340 Notes and Comments. 
“MEN OF THE OLD STONE AGE, 
their Environment, Life and Art’ is the title of a volume 
recently issued by Prof. H. F. Osborn.* It is based’ upon 
the Hitchcock Lectures of the University of California, 1914, 
but it contains details of later discoveries, notably of the Pilt- 
down remains. These discoveries in Sussex have caused 
considerable discussion, and indirectly have led to the ap- 
pearance of many books on prehistoric man, the present being 
among them. Professor Osborn is well known for his work in 
America, and he has spent three weeks among the French 
caves, a map showing the route taken being given at the end 
of the volume. 
DIVISIONS OF TIME. 
He deals in detail with the human remains of various 
deposits and periods, though we fear his time divisions are 
so numerous and varied that they will not readily be adopted 
by English archeologists. For instance, he refers to the 
“Transition to the Pleistocene, The First Glaciation, The 
First Interglacial Stage, The Trinil Race, The Second Glacia- 
tion, The Second Interglacial Stage, The Heidelberg Race, 
The Third Glaciation, The Piltdown Race, The Second 
Period of Arid “Climate, Close of the Third Interglacial, The 
Fourth Glacial Stage,’ and so on. Among them we find such 
headings as ‘Date of Pre-Chellean Industry,’ Chellean Industry,’ 
‘ Acheulean Industry,’ “ Arctic Tundra Life,’ etc. 
RESTORATION. 
A feature of the book, which will appeal more particularly 
to the “ general’ reader, is a series of restorations of the features 
of prehistoric men of different periods. Thus there is Pithecan- 
thropus, the Java ape-man, the Heidelberg man, the Piltdown 
man, the Neanderthal man, the Cro-Magnon man, etc. But 
there is almost a family resemblance between some of these, 
though they are separated by thousands of miles, and, in time, 
by periods estimated in hundreds of thousands of years. For 
the most part they have quite refined features, and some at 
any rate have features quite American. This is due no doubt 
to the individuality of the artist being reflected in his work, 
but it detracts from the likelihood of the restorations being 
accurate. 
PROF. OSBORN’S RESEARCHES. 
Professor Osborn covers considerable ground in his book. 
Not only does he refer to the remains of the osteological re- 
mains of the races he describes, but the associated implements, 
the rock carvings, paintings, sculpturings, and even the 
associated fauna are described in a detail which is almost
