200. IN STUDYING THE CONFORMATION OF FISHES, we naturally conclude that they are, in every respect, well adapted to the element in which they have their existence. Their shape has a striking resemblance to the lower part of a ship; and there is no doubt that the form of the fish originally suggested the form of the ship. The body is in general slender, gradually diminishing towards each of its extremities, and flattened on each of its sides. This is precisely the form of the lower part of the hull of a ship; and it enables both the animal and the vessel, with comparative ease, to penetrate and divide the resisting medium for which they have been adapted. The velocity of a ship, however, in sailing before the wind, is by no means to be compared to that of a fish. It is well known that the largest fishes will, with the greatest ease, overtake a ship in full sail, play round it without effort, and shoot ahead of it at pleasure. This arises from their great flexibility, which, to compete with mocks the labours of art, and enables them to migrate thousands of miles in a season, without the slightest indications of languor or fatigue.
201. THE PRINCIPAL INSTRUMENTS EMPLOYED BY FISHES to accelerate their motion, are their air-bladder, fins, and tail. By means of the air-bladder they enlarge or diminish the specific gravity of their bodies. When they wish to sink, they compress the muscles of the abdomen, and eject the air contained in it; by which, their weight, compared with that of the water, is increased, and they consequently descend. On the other hand, when they wish to rise, they relax the compression of the abdominal muscles, when the air-bladder fills and distends, and the body immediately ascends to the surface. How simply, yet how wonderfully, has the Supreme Being adapted certain means to the attainment of certain ends! Those fishes which are destitute of the air-bladder are heavy in the water, and have no great "alacrity" in rising. The larger proportion of them remain at the bottom, unless they are so formed as to be able to strike their native element downwards with sufficient force to enable them to ascend. When the air-bladder of a fish is burst, its power of ascending to the surface has for ever passed away. From a knowledge of this fact, the fishermen of cod are enabled to preserve them alive for a considerable time in their well-boats. The means
