shows 1 m. 70 cm. (a trifle over 5\ ft.).
The tusks found at Tilloux also appear to indicate that they belonged
to an animal even larger than the mammoth of the Petrograd Museum of
Natural History.* Two molars found in these same Tilloux deposits
presented in their general aspect and the number and form of the ridges
the well-known features of Ehphas meridionalis. The fact, however, that these elephant remains had been found in association with prehistoric artefacts and that molars both of El. primi-genius (the mammoth) and of El. antiquus should
also be met with here under quite similar conditions was very
noteworthy, as while remains of two of these species are occasionally
found together, the association of all three in a single deposit is
British Museum of Natural History contains the finest mammoth skull
that has been found in England. It comes from the brick earth at
Ilford, Essex. The tusks project 10 ft. 6 in. beyond the sockets.
Unfortunately the skull is the only part of the skeleton that has been
preserved, although when it was found the entire skeleton appears to
have been present·!
Mammoth remains from the State of Illinois are to be seen in the Field Museum of Natural History, Chicago. With a skull of Mastodon americanus from
Yorkville, Illinois, was preserved a single tusk the circumference of
which was 23 in., the length along the curve being 6 ft. 3 in., while a
direct line from one extremity to the other (the chord) measures only 3
ft. 7 in., these dimensions showing the great
characteristic differences of four of these tusks are brought out in
Fig. 4, p. 502, of M. Boule's paper; all being given on a scale of
1:30. The figures indicate the following approximate measurements of
the Petrograd mammoth tusk: length between extremities (the chord) 1.65
m., length along the outer curve 2.80 m. compared with 2.85 m. and
(ap-prox.) 3 m., or 9.84 ft. for the tusk of Tilloux.
