30 Stone Implements from neighbourhood of Chelmsford. horns were found near by in the soil, tending to show that the ground might have been disturbed; and we have also to take into consideration the possibility of the man having made a mistake in determining the spot from whence the implement fell. [As Mr. Corder's celt is a very beautiful example of a type by no means common, a figure is given of it, showing the front and side views. The specimen has been seen by Major- General Pitt-Rivers and by Mr. Worthington Smith.—Ed.] I also exhibit a hammer-head made of an oval mass of sandstone, such as abound in our Glacial deposits. It is five inches long by three and a half wide, and has a hole apparently bored from both sides, as it slopes, crater-wise, from both surfaces to the middle. The ends of the stone give evidences of use, showing numerous slight chippings and irregularities. It was found in a yard at Writtle, Essex, having apparently been brought there from the fields with other stones for paving purposes. The third small flint I exhibit was found near Chignal, Essex, by Mr. R. M. Christy, a member of the Club. It is three inches long and three-fourths of an inch wide. One side is polished, the other roughly chipped, and the stone tapers towards each end. The use to which it could have been put I do not know, but perhaps it may have been used as a polishing implement in dressing other stones.
