DISTRIBUTION AND EXCHANGE OF SPECIMENS. 
Over 30,000 duplicate specimens, recently separated from the

fishes, rocks, ores, and minerals, accurately named and labeled, were 
made up into several hundred sets for distribution to educational 
establishments. The number of sets actually sent out during the year 
was 261, including fossils, as well as the groups above mentioned;

who are conducting investigations for the Museum, as noted under 
the heading of researches, about 20,000 specimens; and upward of

other institutions and with individuals. The most noteworthy object 
disposed of in exchange was the full-sized restoration of the skeleton 
of the Dinosaurian reptile, Zréceratops, exhibited at both the Pan-
