to time collected on the refuse of the ore, and found in some places half an ell thick. This substance, which is saltish, is formed into a lye, and boiled in small leaden pans. The rest of the process I do not know, but I observed that it crystallizes like saltpetre, but is stronger and whiter. It is also cast into small cakes about the thickness of one’s hand. This vitriol is employed by the leather-dressers, and may be used for many things instead of alum; but it cannot be used in dressing white skins, because it makes them yellowish.”

Paracelsi Opera. Strasb. 1616, fol. I shall here transcribe the principal passage. Of zinc: – There is another metal, zinc, which is in general unknown. It is a distinct metal of a different origin, though adulterated with many other metals. It can be melted, for it consists of three fluid principles, but it is not malleable. In its colour it is unlike all others, and does not grow in the same manner; but with its ultima materia I am as yet unacquainted, for it is almost as strange in its properties as argentum vivum. It admits of no mixture, will not bear the fabricationes of other metals, but keeps itself entirely to itself.

How much duke Julius, who in other respects did great service to his country, suffered himself to be duped by the art of making gold, appears from an anecdote given by Rehtmeier, p. 1016. Of this anecdote I received from M. Ribbentrop an old account in manuscript, which one cannot read without astonishment. There is still shown, at the castle of Wolfenbuttle, an iron stool, on which the impostor, Anna Maria Zieglerinn, named Schluter Ilsche, was burnt, February 5, 1575.

Page 83: – “When the people at the melting-houses are employed in melting, there is formed under the furnace, in the crevices of the wall, among the stones where it is not well plastered, a metal which is called zinc or conterfeht; and when the wall is scraped, the metal falls down into a trough placed to receive it. This metal has a great resemblance to tin, but it is harder and less malleable, and rings like a small bell. It could be made also, if people would give themselves the trouble; but it is not much valued, and the servants and workmen only collect it when they are promised drink-money. They however scrape off more of it at one time than at another; for sometimes they collect two pounds, but at others not above two ounces. This metal, by itself, is of no use, as, like bismuth, it is not malleable; but when mixed with tin, it renders it harder and more beautiful, like the English tin. This zinc or bismuth is in great request among the alchemists.”

Pott refers to Lawson’s Dissert. de Nihilo, and quotes some words from it; but I cannot find it; nor am I surprised at this, as it was not known to Dr. Watson. – See Chemical Essays, iv. p. 34. Pryce, in Mineral. Cornub., p. 49, says, “The late Dr. J. Lawson, observing that the flowers of lapis calaminaris were the same as those of zinc, and that its effects on copper were also the same with that semi-metal, never remitted his endeavours till he found the method of separating pure zinc from that ore.” The same account is given in the supplement to Chambers’s Dictionary, 1753, art. calm. and zinc; and in Campbell’s Political Survey of Britain, ii. p. 35. The latter however adds, that Lawson died too early to derive any benefit from his discovery.

Raynal says that the company purchase it at the rate of twenty-eight florins three-quarters per hundred weight, and that this price is moderate. At Amsterdam, however, the price was commonly from seventeen to eighteen florins banco. According to a catalogue which I have in my possession, the price, on the 9th of May, 1788, was seventeen florins, and on the 22nd of January, 1781, it was only sixteen.

Matthesius, Pred. v. p. 250. – “Conterfeil is a metal of little value, formed by additions and colouring substances, so that it resembles gold or silver, as an image, or anything counterfeited, does its archetype. Thus copper is coloured by calamine and other mixtures, in such a manner that it appears to be pure gold.” In the police ordinance issued at Strasburg in 1628, young women are forbidden to wear gold or silver, or any conterfaite, and everything that might have the appearance of gold or silver.

This fish was a first-rate article of luxury among the Romans, and was purchased at a dear rate. Juvenal says, “Mullum sex millibus emit, æquantem sane paribus sestertia libris.” See Plin. lib. ix. c. 17. The Italians have a proverb, “La triglia non mangia chi la piglia,” which implies, that he who catches a mullet is a fool if he eats it and does not sell it. When this fish is dying, it changes its colours in a very singular manner till it is entirely lifeless. This spectacle was so gratifying to the Romans, that they used to show the fish dying in a glass vessel to their guests before dinner.

A great service would be rendered to the natural history of the ancients, if some able systematic naturalist would collect all the Greek names used at present. Tournefort and others made a beginning.

See Anderson’s Hist. of Commerce, and Pennant’s Zoology, p. 300. Both these authors refer to Fuller’s British Worthies. [The carp existed in England before the year 1486: for in Dame Juliana Berners’ work on Angling, which was published at St. Albans (hence called the Book of St. Albans) in 1486, we find the following passage: speaking of the carp, she says “That it is a deyntous fysshe, but there ben but few in Englonde. And therefore I wryte the lesse of hym. He is an euyll fysshe to take. For he is so stronge enarmyd in the mouthe, that there
