The purpose of this paper is to describe and figure eight palæolithic flint implements discovered in the Cannon-shot gravel of Norfolk. The specimens were found during researches carried out under a grant from the Percy Sladen Trustees, to whom I am much indebted for their help. I have also to acknowledge the assistance given me by Mr. G. Maynard and Mr. J. E. Sainty, who have been intimately associated with my investigations.The Cannon-shot gravel derives its name from its contained rounded and battered flint pebbles, symmetrically shaped like the cannon-balls in use at the time when Wood and Harmer first examined it. This gravel is well-known to geologists, and extends over large areas in Norfolk. It often occupies high ground, and can be examined in the cliff sections along the north-east coast of this county, and also in many inland pits. The gravel, wnich contains an appreciable number of foreign rocks, usually presents little evidence of stratification, though horizontal and thin layers of sand and loam are to be observed in its mass. The contained stones often rest in a vertical or inclined position in the gravel, a fact which makes it difficult to believe that water-action of the normal kind was responsible for the laying down of the deposit.
