What we chiefly learn from this writer as to the dyeing process is first, that sometimes the liquid derived from the murex only, sometimes that of the purpura or buccinum only, was applied to the material which it was wished to colour, while the most approved hue was produced by an application of both dyes separately.

They belong, mainly, to the two allied families of the Murex and the Buccinum or Purpura. Eight species of the former, and six of the latter, having their habitat in the Mediterranean, have been distinguished by some naturalists; but two of the former only, and one of the latter, appear to have attracted the attention of the Phoenicians.

By far the greater number of the recent marine species occurring in the several Crag formations are still inhabitants of the British seas; but even these differ considerably in their relative abundance, some of the commonest of the Crag shells being now extremely scarce as, for example, Buccinum Dalei while others, rarely met with in a fossil state, are now very common, as Murex erinaceus and Cardium echinatum.

Joining me, where I was lying upon a flat ledge, peering down into the basin, he presently espied a Triton's trumpet, more than a foot in length, in some five fathoms of water, and pointing it out to Max, he begged him to dive for it, earnestly assuring him that he had never seen so fine a specimen of the "Murex Tritonica."

Gosse himself confesses that it is chiefly as a master of literary form that Browne deserves to be remembered. Why then does he tell us so little about his literary form, and so much about his family, and his religion, and his scientific opinions, and his porridge, and who fished up the murex? Nor is it only owing to its inadequacy that Mr.

Have I passed by the black-tail and the 'thrush', The sea-merle and the shadow of the sea? Best to Corcyra go for cuttlefish, For the acarnè and the fat sea-skull The purple-fish, the little murex too, Mice of the sea and the sea-urchin sweet.

These are books written with gold and silver on vellum stained purple, probably with the now lost murex or fish-dye of the ancients, the tint of which dye-stuff Pliny describes minutely and accurately in his 'Natural History. I need scarcely say that no ordinary flat tint could reproduce this most splendid of colours. I believe it has been noted by Mr.

Here are several species of the genera Murex, Fusus, Buccinum, Mitra, Trochus, and Turbo. Further, there are found here a large Fissurella, and six species of a genus which, from its simple, unwound shell, would be immediately taken for a Patella; the creature, however, closely resembles the Fissurella, with the difference that only one gill is visible in the fissure over the neck.

The rich fisheries of its gulf, the production and manufacture of its excellent wool, and the dyeing of it with the purple juice of the Tarentine -murex-, which rivalled that of Tyre both branches of industry introduced there from Miletus in Asia Minor employed thousands of hands, and added to the carrying trade a traffic of export.

On extraction, it is at first decidedly yellow; then after a little time it becomes green; and, finally, it settles into some shade of violet or purple. Chemical analysis has shown that in the case of the Murex trunculus the liquid is composed of two elementary substances, one being cyanic acid, which is of a blue or azure colour, and the other being purpuric oxide, which is a bright red.
