Tales of "Wonderful Fish" are common in the works of the old naturalists, whence they are quoted from generation to generation. Sir John Richardson has lately demolished one queer fish, which was as certain to reappear whenever opportunity offered, as the elephant pricked with the tailor's needle does in books of stories of the animal world. We allude to that monstrous myth, the great Manheim Pike, with a collar round his neck, put into a lake by the Emperor Frederick II. in the year 1230; and taken out in the 276th year of his age, the 17th foot of his length, and the 350th pound of his weight. M. Valenciennes, a naturalist of repute, has entered into a critical history of this monster, and has found him to be apocryphal. The creature was, at any rate, taken in several places at once, the legends written on his brass collar do not agree, and his alleged skeleton has been found to be made up of various bones of various fishes; while the vertebræ are, unfortunately, so many, that Professor Owen would order him out of Court in an instant as a rank impostor. Probably some specimen of the _Mecho_, the monstrous fish of the Danube--which has even now been scarcely described, and which has only recently been identified as one of the salmon tribe--having been called a pike, may be at the bottom of the legend of the great Manheim fish. But Sir John Richardson produces another big pike, killed by an intrepid "angler seventy years of age, with a single rod and bait"--an observation which leads to the inquiry of the possibility of catching a single fish with more than one rod and bait--"that weighed seventy-eight pounds." This is stated to have happened in the county of Clare; the angler's name was O'Flanagan. Here is another wonderful story:--The Bohemians have a proverb--"Every fish has another for prey:" that named the Wels has them all. This is the largest fresh-water fish found in the rivers of Europe, except the sturgeon; it often reaches five or six feet in length. It destroys many aquatic birds, and we are assured that it does not spare the human species. On the 3d of July, 1700, a peasant took one near Thorn, that had an infant entire in its stomach! They tell in Hungary of children and young girls being devoured on going to draw water; and they even relate that, on the frontiers of Turkey, a poor fisherman took one that had in its stomach the body of a woman, her purse full of gold, and a _ring_! The fish is even reported to have been taken sixteen feet long. The old stories of rings found in the stomachs of fishes will be remembered; as well as here and there a _book_ found in the stomach of a fish!
