Description:Excerpt from Proceedings of the Royal Philosophical Society of Glasgow, 1884 We now take a passing glance at an industry, not perhaps quite so gigantic as the preceding is prospectively, but still of vast importance, and one whose metamorphosis is perhaps quite as complete, and certainly as illustrative of the fact that the appli cation of existing knowledge is frequently as potent a factor in promoting the improvement or development, or it may even be the creation, of a new industry as the discovery of a new principle. 1 refer to the iodine manufacture. For how many long yeala was it known that iodine existed in quantity in the mother-liquors of the nitrate of soda of Peru, during the whole of which time the very reactions upon which its present extraction is based were equally well known. It seems almost incredible that so large a quantity of a substance having so temptingly high a price could have been not only neglected, but absolutely thrown away; but the reason why it was so seems equally incredible. It was simply this - that nobody did anything but talk about it, and contradict each other with regard to the possible production. As soon as ordinary skill was brought to bear upon it, however, it yielded a rich harvest, and proved to the world that there was a practically inexhaustible store of iodine to draw upon, and from an entirely new source. But if nitrate of soda be replaced to a large extent by cheap sulphate of ammonia, will this any longer be a source of iodine? Unquestionably it will, as there will always be a large quantity of nitrate of soda in demand for other than manurial purposes, and, with a restricted output, both nitrate and iodine will bring a more natural price; and the displacement of the former will not only be compensated for, but in all probability we shall see it with a higher market value than sulphate of ammonia - a result which it would be difiicult at present to induce dealers in these articles to believe in.
