"Manganese" Quotes from Famous Books



... for the Bannatyne Club, where things are going on reasonably well. I hope we may get out some good historical documents in the course of the winter. Dined at the Royal Society Club. At the society had some essays upon the specific weight of the ore of manganese, which was caviare to the President, and I think most of the members. But it seemed extremely accurate, and I have little doubt was intelligible to those who had the requisite key. We supped at Mr. Russell's, where the conversation was as gay ...

... stable, protected from dampness, and subjected to fumigations of sulphurous anhydrid or chlorin gas. The liberation of chlorin gas is brought about by the action of sulphuric acid, either on a mixture of chlorid of sodium and black oxid of manganese or on bleaching powder. Sulphurous anhydrid may be procured by burning sulphur. Some practitioners prescribe small doses of spirits of turpentine in linseed oil. The system requires good support, and the diet should therefore ...

Its supplies of the following are inadequate: antimony, asbestos, kaolin, chromate, corundum, garnet, manganese, emery, nitrates, potash, pumice, tungsten, vanadium, zirconium. Outside of minerals we lack jute, copra, flax fiber, raw silk, tea, coffee, spices, etc. This mere enumeration suggests the absurdity of the "raw materials" argument against the ...

... from the air? Well, there are some very complicated and difficult processes by which we can get it from the air; but we have better processes. There is a substance called the black oxide of manganese: it is a very black-looking mineral, but very useful, and when made red-hot it gives out oxygen. Here is an iron bottle which has had some of this substance put into it, and there is a tube fixed to it, and a fire ready made, and Mr. Anderson will ...
