NEW ZEALAND 
GEOLOGICAL COLLECTIONS. 
The arrangement of the New Zealand Geological 
Specimens in the Museum is of # two-fold character. 
The first is founded on a systematic comparison of 
the characters of the different Rocks and Fossils repre- 
sented in the Collections, and is intended for the 
assistance of those who desire to acquaint themselves 
with the general features of the structure of these 
Islands. 
With this view, the Rock specimens have been 
arranged according to the system of Petrology given 
in a recognized standard work, and the Fossils have 
been arranged, so far as can be yet determined, in the 
order of their relative age or stratigraphical position. 
This section of the Collection of Fossils has been 
rendered complete in so far as it contains a specimen 
of each species of Fossil that has been distinguished, 
but as the localities whence the Fossils were obtained 
ave rarely strictly comparable on a stratigraphical 
basis, geographic arrangement only has been adhered 
to in the Catalogue. 
The second form in which the Geological Collec- 
tions are represented in the Museum recognizes only 
this geographic distribution, so that the specimens 
illustrative of the Geology of any particular district 
may be referred to with ease, either in the Catalogue 
or by inspection of the Rocks and Fossils. 
Special Collections, devoted to the illustration of 
the Minerals of chief ceconomic interest, complete this 
section of the Museum.
