Excerpt from General Foundry Practice Tnoss who have had the benefit of a good grounding in Natural Science may pass this chapter over, unless in so far as it may refresh their mommies and perhaps be suggestive of application of their theoretical knowledge to their practical work. It is intended for the beginner, not only to show him the least he must study, if he would attain to the fullest development of scientific method in his present work and in the gradual attainment of his practical experience, but also, incidentally perhaps, to encourage him to begin the work by showing a few of the more obvious applications. In the future, such a chapter may, and most probably will, be unnecessary; but the wide experience of the authors leads them to insert it as at the present desirable for the end they have in view, namely, to attract and help all who are thinkers and workers connected with the foundry.
