These motion picture films are available on loan to schools, universities, 
and societies or institutions. No rental fee is charged, but the borrower is 
required to pay the shipping charges. 
LANTERN SLIDES 
Sets of lantern slides are being assembled for loan to educational 
institutions and lecturers with the object of stimulating interest in natural 
history. A nucleus of sets has been established and includes the following 
series: Indians and Eskimos, dinosaurs, topographic forms, reptiles and 
amphibians. A large collection of slides of Canadian birds now available is 
being prepared in sets, but pending the final arrangements of the sets, 
selections are being made to meet the needs of individual inquirers. The 
collection will be added to gradually and when present plans materialize 
sets of lantern slides will be available to represent adequately, and illustrate, 
Canadian fauna and flora, the Indians and Eskimos of Canada, the 
geography of Canada, and the natural sciences. 
Special sets of lantern slides arc arranged for use in the automatic 
balopticon installed in the rotunda of the Museum. This projector has 
already proved its usefulness as an educative medium. 
STILL PHOTOGRAPHS 
A large collection of petrographic negatives has been accumulated 
by the National Museum and the Geological Survey, Canada, with which 
the Museum is closely associated over a period of more than seventy years. 
Prints, enlargements, and lantern slides are made from these negatives and 
are sent at cost price to schools and universities requiring these visual aids 
in teaching. 
Each year many requests are received from authors, journalists, and 
publishers for photographs to illustrate special articles. The National 
Museum welcomes such requests and aims to assist writers and publishers 
in every possible way. 
LOAN OF SPECIMENS > ■ 
Specimens of birds, small mammals, Indian clothing, and implements 
are available for loan to teachers, but up to the present very few loans 
have been made outside of Ottawa. This service has developed on account 
of the demand from teachers in local schools for this assistance and very 
little expense is involved either to the Museum or the teachers. The 
teachers call at the Museum for the specimens and return them within a 
time limit. 
To extend this service outside of Ottawa would involve considerable 
expense to the Museum in providing the additional loan sets that would 
be required, and it is considered that the expense of shipping renders the 
feasibility of extending this service impracticable. If in the future loan 
centres are established outside of Ottawa consideration may be given to 
extending this service.
