Excerpt from Exercises in Quantitative: Chemical Analysis, With a Short Treatise on Gas Analysis A preliminary edition of this book, as many of my friends are aware, was issued a little over a year ago for the benefit of chiefly my own students. That edition, however, was little more than a reproduction of what had long had currency in my laboratory as a trypographed book. Hence this volume may be introduced as having already been used - and I hope not without success - in a largely-attended teaching laboratory for a series of years. However it may stand with analysis generally, quantitative analysis can be taught only by examples; and in the earlier stages of the course the technicalities of the subject are the principal things to be taught. Hence our exercises on "analytical methods" (section 2) are arranged, not according to any scientific system, but so that, at any given point of his progress, the student has become familiar with as many different operations as could have been learned during the time. To some of my readers the tone of the earlier exercises more especially may savour a little of mechanical drilling. Why tell the student so minutely what he has to do and hinder him from exercising his own ingenuity? Some ten years ago, if a book like the present had been placed before me, I should have asked this question myself. But I have since come to modify my views. The technicalities of quantitative analysis are the very things which the student is not likely to find out by himself. He had better be drilled into doing them correctly. What is the good, for instance, of letting him spoil a series of ammonia determinations by mismanaging his chloro-platinate precipitates? It surely is better to show him quite directly what he has to do; and if it is, why should not the book tell him, and thus save the time of the teacher? No fear of any talented student being spoiled by a course of judicious drilling. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
