ANTIQUITY OF THE PILTDOWN RACE 309 
" he agreed with the authors of the paper that the deposit 
containing the human remains belonged to the Pleistocene 
age, and that the Pliocene mammalia in it — Mastodon 
aruernensis and the rest — had been derived from a Pliocene 
stratum formerly existing in that area." That opinion, 
coming from one who has the right to speak with 
authority, must evoke surprise. When he found the 
remains of the same species of Mastodon in the Dove- 
holes cave in Derbyshire in 1903, unaccompanied by 
human remains. Professor Boyd Dawkins unhesitatingly 
assigned the contents of that cave to the Pliocene period ; 
but when the same remains are found in Sussex, accom- 
panied by humgun remains, the deposit, in his opinion, 
should be referred to a much later date. In Professor 
Boyd Dawkins' opinion man is an evolutionary product 
of the Pleistocene period, and first reached Britain about 
the middle of that epoch. Much more guarded opinions 
were given by Mr Clement Reid and by Mr A. S. 
Kennard, who have made a special study of the later 
deposits in the south of England., " It was impossible," 
said Mr Reid, " to speak with confidence, but the whole 
evidence suggested that the Piltdown deposit and the 
plateau on which it rests are not preglacial or even early 
Pleistocene ; they belong to a period long after the first 
cold period had passed away, but they occur at the 
very base of the great implement-bearing succession of 
Palaeolithic deposits in the south-east of England." 
Mr Kennard regarded the Piltdown gravel as being of 
the same age as the 100-foot terrace of the Thames 
valley, which, as we have already seen, is made up of 
strata belonging to various stages of the Pleistocene 
epoch. Mr Kennard's opinion Is of the greatest interest, 
because it was from the 100-foot terrace of the valley of 
the lower Thames, at a depth of 8 feet. In 1888, that a 
human skeleton was found at Galley Hill. If Mr 
Kennard Is right, the Galley Hill man, who was of the 
same type as modern man, must have been almost 
contemporaneous with the very primitive human being 
reconstructed by Dr Smith Woodward. Mr E. T.
