INTRODUCTION. 
The Guide locates, by means of plans and numbers, the 
principal objects of interest in the Halls, Courts, Alcoves and 
Galleries. The Columbian Rotunda is described first. The 
Departments are then taken up separately in the order of their 
usual sequence Geology, Botany, Zoology, Ornithology, An- 
thropology and the Transportation collections. 
If a general view of the entire Museum is desired, it is 
suggested that the Departments be visited in the order above 
indicated. After viewing the Columbian Rotunda (see page 
13) the visitor may proceed through the Reading Room and 
Lecture Hall to the West Pavilion, where are installed the col- 
lections of Geology, (see page 17). The Halls should be vis- 
ited in the following order: 35, 36, 59, 60 and 61— Paleontology ; 
62, 63 and 64 — Meteorites and Mineralogy; 65 — Dynamic Geol- 
ogy; 66— Lithology ; 67 to 80 inclusive, except 76 and 77— Eco- 
nomic Geology and Metallurgy; 76 and 77— Geographic Geol- 
ogy. 
Returning to the West Court through Hall 35 the Botan- 
ical Department may be reached by the stairway in Alcove 102. 
The circuit of the galleries should be made from the West to 
the North, then to the East, and finally to the South Gallery. 
The Botanical collections are arranged on a geographical basis, 
and begin on the South ijallery with specimens from Asia, 
Europe, Africa, and follow with the South and North Ameri- 
can Series. 
After descending to the main floor the visitor may pro- 
ceed to the south side of the West Court and should visit the 
Halls of the Zoological and ’Ornithological Departments.
