This formation is intersected by numerous metalliferous veins, running, though irregularly, N.W. and S.E., and generally at right angles to the many dikes. The veins consist of native silver, of muriate of silver, an amalgam of silver, cobalt, antimony, and arsenic, generally embedded in sulphate of barytes.
The action of the thermo-pile, like that of a voltaic cell, can be reversed. By sending a current through the couple from the antimony to the bismuth we shall find the junction cooled. This "Peltier effect," as it is termed, after its discoverer, has been known to freeze water, but no practical application has been made of it.
It is natural for ignorant people to laugh at the Hibernian who said that he had stolen a pound of chocolate to make tea of. But philosophers are disposed to abstain from the laugh of superiority when they recollect that the Irishman could probably make as good tea from chocolate as the chemist could make butter, sugar, and cream, from antimony, sulphur, and tartar.
The savages put this antimony up in little bags and sold it all over the country to paint their bodies and faces, which made them look like Blackamoors dusted over with silver. Some bags of this they carried away, and also collected a good amount of furs of otters, bears, martens, and minks.
The most interesting feature of all of Basil Valentine's writings that are extant is the distinctive tendency to make his observations of special practical utility. His studies in antimony were made mainly with the idea of showing how that substance might be used in medicine.
His concluding act was to pack two of the empty oil tins with all the valuable lumps of auriferous quartz he could find where he shot the rubbish from the cave beneath the trees. On top of these he placed some antimony ore, and Mir Jan, wondering why the sahib wanted the stuff, carried the consignment to the waiting boat.
The publisher of the English translation of J. I. Hollandus, which is dated 1670, addresses the reader as follows: “Kind reader, the philosophers have written much about their lead, which as Basilus has taught, is prepared from antimony; and I am under the impression that this saturnine work of the present philosopher, Mr.
I thought you said antimony was not very valuable?" "That is not antimony. It is gold. By chance I have hit upon an extremely rich lode of gold. At the most modest computation it is worth hundreds of thousands of pounds. You and I are quite wealthy people, Miss Deane." Iris opened her blue eyes very wide at this intelligence. It took her breath away.
Therefore, touching these five heads, we shall here following treat and so far declare them, as that the general Work may be brought to light and perfected by an intent and studious Operator." This book, though the title might seem to indicate it, is not devoted entirely to the study of antimony, but contains many important additions to the chemistry of the time.
Iron, copper, and arsenical pyrites, antimony, galena, molybdenite, zinc blende, and wolfram were treated in the above manner with similar results. In the above experiments a small chip of wood was employed as the decomposing agent. In one instance I used a piece of leather.
