Tyrian Purple.
The purple dye of Tyre was discovered about fifteen centuries before the Christian era, and the art of using it did not become lost until the eleventh century after Christ. It was obtained from two genera of one species of shell-fish, the smaller of which was called buccinum, the larger purpura, and to both the common name mure was applied. The dye-stuff was procured by puncturing a vessel in the throat of the larger genus, and by pounding the smaller entire. The tints capable of being imparted by this material were various—representing numerous shades between purple and crimson, but the imperial tint was that resembling coagulated blood. That it was known to the Egyptians, in the time of Moses, is sufficiently obvious from the testimony of more than one Scriptural passage. Ultimately, in later ages, a restrictive policy of the eastern emperors caused the art to be practised by only a few individuals, and at last, about the commencement of the twelfth century, when Byzantium was suffering from attacks without and dissensions within, the secret of imparting the purple dye of Tyre was lost.
The rediscovery of Tyrian purple, as it occurred in England, was made by Mr. Cole, of Bristol. About the latter end of the year 1683, this gentleman heard from two ladies residing at Minehead, that a person living somewhere on the coast of Ireland supported himself by marking with a delicate crimson color the fine linen of ladies and gentlemen sent him for that purpose, which color was the product of a shell-fish. This recital at once brought to the recollection of Mr. Cole the tradition of Tyrian purple. He, without delay, went in search of the shell-fish, and, after trying various kinds without success, his efforts were at length successful. He found considerable quantities of the buccinum on the sea-coast of Somersetshire and the opposite coast of South Wales. The fish being found, the next difficulty was to extract the dye, which in its natural state is not purple but white, the purple being the result of exposure to the air. At length our acute investigator found the dye-stuff in a white vein lying transversely in a little furrow or cleft next to the head of the fish.
Odor of Patchouli.
The odor of patchouli was known in Europe before the material itself was introduced, in consequence of its use in cashmere to scent the shawls with a view of keeping out moths, which are averse to it; hence the genuine cashmere shawls were known by their scent, until the French found out the secret and imported the herb for use in the same way.
Veneered Diamonds.
Quite a notable industry is carried on in Paris, namely, the manufacture of what are termed veneered diamonds. The body of the gem is of quartz or crystal. After being cut into a proper shape, it is put into a galvanic battery, which coats it with a liquid, the latter being made of diamonds which are too small to be cut and of the clippings taken from diamonds during the process of shapening them. In this way all the small particles of diamonds that heretofore have been regarded as comparatively worthless, can, by means of this ingenious process, be made of service to the jeweler.
Hungary Water.
This is a spirit of wine distilled upon rosemary, and contains a powerful aroma of the plant. For many years it was mainly manufactured at Beaucaire and Montpellier, in France, where the plant grows in abundance. The name seems to signify that this water, so celebrated for its medicinal virtues, is an Hungarian invention; and we read in various books that the recipe for preparing it was given to a queen of Hungary by a hermit, or, as others say, by an angel, who appeared to her in a garden, all entrance to which was shut, in the form of a hermit or youth. Others affirm that Elizabeth, wife of Charles Robert, king of Hungary, who died in 1380, was the inventor. By often washing with this spirit of rosemary, when in the seventieth year of her age, she was cured, as we are told, of the gout and an universal lameness; so that she not only lived to pass eighty, but became so lively and beautiful that she was courted by the king of Poland, who was then a widower, and who wished to make her his second wife. Hoyer says that the recipe for preparing this water, written by Queen Elizabeth's own hand, in golden characters, is still preserved in the Imperial Library at Vienna. Beckmann says such is not the case.
