PREFATORY NOTE 
It is the purpose of this Gurpe to call attention to the more important exhibits 
that the visitor will see as he passes through the halls. More detailed information 
regarding the specimens may be obtained from the labels or from the Guide Leaflets. 
It is frequently necessary to rearrange the exhibits in the halls in order to provide 
space for new material which is continually being received or to put into effect 
advanced ideas regarding methods of exhibition. In some instances therefore, 
the arrangement described is not wholly that in existence at the date of issue of the 
Guipg, but rather what will be when certain installations now in progress are com- 
pleted. This is true for the halls devoted to geology and invertebrate paleontology 
and to some extent in the exhibit of the Indians of the Woodlands and in those of 
local mammals, mammals of the world and insects. The sergeants on’ each floor 
will always direct the visitor to any collection on the given floor

The halls are named according to the position they will have in the completed Museum 
building, which will consist of four long facades facing east, west, north and south respectively, 
each connected with the center of the quadrangle formed, by a wing extending between 
open courts. ‘Thus the hall at the eastern end of the south facade (the only facade completed) 
becomes the ‘‘southeast pavilion.”’
