Présentation de l'éditeur

New Edition of my Course of Qualitative Chemical Analysis having become necessary, within less than two years from the appearance of the last Edition, I have again been guided in making alterations and additions by the experience I have .gained of the working of the book with large Laboratory Classes. The rapid progress made by students who are not afraid of grappling with difficulties, and the sound and thorough analytical knowledge which they are able to acquire, in a much shorter time than formerly, have proved to me, that I have not overtaxed their powers. Nor have I done anything to encourage a belief that a knowledge of Chemical Analysis can be acquired by merely practising mechanically a few tests, without going more fully into the subject. Analysis forms, in my opinion, the key to a sound chemical knowledge. It calls forth more preeminently than any other study, the powers of observation and generalisation. Habits of combination and close mental reasoning have to be cultivated in no mean degree. Being based upon facts, the verification of which experiment places within the reach of every one, any conclusion drawn from actual observation can be speedily put to a practical test. As a means of mental training Chemical A nalysis, if properly practised, cannot fail to take a foremost place in General Education. The methods employed in the present Work have stood the test of many years practice. They are, I believe, well suited to promote accurate and expeditious work. A student who applies himself steadfastly to the study of A nalysis, usually gets through the Course in about six months, and has time left to gain some practice, also, in quantitative Analysis during his first years
