The bones of man have not at present been certainly found in the Palaeolithic deposits of the Thames valley ; man is only known to have lived in company with the animals above enumerated by his works in the shape of the well-known and beautifully made imple- ments of stone. A fragment of human skull (see Essex Naturalist, p. 45 ante) has, however, been found near the northern border of Essex, 7 1/2 feet in brick earth, by the side of the high road from Bury St. Edmunds to Saxham, in Suffolk. The discovery was made by Mr. Henry Prigg, M.A.I., and is recorded on the "Journal of the Anthropological Institute" vol. xiv., p. 51 (1884—5). Mr. Prigg says he thinks there can be no question as to the great antiquity of the fragment, and that the deposit of red loam in which it was found must have been formed long anterior to the complete excavation of the valley of the Linnet to the south. It was found in a "pocket" eroded in the chalk. In adjoining "pockets" two grinders of the Mammoth were found, and four Palaeolithic implements. By the courtesy of Mr. Prigg, I am enabled to print an illustration of the skull fragment (fig. 16) engraved one-half the actual size from nature by myself. It consists of a portion of a frontal bone, about five inches of the coronal suture, and a little over two inches of the sagittal with the anterior third of the left parietal, and a small portion of the right. The thickest part of the bone is three-tenths of an inch. Mr. Prigg considers the fragment to have belonged to "an undersized,
