APPENDIX. 405 



Another curious point illustrated by Davvkins, with the 

 aid of the recent re-discovery of the tin-miues of Tuscany, 

 is the connection of the Etruscans with the introduction of 

 the bronze age into central Europe. This, when viewed 

 in relation to the probable ethnic affinities of the Etruscans 

 with the " Neolithic " and Iberian races, remarkably welds 

 together the stone and bronze ages in Europe, and explains 

 their intermixture and " overlap " in the earlier lake habi- 

 tations of Switzerland and elsewhere. 



A still more important speculation, arising from the facts 

 recently developed as to pre-historic men, is the possible 

 equivalency with the historical deluge of the great sub- 

 sidence which closed the residence of paleocosmic men in 

 Europe, as well as that of several of the large mammalia. 

 Lenormant and others have shown that the wide and 

 ancient acceptance of the tradition of the Deluge among all 

 the great branches of the human family necessitates the 

 belief that, independently of the Biblical history, this great 

 event must be accepted as an historical fact which very 

 deeply impressed itself upon the minds of all the early 

 nations. Now, if the Deluge is to be accepted as historical, 

 and if a similar break interrupts the geological history of 

 man, separating extinct races from those which still sur- 

 vive, why may we not correlate the two ? The misuse of 

 the Deluge in the early history of geology, in employing it 

 to account for changes that took place long before the 

 advent of man, certainly should not cause us to neglect 

 its legitimate uses, when these arise in the progress of 

 investigation. It is evident that if this correlation be 

 accepted as probable, it must modify many views now held 

 as to the antiquity of man. Irt that case, the modern 

 gravel and loess, on plateaus and in river valleys, far above 

 the reach of the present floods, may be accounted for, not 

 by the ordinary action of the existing streams, but by 

 the abnormal action of currents of water diluvial in their
