Seager, Garth L. Welch, Bryant A. Miner; Associate Professor, H. Stephen Stoker; Assistant Professors, Helen J. James, Michael R. Slabaugh. 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. 112 113
