In the course of my work on Jade Axes from sites in the British Isles (PPS, XXIX, p. 133) I had occasion to consult descriptions of jade axes from Europe and to make notes on all those in publications available to me. I have now plotted on an outline map of Europe (fig. 1) the sites of recorded jade axes and have added also the locations of the few jade axes from France in the British Museum, Ashmolean Museum, and in the Wellcome Historical Medical Museum, which I have examined.
This map is far less complete than that showing the distribution of jade axes in the British Isles, op. cit., fig. 4, which shows the location of every jade axe known in museums or in private hands as well as a few mentioned in the literature but not traced.
The new records of British axes, recorded at the end of this paper, have been shown on the outline of the British Isles, included on the present map which reveals a large increase in the concentration in East Anglia.
As regards Europe, apart from the few jade axes from France mentioned above, the records plotted are confined to those known to me from publications and I have had to rely on the authors' identifications of the materials used. These are confirmed by density determinations for a great many of the axes from Germany and for a few of those from Italy.
