INTRODUCTION. 
The Guide locates, by means of carefully prepared plans and 
a system of numbers, the collections and principal objects of 
interest in the Halls, Courts, Alcoves, and Galleries. The dia- 
grams are accompanied by descriptions in sufficient detail to add 
interest to the specimens and collections, but not attemping 
exhaustive treatment. 
Because of their historical significance the Columbian Rotunda 
and the Columbus Memorial Museum are described first. They 
are followed by the Courts and by the Departments, which are 
taken up separately in the order of their usual sequence, begin- 
ning with Natural History — Geology, Botany and Zoology — and 
concluding with the Departments relating to Man and His Works 
— Anthropology, Industrial Arts, and the Museum of the World’s 
Railway. An account of the Library and Lecture Hall is added. 
In the appendix will be found an alphabetical list of all donors, 
loan contributors, and collectors.
