Across the streak of the rocks, colored by beautiful green tints, wound metallic threads of copper, of manganese, with traces of platinum and gold. I could not help gazing at these riches buried in the entrails of Mother Earth, and of which no man would have the enjoyment to the end of time!
The thimble, l, is surrounded by an envelope, q, of platinum wire netting or other refractory material of the same form. The gaseous mixture arriving by the pipe, i, escapes at the upper orifices, r, and passes down against the interior surface of the cone, o, out at the orifices, p, and escapes through the orifices in the cap, l, at which it is burned.
In later life Edison has been more circumspect, but throughout his early career he was constantly getting into some kind of scrape. Besides, he was obliged to raise additional large sums of money from other sources for this purpose. "In the early days I was experimenting with metallic filaments for the incandescent light, and sent a certain man out to California in search of platinum.
Consider the varied and diversified applications of platinum, which has owed its existence as a useful metal entirely to the labours of an illustrious chemical philosopher; look at the beautiful yellow afforded by one of the new metals, chrome; consider the medical effects of iodine in some of the most painful and disgusting maladies belonging to human nature, and remember how short a time investigations have been made for applying the new substances.

The casket was of sweet-scented wood, and the initials J. C. were inlaid upon the lid in gold and platinum. J. C., Justin Cornelies so, it had belonged to my father.
It isn't like when we went for the city of gold. There we had to look for a certain ruined temple, which was the landmark. When we went after the platinum in Siberia we had to look for the place of the high winds, so I could use my air glider. But now we're trying to locate a man who traveled on foot through the jungles, and if we went in an airship we might just miss the connecting link."
