22 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1947 



The last 2 weeks of the season were spent in going over Lower 

 Eocene beds in the Wind River Basin of central Wyoming and in 

 examining and making a collection from an isolated occurrence of 

 Duchesne River, Upper Eocene, beds in the northern part of the 

 Wind River Basin. 



Associate Curator D. H. Dunkle, accompanied by F. L. Pearce, left 

 for field work near Lamy, N. Mex., prior to the close of this fiscal year. 

 There, assisted by G. F. Sternberg, they began quarry operations at a 

 Triassic locality for an exhibition slab of ancient amphibian skulls 

 and other skeletal parts belonging to the genus Buettneria. This has 

 now been quarried out and is ready for shipment to the Museum. If 

 the season permits, they expect to examine other localities and forma- 

 tions of still greater age for fossil fish and primitive tetrapods in the 

 general region of east-central New Mexico, with the hope of building 

 up a more representative collection of these forms for our study 

 collection. 



The 5-nionth sojourn in Japan of Curator W. F. Foshag and 

 Associate Curator E. P. Henderson may well be considered a field 

 trip, since, whenever time permitted, studies were made on mineral- 

 ogical subjects, local universities were visited, and arrangements for 

 exchange of material were concluded. 



PUBLICATIONS 



Fourteen publications were issued during the year: One Annual 

 Report, three Bulletins, two Contributions from the National Her- 

 barium, and eight Proceedings papers. A list of these is given in the 

 complete report on Smithsonian publications, appendix 12. 



The distribution of voliunes and separates to libraries and other 

 institutions and to individuals aggregated 34,952 copies. 



MEETINGS AND SPECIAL EXHIBITS 



The Smithsonian continued to make available the auditorium and 

 lecture room of the Natural History Building to educational, scien- 

 tific, welfare, and governmental organizations and groups for meet- 

 ings and lectures. During the year 275 groups availed themselves 

 of this opportunity. The foyer and adjacent space in the Natural 

 History Building were in constant use during the year for a series of 

 15 special eidiibits sponsored by various groups, including the Smith- 

 sonian Centennial exhibit, which ran from August 10 to September 

 27, 1946. In addition, 23 special exhibits were held by the division 

 of graphic arts — 12 of etchings, lithographs, and other prints by 

 various artists, and 11 of photographs.
