ACKNOWLEGMENTS 



Initial stages of this study were done under a postdoctoral 

 fellowship provided by the Cabot Foundation, Harvard Univer- 

 sity, and a concomitant appointment at the Fairchild Tropical 



Science Foundation grants BSR-82-I0618, 78-04731, and 

 GB3 1 844X. Additional support for travel came from the Atkins 

 Funds and Cabot Foundation of Harvard University and the 

 Research Board of the University of Illinois at Chicago Circle. 

 I am deeply grateful to Dr. P. B. TOMLINSON of Harvard
