 association in Peking to bring together the 

 geologists and naturalists resident in Peking 

 and the vicinity for discussion of problems of 

 mutual interest and the furtherance of intel-

 Far East. Several meetings have been held at 

 the residence of Dr. Roy Chapman Andrews 

 at the headquarters of the Third Asiatic Expe- 

 dition, at the residence of Dr. J. G. Anderson,
