They are iden-tical in those features with neolithic flakeswith which they were found at Ickling-ham, Suffolk. There is thus evidence ofthe occurrence of rostro-carinate flintimplements in deposits of several suc-cessive ages, and it may be brieflystated here that the rostro-carinates havedistinctive characters of form and work-manship in each horizon do not appear to be derivatives inthe later from earlier deposits, as theyare not water-worn and have in each casea distinctive patina. On the otherhand, I have seen three ivater-ivorn specimens of rostro-carinates which were foundin river-terrace gravels, and have been at once recognized as derived from Fig. 14.—View of the ventral plane of theMacgee specimen.

I have no doubt,from the comparison of its very peculiar dirk colouring and characteristic lustre with that of the Hints from the stone-bed at Whitlingham (nearly all of which arefractured and of large average size, not pebbles ), where it was found, that it cameout of that bed. The bed rests on the chalk. Above it there is light yellow-brownXorwich Crag with shells; above that we have paler coloured mid-glacial sands,thirty feet thick. The flints in the
