Half a century has scarcely elapsed since a _manufactured_ Mermaid was shown in London with all the confidence of its being a natural creature. In the winter of 1822 there was exhibited at the Egyptian Hall, in Piccadilly, this pretended Mermaid, which was visited by from 300 to 400 persons daily! The imposture, however, was too gross to last long; and it was ascertained to be the dried skin of the head and shoulders of a monkey attached very neatly to the dried skin of a fish of the salmon kind with the head cut off; the compound figure being stuffed and highly varnished, the better to deceive the eye. This grotesque object was taken by a Dutch vessel from on board a native Malacca boat; and from the reverence shown to it by the sailors it is supposed to have represented the incarnation of one of the idol gods of the Malacca Islands. A correspondent of the "Magazine of Natural History," 1829, however, avers that the above "Mermaid" was brought from the East Indies; for being at St. Helena in 1813 he saw it on board the ship which was bringing it to England. The impression on his mind was that it was an artificial compound of the upper part of a small ape with the lower half of a fish; and by aid of a powerful glass he ascertained the point of union between the two parts. He was somewhat staggered to find that this was so neatly effected that the precise line of junction was not satisfactorily apparent: the creature was then in its best state of preservation. In a volume of "Manners and Customs of the Japanese," published in 1841, we, however, find the following version of the history of the above Mermaid:--"A Japanese fisherman seems to have displayed ingenuity for the mere purpose of making money by his countrymen's passion for everything odd and strange. He contrived to unite the upper half of a monkey to the lower half of a fish so neatly as to defy ordinary inspection. He then gave out that he had caught the creature in his net, but that it had died shortly after being taken out of the water; and he derived considerable pecuniary profit from his cunning in more ways than one. The exhibition of the sea monster to Japanese curiosity paid well; yet more productive was the assertion that the half-human fish, having spoken during the five minutes it existed out of its native element, had predicted a certain number of years of wonderful fertility and a fatal epidemic, the only remedy for which would be the possession of the marine prophet's likeness! The sale of these _pictured Mermaids_ was immense. Either the composite animal, or another, the offspring of the success of the first, was sold to the Dutch factory and transmitted to Batavia, where it fell into the hands of a speculating American, who brought it to Europe; and here, in the year 1822-3, exhibited his purchase as a real Mermaid to the admiration of the ignorant, the perplexity of the learned, and the filling of his own purse."
