placed a nuinber of large and striking objects, of too great a size 
to be contained in the wall-cases. The first is a nearly complete 
skeleton of the American Mastodon 
(fig. 25), an animal closely allied to 
the Elephants, from which it is 
chiefly distinguished by the cha.rac- 
ters of its molar teeth ; followed by 
a skeleton of the existing Indian 
Elephant, placed for comparison 
with the extinct species of that 
genus. Beyond is the skull of an 
Elephant {Elejphas ganesa), remark- 
able for the immense length of its 
tusks, from the Siwalik Hills of 
India, and another of the Mammoth 
(Mep?oas primigenius) with huge 
curved tusks, in a perfect state of 
preservation, found in the brick 
earth at Ilford in Essex. Alongside 
the former is placed the largest 
known tusk of the modern African 
Elephant. Then follow skeletons 
of the great extinct Irish Deer 
(Cervus giganteios), male and female, 
the former distinguished by its 
magnificent palmated antlers, re- 
sembling those of a fallow deer on 
a large scale. 
Near by is placed a model of a 
skeleton of theDinoceras (fig.29),one 
of the most remarkable of the many 
wonderful forms of animal life dis- 
covered in the Tertiary beds of the 
western portion of the United 
States of America. This animal 
combines in some respects the 
characters of a rhinoceros with 
those of an elephant, and has others
