I am particularly grateful to Francisco Varela for helping me with questions about the original model, and in giving me access to related, previously unpublished, materials (some of which are now presented in the Appendix). I am also grateful to Marita Prandoni, of the Santa Fe Institution, for her assistance in translating some of these materials.
Initial work on this detailed re-analysis of (Varela et al. 1974) was carried out with the help of my former student, Hyder Aswad.
All errors remain, of course, my own responsibility.
This report was written while I was a visiting researcher (1996/97) with the Swarm Project Group at the Santa Fe Institute. This visit was made possible by generous support from Dublin City University and the Swarm Project. Swarm has been supported by Grant No. N00014-94-1-G014 from the Department of the Navy, Naval Research Laboratory, acting in cooperation with the Advanced Research Projects Agency. Swarm has also benefited from earlier support from The Carol O'Donnell Foundation and from Mr. and Mrs. Michael Grantham.
I am indebted to the School of Electronic Engineering in DCU (particularly through the agency of its Head, Charles McCorkell) for continuing encouragement.
