PREFACE 
I take this opportunity to express my gratitude to all those, both 
in America and in Rome, who have so kindly assisted me in the 
prosecution of this investigation. 
I desire especially to thank the officers of the American School 
of Classical Studies in Rome for the many courtesies shown me as 
a research fellow of the School, and the Carnegie Institution of 
Washington for the generous aid by which the publication of this 
work has been made possible.
