Catalysis in Industrial Chemistry

knowledge of one generation becomes a part of the technology of the next. Thus the conceptions of chemical dynamics of one decade become translated into the current practice of its successor the doctrines concerning chemical structure and constitution of one period form the basis of large-scale synthetical processes of another an obscure phenomenon like Catalysis is found to be capable of widespread application in manufacturing operations of the most diverse character. This series of Monographs will afford illustrations of these and similar facts, and incidentally indicate their bearing on the trend of industrial chemistry in the near future. They will serve to show how fundamental and essential is the relation of principle to practice They will afford examples of the application of recent know- ledge to modern manufacturing procedure. As regards their scope, it should be stated the books are not intended to cover the whole ground ofthe technology ofthe matters to which they relate. They are not concerned with the technical minuticz of manufacture except in so far as these may be necessary to elucidate some point of principle. In some cases, where the subjects touch the actual frontiers of progress, knowledge is so very recent and its application so very tentative that both are almost certain to ex- perience profound modification sooner or later. This, of course, is inevitable. But even so such books have more than an ephemeral interest. They are valuable as indicating new and only partially occupied territory and as illustrating the vast potentiality of fruitful conceptions and the worth of general principles which have shown themselves capable of useful service.
