24 
dinosaurs. A life-like restoration by L. S. Russell of an Alberta dinosaur, 
natural size, accompanies this exhibit, which was assembled by C. M. 
Sternberg. . 
A loan collection, prepared by A. La Rocque, representing sea shells, 
displays examples of the Canadian shell fish most highly prized for food, 
and includes a series of tropical shells selected largely with reference to the 
uses man has made of them and the beauty of their colours. Foremost in 
their human interest among the shells of this collection are the cowries, 
which were once extensively used as money by many native races. The 
coloured races of Africa used them as a medium of exchange just as the 
white man has used gold. 
Twenty-five sets of fossils were supplied during the year for the use 
of teachers in High Schools. 
Classes from the Normal School in Ottawa were conducted through the 
Hall of Palseontology on six occasions early in the school year, by L. S. 
Russell. 
During the summer Dr. G. A. Stewart of Ohio State University and 
Dr. M. A. Fritz of the Royal Ontario Museum spent some time at the 
National Museum in connexion with work on the Illustrated Catalogue of 
North American Devonian fossils.
