During the last day's march the caravan had kept along one of these rivulets, whose waters, reddened with oxyde of iron, eat away its steep, worn banks. To find it again could not take long, or be very difficult. Evidently they could not descend its impetuous course, but it would be easy to follow it to its junction with a more considerable, possibly a navigable, affluent.
The skeleton appeared to have been burned in a large and very hot fire, which had almost consumed the bones of the deceased. This skeleton was deposited a little to the south of the center of the tumulus; and about 20 feet to the north of it was another, with which were "5th. "6th. A plate of iron which had become an oxyde, but before it was disturbed by the spade resembled a plate of cast iron.
Around the end where the blade had been inserted was a ferule of silver, which, though black, was not much injured by time. Though the handle showed the hole where the blade had been inserted, yet no iron was found, but an oxyde remained of similar shape and size. "4th. Charcoal and wood ashes on which these articles lay, which were surrounded by several bricks very well burnt.
From the infusible, though evaporable, diamond to nitrogen itself, the metallic nature of which has been long suspected by chemists, though still under the mistaken notion of an oxyde, we trace a series of metals from the maximum of coherence to positive fluidity, in all ordinary temperatures, we mean.
"One camera. "One light steel cage, large enough for you to stand in. "One five-pound steel tank, with siphon and hose attachment. "One rifle and ammunition. "Three ounces rosium oxyde. "One ounce chlorate strontium. "You will then, within twenty-four hours, set out with the stenographer and the supplies mentioned and join me in camp on Little Sprite Lake.
Like the others, this one would prescribe the eternal oxyde of zinc and quinine, bromide of potassium and valerian. He had recourse to another thought: "If these remedies have availed me little in the past, could it not be due to the fact that I have not taken the right quantities?" In spite of everything, this expectation of being cured cheered him, but then a new fear entered.
In the case of the Murex brandaris one element only has been found: it is an oxide, which has received the name of oxyde tyrien. No naturalist has as yet discovered what purpose the liquid serves in the economy, or in the preservation, of the animal; it is certainly not exuded, as sepia is by the cuttle-fish, to cloud the water in the neighbourhood, and enable the creature to conceal itself.
This master-piece was still to be solidly applied on a new ground: for that, it was necessary to paste paper over it again, detach it from the temporary gauze which had been put on the impression, add a new coat of oxyde of lead and oil, apply to it a gauze rendered very supple, and on the latter, in like manner done over with a preparation of lead, a raw cloth, woven all in one piece, and impregnated, on its exterior surface, with a resinous substance, which was to confine it to a similar canvass fixed on the stretching-frame.
The small lumps and grains of iron were packed around fit, so as nearly to fill the crucible. A blast of air was to be forced down the pipe so as to rise up among the pieces of granular iron and partially decarburise them. The pipe could then be withdrawn, and the fire urged until the metal with its coat of oxyde was fused, and cast steel thereby produced.
