In the June "Report for Analytical Chemists," we requested viewpoints from readers on the Fisher Award Ad dress by H. A. Liebhafsky entitled "Modern Analytical Chemistry—A Sub jective View." The two letters below reflect typical readers' viewpoints. While Dr. H. A. Liebhafsky's feature article in the June issue of ANALYTICAL CHEMISTRY raises many interesting and thought-pro voking points, I must respectfully disagree with his main thesis that chemistry is going out of analytical chemistry. Every instrumental technique has a chemical basis and involves the measurement of chemical param eters, even if indirectly. While instrumental methods have dis placed many of the more tedious chemical manipulations, reference to chemical standards is still re quired in most cases. So-called "trends" can be mis leading because they view only short periods of scientific development; instrumental analysis is flourishing now because it can build directly on decades of patiently gathered chemical information. The really important work in analytical chem istry, as far as long range develop ment is concerned, is still that which deals with basic chemistry—investi gation of new reactions, study of re action mechanism under analytical conditions, quantitative study of interferences, evaluation of analyti cal reactions and processes under extreme conditions, exploration of chemical and physico-chemical phenomena for application to iden tification and measurement. It does seem sometimes that the schism between the industrial and academic viewpoints of analytical chemistry is widening. Industrial research in analytical chemistry seems to be going more and more in the direction of devising faster, cheaper, and more reliable analyti cal methods while the method de velopment still carried out in aca-
