18 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1948 
jaws, and a foot of the tillodont 7’regosus castoridens from the Bridger 
formation near Church Buttes, Wyo., the second skull of this rare 
mammal to be found during intermittent exploration covering 75 
years. Equally significant was the discovery of the rostral portion of 
the skull of Hsthonyx acutidens, an earlier member of the tillodont 
order from the Wind River beds of Wyoming. This specimen, found 
by H. A. Tourtelot, was transferred from the United States Geological 
Survey. Exceptionally valuable for exhibition purposes was the large 
slab of giant amphibian skulls and other skeletal parts representing 
the Triassic form Buetineria perfecta, secured by the associate 
curator’s party near Lamy, N. Mex. Other specimens that came as a 
result of the division’s field work were two well-preserved skulls of the 
Eocene primate Votharctus,; additional specimens of 7’rogosus, of the 
rhino Hyrachyus, and the tapir Helaletes; and skulls of the small 
rodents Mysops and Sevuravas. Jurassic fishes collected by the asso- 
ciate curator represent some of the earliest bony fishes and are im- 
portant in providing unusual specimens for growth studies. 
Engineering and industries —An outstanding accession in the divi- 
sion of engineering was the collection of railroad historical material 
assembled by the late Charles B. Chaney, Jr., totaling about 20,000 
items. Another railroad accession was a group of models showing the 
evolution of the equipment of The Empire State Express, the New 
York Central famous train. Various commercial firms continued their 
cooperation by contributing material relating to industrial products 
and manufactures, and interesting electrical items came from a num- 
ber of sources. Through the Dahlgreen fund 15 fine original prints 
of historical and technical importance were added to the graphic arts 
collections; included in the group are prints by Breughel, Goya, 
Delacroix, Blake, Daumier, Rodin, and Zorn. Among the photo- 
graphic material received was equipment used in the first practical 
synchronization of sound in motion pictures. An interesting acces- 
sion in the division of medicine and public health was one of the 
first of the so-called “drunkometer” instruments now used extensively 
by police departments to determine the amount of alcohol in the breath 
and tissues. 
History.—A notable acquisition in this division was a large numis- 
matic and philatelic collection from the estate of the late Victor L. 
Huberich, consisting of more than 2,500 specimens of United States, 
Canadian, and Japanese paper money and about 73,000 Mexican rev- 
enue stamps and Japanese postage stamps. This is a collection of 
unusual historical interest and is the first important addition to the 
Museum’s collection of United States paper currency in many years. 
The numismatic series were increased also by the addition of 72 com- 
memorative medals lent by the Bureau of the Mint. The most 
important addition to the costumes collection was a green silk, flow-
