This collection of notes was assembled as a supplement and guide to a five-day short course presented at the University of California at Berkeley, September 22-26, 1969. The scope of subject matter, while limited to combustion as a source of air pollution, at the same time is intended to give the broadest possible exposure within that area. The spectrum is deliberately wide, ranging from fundamentals of combustion and combustion reactions through performance of combustion systems and to legal and administrative control. Contributors to this compendium and lecturers in the subject were solicited from academic and public organizations. Most of the authors are from the statewide University of California and the California Department of Public Health. Notable individuals with particular ex­ pertise, from other institutions, were also invited to contribute. The choice of instructor in each case was based upon a desire to col­ lect a cross-section of outstanding individuals, each highly qualified technically in his field. These notes reflect the freedom which each author was encouraged to follow in providing supplementary material for his lecture. The staff of Continuing Education in Engineering, Professor Thomas Hazlett and Daphne Stern, deserve commendation for their effective and successful handling of the innumerable details which were encountered. Professors Robert Sawyer and Laurence Caretto are herewith gratefully acknowledged for their support in the seemingly uncountable tasks ne­ cessary to assemble the entity which is represented.
