It is, therefore, certain that in 1622-23, and at some earlier period, some boundaries existed which were sworn to by the witnesses examined by the Commissioners in 1641, and it is probable that these older stones represent two of the earlier boundary marks which were reinstated and again recognised at the last Perambulation. From this point of view the older stones are historically equal in interest and importance to the boundary stones which the Club has been authorised to reinstate in their original sites, and it is, perhaps, hardly necessary to say that in the two cases referred to every care will be taken to preserve both of the adjacent stones. ON SOME UNEXPLORED FIELDS OF ESSEX ARCHAEOLOGY. By JOHN FRENCH. [Read February 29th, 1908.] THE county of Essex has a superiority over many other parts of England in that it contains in its drift deposits relics of human occupation which go back an enormous period in time. It is not possible to assign a length to this period within hundreds, or even thousands, of years. Furthermore, there is not sufficient evidence in the relics that are left to judge of the population by whom they were handled. From whence these people came, how long they remained, and what their occupations were, will for ever remain a mystery. There is one thing that comes out of collating their relics (chipped stones) with those obtained from other countries. This comparison shows that the few types that can be made out had their counterpart in the most distant countries. They are in fact cosmopolitan. There is, moreover, one characteristic of all the implements that were adapted to the hand which, regarded from a mechanician's point of view, is worthy of attention. It is that they were grasped whole-handed, so that when the thrust came upon them it fell on to the muscular part of the hand. All projections were carefully dressed from the base of the implement in preparation for this thrust.
