THE COLLECTION OF MINERALS 
the French crystallographer Haiiy, and Andalusite is named from the 
ancient province Andalusia, in the South of Spain, where it was first 
found. This last name is an example of the practice of naming some 
minerals after the place where they were discovered. Some mineral 
names which do not end in 7te are survivals of a time when the science 
was in its infancy and recognized few species. Many of these, as 
Quartz, Garnet, Gypsum, Corundum and Spinel, are so old and well 
established that they have come down to us unchanged. 
GUIDE TO THE COLLECTION 
The collection of minerals displayed in the Morgan Hall of Minerals 
is without question one of the finest to be found in the world. Although 
remarkably complete in its representation of most of the mineral species 
known to science, this collection is especially noteworthy for its as- 
semblage of splendid examples of the commoner and more widely distrib- 
uted minerals. 
The visitor should begin with the first of the table cases to the left 
of the entrance and proceed from left to right along each side of every 
case throughout the series, advancing from east to west along the south 
side, crossing to the north side at the west end of the hall and following 
the numbering of the cases back to the east entrance. Each case is 
furnished with a descriptive label referring to its contents and indicat- 
ing the high case of the series, arranged down the center of the hall and 
along the south wall, which contains large and handsome specimens of 
the same species. These latter are placed in close proximity to the 
corresponding table cases of the principal series and can be readily 
located. 
ELEMENTS 
Cases A and 1 
This small but important division of the mineral classification 
includes those elements which occur in nature uncombined, or in a 
“native” state, as native gold and native bismuth. Chemically they 
are the simplest of all minerals and consequently the best with which 
to begin the inspection of a series which increases in chemical complexity 
as it develops.
