other bones, including that of the ball and socket 
joint of the humerus. Most striking objects below 
are the pelvis and sacrum of another elephant from 
Mundesley. ‘There is a fine humerus or upper part 
of the fore leg of an elephant, found in 1836, after a 
very high tide, exposed in the cliff near Bacton (Wall 
Case 14). Several specimens of the femur, thigh 
bone, and of the humerus or fore leg of elephants, 
from the same neighbourhood, with many teeth, and 
the lower jaw of Zlephas meridionais, found near 
Mundesley, help to supply evidence as to the 
character of the fauna of the Forest Bed _ period. 
The gigantic height and size of the elephants of the 
Forest Bed period may be judged from an inspection 
of these bones in conjunction with the monster tusk 
(Wall Cases 15 and 16) found at Runton, immediately 
under the Forest Bed, presented to the Museum by 
fees EF. Buxton. This tusk is nearly ten: feet in 
length and two feet eight inches in girth. Dr. 
Falconer was of opinion that the animal to which 
this tusk belonged must have stood between sixteen 
and seventeen feet high. 
The concluding Wall Cases represent he fossil 
remains of the Quaternary or Post-Tertiary formation, 
which include beds of drift sand, gravel, and clay, 
deposited by glacier, ice-sheet, and iceberg action, 
during a period of intense cold. As a consequence, 
the Forest Bed period was succeeded: by one of 
Arctic temperature, when the area was overspread by 
enormous masses of sands, gravels, and clays that 
now form for a great thickness the agricultural and 
brickearth bearing soils of East Anglia. The Quater- 
nary deposits consist of boulder clays and gravels, of 
raised beaches, of valley gravels and brickearths, and 
lastly of blown sand, tufa, cavern deposits, submarine 
forests, and peat. When the more intense portion of
