ist.’ This chapter is, not inappropriately, headed * The Limit 
of Humanity,’ and as there are twenty-seven chapters, it will 
be seen that Professor Elliot covers some ground! He has 
some elaborate tables, and is fond of figures—' Oligocene, 
3,200,000 years ago,’ etc.; impressive, but not convincing. 
Speaking of Ice-Ages, the author admits ‘ the question is 
really one of geology, and as James Geikie, Penck, Bruckner 
and Sollas (an unusual quartette !) agree as regards the general 
scheme of four Ice Ages, their opponents ought to shew wherein 
their geology is wrong.’ Personally we thought this had often 
been done. ‘ Boyd Dawkins, Lamplugh, and other anthro- 
pologists in this country ’ object to the arrangement ! On the 
question of pigmy-flints the author seems to be under the 
impression that they were all made by ‘ the pigmy flint people 
who belonged to the Mediterranean race.’ He admits ‘it is 
very difficult to understand how they got to Australia.’ Quite 
so, and in recent times the Australian aborigines used 
stone axes almost identical in type with those found in York- . 
shire, but nobody suggests that the people of East Yorkshire 
in neolithic times migrated to Australia ? There are not many 
aspects of the subject neglected by Professor Elliot, and as 
he gives an enormous number of references to publications, 
the student of any particular subject can refer to these. Among 
the illustrations are reproductions of the restorations of the 
different types of pre-historic man, by Professor Rutot, though 
these all seem to bear a strong family likeness. 
In ‘AN INTRODUCTION TO THE STUDY OF PREHISTORIC 
ART,’ * Mr. E. A. PARKYN gives a remarkable series of illus- 
trations of the artistic efforts of early man during the Palzo- 
lithic, Neolithic, Bronze and Early Iron Ages. There are also 
chapters on ‘ Late Keltic Art,’ etc. Mr. Parkyn has gathered 
together an enormous number of representations of extinct 
animals, as drawn by palzolithic man on bone, ivory, on the 
walls of caves, etc., but on examining them one wonders 
whether all the pictures really represent the work of primitive 
man. And similarly, though Mr. Parkyn states his case with 
caution, we should be inclined to think that many of the 
pieces of pottery ascribed to the Neolithic or new Stone 
Age, should really be looked upon as of the Bronze Age. That 
is certainly our opinion with regard to the East Yorkshire 
pottery mentioned. The Art of the Bronze Age, Early Iron 
Age, etc., is dealt with very clearly and very fully, and examples
