 Mr. Knowles' collection, identified as JElephas, and found in the 

 railway section, l^o significance can be attached to these remains as 

 regards the age of the gravels. They must be regarded as derived 

 from an older formation, as in the case of the Mammoth tooth found 

 at Eallyrudder, in the Larne locality, and now in the Grainger 

 collection, Belfast.

COIlRELA.TIOi^ OF CHANGES OF LEVEL WITH HUMAN 



PEPIODS. 



Having dealt thus far with the geological history of the district 

 and the character and relative age of its Neolithic remains, we may 

 now return to our original position, and point out the bearing of these 

 considerations on the question of the Broighter gold ornaments, and on 

 the general history of the district in post-Glacial times. 



The gold ornaments found at Broighter were ploughed out of stiff 

 clay on the shelf or raised beach which we have discussed, at a point 

 where the height above ordinary high water is 4 feet. We have seen 

 that the top of the marine series at Larne has been elevated to a height 

 of no less than 22 feet above high water, and also that the amount of 

 elevation increases northward in Ireland. It follows that the emer- 

 gence of Broighter from the waters of Lough Foyle took place almost 

 at the close of the movement of elevation. The point to be, if possible, 

 decided was, at what period did the emergence of Broighter take place ? 



Evidence from Larne. 



The Larne raised beach proves that practically the whole move- 

 ment of depression, as represented by the series there, took place 

 during Neolithic times. The lowest beds, up to the top of the 

 estuarine clay, have so far furnished no evidence. But the whole of 

 the overlying 19 feet of gravels yield flints of human workmanship, 

 showing that man was on the ground during the submergence that 

 allowed of the continued laying down of this mass of material in
