ACKNOWLEDGMENTS 



The authors must express their gratitude to the members of 

 the staff of Davidson Laboratory who have assisted in the investigations 

 which have been described. Mr.M. Chiocco has been especially help- 

 ful in carrying out the experimental work of the large-array float inter- 

 action tests. Dr. D.Savitsky and Mr. E.Numata have given helpful 

 advice on all aspects of the work.
