Excerpt from The History, Products: And Processes of the Alkali Trade, Including the Most Recent Improvements Passing on to consider more in detail the history of manufactures, we will confine ourselves more especially to those which have chie¿y developed through chemical knowledge being brought to bear upon them and it will not be without interest to take a brief retrospect of the rise and progress in this country of that important branch of manufacture, known as the Alkali Trade, before pausing to study in detail its various ramifications. The study of manufactures during the Middle Ages is attended with the greatest interest, for by it we are enabled to perceive how industry and science go hand in hand. Improvements in manufacturing industries can only arise through the application of new knowledge, which latter can only be attained through the method of experiment. Of such a method the ancients were in want hence, we find, in very early times, when the alchemists evaporated common water, and obtained a residue, that residue was regarded as a product of transformation of the water, a perfectly legitimate conclusion, when we consider that they had no knowledge of the power of certain liquids to dissolve certain substances.
