28 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1958 
November 1957 he attended the annual meeting of the Society of 
Vertebrate Paleontology in Philadelphia, Pa., and the Geological 
Society of America meetings in Atlantic City, N.J. During the 
first week of December Dr. Gazin studied Eocene and Oligocene col- 
lections at Princeton, N.J., and the American Museum of Natural 
History. In February 1958 he studied middle Eocene mammalian 
collections from the Green River beds of northeastern Utah at the 
Carnegie Museum in Pittsburgh, Pa. 
During September 1957 E. P. Henderson, associate curator of 
mineralogy and petrology, accompanied by photographer Jack Scott, 
made an extensive trip in order to study the morphology and surface 
features of meteorites and to photograph large collections. They 
spent some time going west and also on their return east at the 
Battelle Memorial Institute in Columbus, Ohio, witnessing the cut- 
ting operation of the Grant, N. Mex., meteorite. Meteoritic iron 
requires much more time to cut than one anticipates. These cut sec- 
tions will enable the specialist to study the thermal penetration. 
Henderson and Scott examined and photographed the meteorites at 
the University of Kansas, Iowa State College and the State Univer- 
sity of Iowa, Chicago Natural History Museum, and Wooster and 
Marietta Colleges in Ohio. These studies are especially important 
now that manmade satellites are being placed in outer space. Mr. 
Henderson spent 2 days in May examining the meteorite collection 
in the Philadelphia Academy of Natural Sciences. He also acquired 
new material for the Museum’s collections. 
Dr. D. H. Dunkle, associate curator of vertebrate paleontology, 
spent 2 days in October 1957 studying various Mesozoic teleostean 
fishes in the Bayet collection of the Carnegie Museum in Pittsburgh. 
In March 1958 he devoted 2 days to the study of a restricted group of 
elopoid fishes from the Cope collection at the American Museum of 
Natural History. 
In the company of two paleontologists of the U.S. Geological 
Survey, Dr. Richard S. Boardman, associate curator of invertebrate 
paleontology and paleobotany, spent 6 days in the fall of 1957 collect- 
ing bryozoans, brachiopods, and corals from all the stratigraphic 
zones of middle Devonian rocks along the falls of the Ohio River. Dr. 
Boardman attended the annual meeting of the Geological Society of 
America in Atlantic City, and in March 1958 he purchased some well- 
documented rhomboporoid Bryozoa collected from the middle Devo- 
nian Hamilton rocks of the Buffalo, N.Y., area. 
Dr. Porter M. Kier, associate curator of invertebrate paleontology 
and paleobotany, spent several days in October 1957 examining and 
studying Paleozoic echinoid collections at Yale University and Har- 
vard University. Here he discovered several type specimens never
