leaf or cotyledon, and foliage-leaves with more or less parallel 
veins, without the irregular network found in a dicotyledonous 
leaf. The Dicotyledons, on the other hand, have a pair of 
cotyledons and foliage - leaves with an irregularly netted 
venation. The arrangement of the vegetative parts of the 
plant is based on its separation into root, stem, and leaf. 
In the right-hand wall-case the upper series of specimens illus- 
trates the leaf, its form, veining, direction, the characters of its 
stalk and stipules, its modification for special purposes, and its 
arrangement on the stem and in the bud. Below the stem and 
root are similarly treated, and above are some anatomical 
drawings. The display of the root is continued in the lower 
part of the opposite wall-case. 
In the central case the chief types of the flower with its 
parts, the fruit, and the seed are exhibited. 
At the back of the bay is a large transverse section of the 
Karri tree {Eucalyptus diversicolor) of Western Australia, a 
species which grows to a height of 400 feet. The tree from 
which the section was cut was about 200 years old when felled. 
The Introductory Collection of Minerals will be found in the 
gallery devoted to that department of the collection (see p. 85).

Zoology is likewise being added. 
The examples of Domesticated Animals are not yet per-

series can be regarded as at all representative. The chief ex- 
hibits comprise Horses, Cattle, Sheep, Goats, Dogs, and Eabbits. 
One of the main objects of this series is to show the leading 
characteristics of the well-established breeds, both British and 
foreign. In addition to Domesticated Animals properly so
