ABSTRACT
The immediate origin of the round-headed invaders has been determined once and for all by Abercromby from a masterly study of the characteristic pottery-the Beakers-deposited in their graves. His paper,3 published in 1902, really marks the beginning of a new era in British archaeology, and his general account still holds good. Nevertheless thirty years researches have inevitably entailed certain modifications in the results of such pioneer studies. Abercromby 4 envisaged a single group of invaders, landing at one point in South-East England and thence overrunning the whole country. To-day it is generally admitted that independent landings may have taken place at several points along the east coast of Scotland as well as of England.
