mathematics to analytical chemistry, A N A L Y T I C A L C H E M I S T R Y will in
clude a Fundamental Review entitled "Chemometrics" beginning in 1980. Since this new specialty is becoming a formal part of graduate education in analytical chemistry at a growing number of academic institutions, this new service should be a significant ed ucational aid in the training of mo dern analytical chemists. Finally, the author wishes to apolo gize to his analytical colleagues for covering t h e developments of our science in t h e 1970's with such a nar row bandpass. All that can be offered in defense is t h e rationalization given in the introduction and a firm belief t h a t analytical chemistry is moving to the forefront of t h e physical sciences as a science t h a t exploits t h e limits of mathematics to obtain the informa tion necessary to solve t h e problems of a growing society.
