Subsequent to the publication of British Barrows in 1877, which recorded the opening of two hundred and thirty-four sepulchral mounds, situated in six counties, all, with the exception of Gloucestershire, in the north of England, I have examined sixty-one in addition. I propose in the following account to give the precise details of the exploration of these barrows, in order that the facts then observed may be put on record, and made available for the use of those interested in this important branch of our native archæology.
