SECRETARY'S REPORT 21 
of vertebrate paleontology, a field party spent several weeks at a Tri- 
assic rock quarry near Lemy, N. Mex., recovering 19 blocks of the 
bone-bed material. Composed primarily of the dissociated remains 
of the giant stereospondylous amphibian Buettneria, the collection in- 
cludes at least 35 skulls of this animal, as well as a multitude of other 
skeletal parts. Dr. Dunkle also made a search for fossil fishes in the 
Jurassic beds east of Santa Rosa, N. Mex., and his party obtained 87 
specimens representing two genera of primative teleosts. Prior to the 
close of the year Dr. Dunkle and A. C. Murray undertook field work 
in the marine Pierre Shale north of Lusk, eastern Wyoming. 
PUBLICATIONS 
Twenty-four Museum publications were issued during the year: 
1 Annual Report, 4 Bulletins, 17 Proceedings papers, and 2 papers in 
the Bulletin series, Contributions from the United States National 
Herbarium. A list of these is given in the complete report on Smith- 
sonian publications, appendix 12. Special mention should be made 
of Bulletin 193, published in December 1947, comprising a list and 
index of all the publications of the United States National Museum 
from 1875, when the first Museum Bulletin was issued, until the end 
of 1946. It is the first such list and index to be published in more 
than 40 years. It was compiled in the editorial division. 
The distribution of volumes and separates to libraries and other 
institutions and to individuals aggregated 50,970. 
CHANGES IN ORGANIZATION 
A number of important changes in the Museum organization were 
effected during the year. 
On July 31, 1947, the department of biology was divided into two 
departments—zoology and botany—the former division of plants (the 
National Herbarium) being raised to the status of a full department. 
Ellsworth P. Killip was named head curator of the department of 
botany, while Dr. Waldo L. Schmitt continued as head curator of zool- 
ogy. Three divisions were created in the new department—phanero- 
gams, grasses, and cryptogams—and toward the close of the year a 
fourth one, the division of ferns, was established, to become effective 
on July 1, 1948. 
The division of aeronautics was separated from the department 
of engineering and industries on July 31, 1947, to become the nucleus 
of the National Air Museum, established by Congress in 1946 as a 
bureau of the Smithsonian Institution. This change took from the 
department Paul E. Garber, curator of aeronautics, with 28 years 
of service in the Museum, to become curator of the National Air 
Museum.
