The most important task of the analytical chemist, aside from the acquisition of experimental data, is the coordination and interpretation of such data in terms of the qualitative and quantitative composition of the test substance. As in the old tale of the blind men and the elephant, a single observation or test, not considered in conjunction with others, may lead to entirely erroneous conclusions. On the other hand, mere in crease in the number of such tests, without regard to their need or to their relationship to each other, also may not suffice for drawing the correct inferences from the experimental evidence. The deductive reasoning which is usually associated with the analy tical chemist finds its greatest opportunity for application in the problems of cognition and recognition of carbon compounds. Since a rigid scheme of procedure tends to produce a corresponding rigidity of thought, the intent of the present book is to outline approaches which will minimize the chances of misinterpretation without restricting the analytical chemist in his choice of tests. The selection of subsequent tests or reactions should be governed by the results of the preceding ones rather than by an arbi trary list. The relationships of the various approaches (and the information derived from each) to the composition and constitution of the test sub stance are brought out in the discussion with the hope that they may serve as guide lines for such selection.

This book has been written for the practicing chemist whose occasional task may be qualitative analysis. It deals with the investigation of things as they are without any limitations to the scope. It emphasizes the identification of materials - inorganic, organic, organized (biological), common, rare, described or not described in the accessible literatur- as they actually occur in nature and industry, or are met in the investigation of mishaps and crime. The description of techniques - macro to submicro - and the practice exercises have been included since the teaching of these arts is rarely a part of academic curricula and it happens with increasing frequency that chemists have to acquire them "on the job". In the systematic procedure given, emphasis is placed upon the investiga tion of minute specimens and upon acute reasoning that continuously weighs all accumulating evi9.ence. The work begins with the consideration of the history of the material under investigation. Especially when specks of all organic substance shall be identified, it should be realized that the discovery of the source - and consequently of the possibilities involve- may be the most valuable clue to an efficient solution of the problem.
