ii Preface. 



on the completion of this monumental work, which is marked by 

 progress and new results on every page, and for which every student of 

 Chinese is largely indebted to him. As our archaeological research 

 advances, the necessity of a special archaeological dictionary will be 

 more and more felt. 



The generosity of Mrs. T. B. Blackstone in contributing a fund 

 toward the printing of this volume is gratefully acknowledged. 



I have to thank Dr. O. C. Farrington, Curator of Geology, for the 

 mineralogical definitions of many specimens, and Mr. H. W. Nichols, 

 Assistant Curator of Geology, for manifold advice on technical ques- 

 tions. 



The manuscript was completed in October, 191 1.
