marine worm tubes (Sevfude), presenting just the 
same appearance as we often see on the shells of large 
oysters of the present day. 
We now come to the Tertiary or Kainozoic Life 
period, which comprises the Eocene, Oligocene, 
and Pliocene formations. ‘The Eocene strata occupy 
in England two distinct tracts, termed the London and 
Hampshire Basins. Among the organic remains of 
- the London clay are species of mammals, birds, turtles, 
crocodiles, fishes, mollusca, crustacea, protozoa, and 
plants. The climate of the period was rather tropical. 
Flower and fruit-producing plants are now found with 
the birds and mammalia. There are shown in End 
Wall Case g fossil specimens of Chelonia or turtles, 
as well as the humerus and part of the jaw of the 
Glyptodon, a great Armadillo-like mammal, which 
flourished in the last geological age in the region 
of South America, where there is still a fauna 
different in character from that of other parts of 
the world. Some of the birds of the earlier Tertiary 
period were of enormous size, and similarly large birds 
have been found in a semi-fossilized condition in the 
Southern hemisphere. The bones of the Dzxornts 
from New Zealand belonged to a remarkably large 
wingless bird. Judging from the vast number of 
remains of this bird found in New Zealand, and 
from the extraordinary diversity in size of their 
skeletons, the Dinornis or gigantic Moa must have 
enjoyed for long ages complete immunity from the 
attacks of wild beasts and man. The Moa varied 
in height from three to upwards of ten feet. The 
bones here shown are portions of those of Dixornts 
casuarinus, and D. elephantopus. ‘The latter was 
undoubtedly a bird of great strength and heavy- 
footed, as the name (elephant-footed) indicates. In 
the same case are shown cast of the bones and
