Seager; Associate Professors, Robert R. Beishline, Ervin P. Guymon, Bryant A. Miner, Garth L. Welch; Assistant Professors, Arleigh V. Hartkopf, H. Stephen Stoker. The Chemistry curriculum provides a sound foundation in both the facts and principles of chemistry. Physics and mathematics are emphasized since these subjects are essential to an adequate understanding of chemistry. The required courses in English and the elective areas insure study in nontechnical subjects; broadening the student's general education and enabling him to relate his study of chemistry to other fields of knowledge. The Department of Chemistry offers three beginning courses or sequences. Chemistry 11, 12, 13 is a series of elementary courses for students who will take chemistry for one year or less. Chemistry 11 followed by Chemistry 13 is a sequence intended primarily for students of family life. Chemistry 24, 25, and 26 is the basic beginning sequence for students majoring in areas which require more than one year of chemistry. 110 111
