Burnham — Social Insects in Fossil Record 
127 
ACKNOWLEDGEMENTS 
This study was originally intended as a brief survey of the social 
insects in the fossil record but underwent rapid expansion shortly 
after its initiation. This is partly due to my burgeoning interest in the 
subject matter, partly due to the vast amount of material requiring 
my attention, and partly due to the stimulation and encouragement 
received from friends in the academic community at Harvard. It is 
to the following friends that I extend my thanks and appreciation: 
K. M. Horton, Paul Strother, Robert E. Silberglied, Kenneth 
Miyata, and N. E. Woodley. Special thanks are given to F. M. 
Carpenter for his continuous guidance and advice, for his patience 
as my photographic assistant; and most of all, deep appreciation 
is extended to him for providing the inspiration integral to the 
success of this study. The Royal Ontario Museum, Toronto, is 
gratefully acknowledged for the loan of the Eocene vespoid. In 
addition, partial financial support is acknowledged to National 
Science Foundation Grant DEB 78-09947 — F. M. Carpenter, 
principal investigator.
