THE account given in this week's NATURE (p. 518) of the discovery of a prehistoric burial-ground at Pitreavie has recalled to my memory the description of a similar find made in the eleventh or twelfth century by the monks of Noyon, and related to us us by Guibert, who was abbot of this foundation at the time. I believe that it is the earliest detailed account of any such discovery that has come down to our days; and it will be noticed that the leading features of this cemetery are almost exactly identical with those of the Pitreavie one. I am not aware that this passage has attracted the attention of modern writers upon prehistoric times.
