Grace, at the time Senior Research Fellow with E. I. DuPont de Nemours Co., at the “Third Engineering Foundation Conference on Mixing” held in Andover (N.H.) in August 1971. Although the paper was never published, many copies of the presentation (some of them of third and fourth generation) have been in circulation for years and the work has been often quoted. It was felt, therefore, that by publishing Dr. Grace's work, we shall meet the needs of those who have been trying to get a copy of this work. Since Dr. Grace retired from active service, Dr. David G.R. Short, Engineering Consultant with DuPont, retrieved the manuscript and the figures and reissued both in March 1981. Subsequently, the paper was edited for publication in Chemical Engineering Communications. When editing the manuscript, I changed mainly the references to slides and to movie sequences which, unfortunately, are no longer available. Some slides were combined with the text and some had to be left out since the photographs shown on them were not of good quality. Some figures had to be redrawn either because the data points were not legible or because the axis description was missing. I have also filled-in the literature references which were missing in the original manuscript. I have preserved the original terminology and notation. The paper was not subject to our normal peer review but the high demand for copies of this presentation, which has persisted for over ten years, testifies to the value of Dr. Grace's work. —J. J.
