REPORT OF NATIONAL MUSEUM, 1908. 55 
Transactions of the St. Louis Academy of Science, Volume VIII, 
1898. The entire exhibition and a large part of the study series were 
overhauled, partly rearranged, and many of the specimens reduced 
in size by careful trimming. Much progress was made in the num- 
bering of specimens and the preparation of the card catalogue. The 
investigations carried on were almost entirely limited to the work 
of the paleobotanists of the Geological Survey. Dr. A. C. Peale was 
detailed for service in connection with the explorations of the 
Geological Survey in Montana during the summer of 1907. 
DISTRIBUTION AND EXCHANGE OF SPECIMENS. 
Of the regular sets of duplicate specimens prepared for educa- 
tional purposes 152 were distributed during the year, as follows: 
Sixty-one of nonmetallic minerals and ores, 53 of fossil invertebrates, 
24 of rocks, 8 of minerals, 3 of weathered rocks, and 3 of marine 
invertebrates. The total number of specimens included in these sets 
was 8471, besides which nearly 3,500 specimens were sent out in 
special sets. 
Including the material to be worked up for publication by the 
Museum, there were placed in the hands of specialists not officially 
connected with it, for study, 6,215 specimens from the department of 
biology, 2,844 from the department of geology, and 29 from the 
department of anthropology, a total of 9,088 specimens. 
In carrying on exchanges with scientific institutions and indi- 
viduals 13,993 duplicate specimens were used. Of this number 1,630 
were geological, 153 anthropological, and 12,210 zoological and 
botanical. An idea of the extent of the Museum’s relations im this 
regard may be obtained from the following list of establishments and
