PREFACE. 
Mr. Charles Dawson's discovery of the Piltdown skull has 
aroused so much interest in the study of fossil man, that this 
small Guide has been prepared to explain its significance. Most 
of the known specimens important for comparison are represented 
in the exhibited collection by plaster casts ; and near these, in the 
same and adjacent cases, are arranged both human implements 
and associated animal remains to illustrate the circumstances 
under which early man lived in western Europe. 
Thanks are due to the Council of the Geological Society for 
permission to reproduce Figs. 4 (a, b), 5, 6 (a, b, d), 8-9 (a, b, d), 
and 12, from the Society's Quarterly Journal.

P.S. — The only important change in the second edition of this 
Guide is the addition of the figure and description of a bone 
implement found in the Piltdown gravel (pp. 11, 12).
