GLACIAL MAN. SKERTCIILY. 137 



he showed to be the cores from which the flakes for making 

 spear and arrow heads were struck. I have the original obsidian 

 core that led him to the solution (exhibited). John Evans — 

 the Sir John of later date — collected stone and bronze tools 

 assiduously, and had produced his great work on the Stone 

 Implements of Great Britain. It is a splendid catalogue, but 

 he was not much of a geologist. Sir John Lubbock, after- 

 wards Lord Avebury, did us the incomparable service of 

 inventing the terms " Neohthic " and '' Palseohthic " for the 

 two classes, pohshed stones, &c., as contrasted with the older, 

 ruder, unground weapons till then known as drift implements, 

 and he was the first not only to insist on the difference of their 

 ages, but to show that even the drift implements of the gravel 

 were not all of one age. Then Mr. Christy financed M. Lartet 

 and others to work out the caves of Dordogne, which yielded 

 among other treasures the now celebrated contemporary 

 portrait of the mammoth engraved on his own tusk. 



This then was the state of affairs : — James Geilde and 

 I were up against three problems Avhose inertia was immense. 

 Of course others were in the fray, especially Searles-Wood 

 junior and F. W. Harmer in East AngUa, but I think we two 

 stood most of the blows. Naturally I got a double share, for 

 I had committed the enormity of slighting Bishop L'ssher's 

 chronology, and I assure you the Authorised Edition has the 

 ballistic power of a siege-gun, especially when propelled by 

 Calvanistic cordite. The battle raged on three fronts — the 

 theological, the interglacial, and the Adamic, if I may so put 

 my particular field of action. I should hke to give due credit 

 to others who ^vere in the fray — Mortillet, Rutimeyer, Tidde- 

 man, and many another veteran — but this is not a treatise, 'tis 

 but a bit of personal reminiscence. 



As regards the relics of man, the gravels of France and 

 England had yielded bounteous spoil of implements ; a 

 memorable visit of EngHsh geologists to the Somme had 

 formally received the outcast haches de silex of M. Boucher de 

 Perthes within the pale of humanity ; here is one of the tools 

 brought back by A. Tylor from that memorable meeting. 

 Caves Avere A^ielding up their treasures, and the great fact of 

 man's contemporaneity \A-ith animals now extinct could never 

 more be doubted. Sir John Lubbock was among the first to 

 stress the fact that even in the gravels there was e\ndence of at 

 least two distinct periods, one pertaining to a colder, the other 

 to a warmer, climatic condition.
