It was, as I have said, almost that of a sphinx, a dusky-hued sphinx, as though the matter which composed it had been oxidized by the inclemency of the polar climate. And then a possibility flashed into my mind, an hypothesis which explained these astonishing phenomena. “Ah!” I exclaimed, “a loadstone! that is it! A magnet with prodigious power of attraction!”
"I haven't bought my winter things yet," said Matilda; "it was so mild, that I thought I'd wait till I could afford it better. But I've chosen the very thing I mean to buy. You know Mrs. Twilling's, at the top of the Row, the corner shop? Well, in the window there's a perfectly lovely long cloak, all lined with squirrel's fur, and with those nice oxidized silver fastenings.
Shelves of oxidized metal will be found smooth enough to prevent any abrasion of bindings. Shelves should be easily adjustable to any height, to accommodate the various sizes of books. In calculating shelf capacity, one and a half inches thickness a volume is a fair average, so that each hundred volumes would require about thirteen feet of linear shelf measurement.
On and on it moved, its little pinkish feet pattering almost silently on the oxidized metal surface of the rail. Its sensitive ears picked up the movements and the squeals of other rats, but it paid them no heed. Several times, it met other rats on the rail, but most of them sensed the alienness of this rat and scuttled out of its way. Once, it met a rat who did not give way.
I shut my eyes and pulled, but the nitric acid splashed all over my face and ran down my back. I rushed to a sink, which was only half big enough, and got in as well as I could and wiggled around for several minutes to permit the water to dilute the acid and stop the pain. My face and back were streaked with yellow; the skin was thoroughly oxidized.
A drop of the oxidized solution should be tested on a watch-glass with potassium ferricyanide, to insure a complete oxidation. The ionic changes which are involved in this oxidation are perhaps most simply expressed by the equation Even with this precaution the entire absence of sulphates from the first iron precipitate is not assured.
He frowned deeply after the first involuntary heart-throb. With the stick he cleared away the undergrowth, and revealed the skeleton of a man. The bones were big and strong, but oxidized by the action of the air. Jenks had injured the left tibia by his tread, but three fractured ribs and a smashed shoulder-blade told some terrible unwritten story.
In a second experiment with well water a similar result was obtained; more organic matter was oxidized when the organisms had been killed by the addition of sulphuric acid than when the original water was allowed to stand for an equal length of time. The author also discusses the statement made by Dr.
Fat and starch may be oxidized in a chemist's test tubes, and will there liberate energy; but they do not, under these conditions, manifest vital phenomena. Proteid may be brought in contact with oxygen without any oxidation occurring, and even if it is oxidized no motion or assimilation or reproduction occurs under ordinary conditions.
Some groups of trees, some green hedges and the roofs of various farms broke the monotony of the countryside. The fields were covered with stubble from the recent harvest. The haycocks dotted the ground with their yellowish cones, now beginning to darken and take on a tone of oxidized gold. In the valleys the birds were flitting about, shaking off the dew of dawn.
