The implements shown were found in Heacham Park while digging an ornamental lake in February, 1914. The tanged and barbed arrow-head of ruddy-brown flint, not lustrous, 1¾ in, long and ⅝ in. wide at the barbs, was found within a foot of the surface just below the turf. The others (Aurignacian, according to Mr. Reginald Smith) range in colour from blue-black to cream, and include a cream scraper, 2½ in. by 1½ in.; a flake, 4¾ in. by 1¼ in.; and an implement with traces of fire (Plate CXXII.).

The section was as follows:—(1) 7–8 in brown peaty earth with roots, and at base chalky concretions of marl, scaling; 1 in. in diameter and less (brown arrpw-head here). This, graduates through (la) 2 in. a grey marly earth or clay, to (2) 8-in. white chalky clay, granular to sight after passage of spade, yet clayey to touch.

The discovery to which this paper refers was made by a series of very fortunate circumstances. A resident in Ivry Street, in the northern portion of Ipswich, was having an inspection pit sunk for his motor car, and during the excavation his gardener, who is familiar with humanly-worked flints, found a number of long flakes at a depth of about three feet from the surface of the ground. These he fortunately preserved and gave to my workman Baxter; who brought them to me.

I at once paid a visit to the site and, owing to the kindness of Mr. Makepeace, the occupant of the house in Ivry Street, was enabled to conduct a series of excavations and to find the various specimens which it is my purpose to describe.

In continuation of my former review of advances made in recent years in the science of palethnology, it seems to me that, in view of the rapidity with which our knowledge of this subject has increased during the last eighteen months or so, it will be opportune and acceptable to once more put before prehistorians a summary of this newly-acquired knowledge, and to point out the great interest and importance of the discoveries which have made that knowledge possible.

I must confess to a certain amount of satisfaction in recognising that some of the forecasts of future, discoveries which I foreshadowed in my former article have in some measure been fulfilled, while some of the lines of research which I suggested might be followed up have been investigated and are in process of partial solution. One of the most important of these, the investigation into the causes and meaning of the “patination” of flint, was worked at by the late Dr. Canton, of Ipswich, who carried through a series of highly interesting experiments in which flints were subjected to the action of various solvents, and it is my hope that some account of this work will be laid before the scientific world in the near future.
