Excerpt from Laboratory Notes on Iron and Steel Analyses Royal College of Science, and the Imperial College of Science and Technology, London, further attest their usefulness. In compliance With numerous and repeated requests the notes have been extended and are now published. In their present form it is hoped that they will have an enlarged sphere of useful ness for Metallurgical Students, for Engineers and Foundrymen (who in increasing numbers desire to have an acquaintance with analytical methods), for Iron and Steel Works' Chemists, and for Public Analysts. The general aim of the book has been to set out the complete course of an assay or an analysis in full detail. In many cases whole paragraphs have been reintroduced, where necessary, to obviate the confusion arising from cross references. The analytical methods are given in detail, precise quantities are stated, and the most convenient sizes of beakers, &c., are specified. In these there is no intention of imperiousness. Time and money can be saved by avoiding the waste due to the use of unnecessary excess of chemicals. Good results have been obtained in every-day practice by implicitly following the instructions embodied in the notes. But they must be followed thoughtfully: no book of directions can be a substitute for brains. Examples of calculations are freely given through out the notes, as these have been found to be helpful. The preparation of the necessary solutions is dealt with in a separate part of the book. This arrangement has many advantages.
