568 to me by Canon Greenwell, F.R.S., was procured from a Lakenheath workman, but it is not certain whether it was found in the gravel near that place, or in one of the pits near Brandon. It differs from all other implements that I have seen from the River-drift, in having an oblique hatchet-like edge at the end, so that the side-view somewhat resembles that of the iron Francisca of Saxon times. A considerable portion of the original crust of the flint remains at the butt-end. Until other specimens of the same form are discovered, it is hardly safe to regard this as furnishing an example of a new type of implement; yet its symmetry and character seem to prove that it was designedly chipped into this form, to fulfil some special purpose.

It will be best to postpone any remarks as to the probable connection of the beds near Lakenheath with the ancient course of the Lark and Little Ouse, until I come to consider the geological aspects of the whole case.

It was from a place called Botany Bay, near Brandon, that Mr. S. B. J. Skertchly, F.G.S., of the Geological Survey, first obtained evidence on which he founded the existence of the beds that he termed Brandon Beds, which though containing palæolithic implements he regarded as occurring below the Chalky Boulder-clay, and as, therefore, of Interglacial date. The evidence that the implement-bearing beds are, at all events in the Eastern Counties, later than the Boulder Clay is now beyond all cavil, and, so far as I could judge, the supposed Boulder Clay lying above the implement bed at Botany Bay was not in its original position, but was either remanié or had slipped down from a higher level. It is, however, but fair to state that the Rev. O. Fisher, F.G.S., has accepted Mr. Skertchly's views, at all events with regard to some of the localities, as to there having been three successive Palæolithic Periods in Britain, each preceded and succeeded by a Glacial Period. I can only say that I am not prepared to accept such a view.

I must now proceed to describe another of the River-drift deposits in the more immediate neighbourhood of the Little Ouse, and lower down its course, at Shrub Hill, in the parish of Feltwell, Norfolk.

This too has been described by Mr. Flower in the paper to which I have already so frequently referred. It has also been described by Mr. H. Trigg, to whom flakes from this deposit were
