^{page 29 note c} It may, perhaps, be considered in some degree confirmatory of this assumption, that the church in the adjoining village of Southese (which has a round tower exactly resembling that of Piddinghoe, and of the same date) was discovered, in 1851, to stand on the site of an ancient tumulus.—Sussex Archæological Collections, v. 205.

^{page 34 note a} Since the above was written, Mr. John Evans, who spent a few weeks at Seaford during the autumn of 1867, and who had therefore greater opportunities of carefully examining this work, has informed me that he found a scraper and a few flakes within the fort.

^{page 40 note a} Since writing the above, my attention has been drawn by Mr. Boyd Dawkins to the evidence of an extensive flint manufacture which exists in the neighbourhood of Hollingbury, and which leaves little doubt on my mind that this work, like the others, was of British origin.

^{page 41 note a} Since writing the above I have ascertained that the interior of this work has been extensively dug for flints.

^{page 44 note a} After a second visit to this place, and from information kindly afforded me by Mr. Goring, on whose property the fort stands, I have come to the conclusion that this must be an ancient well, probably constructed by the Romans, coins of which people, of a late date, were found in great numbers when planting the inclosure. During the excavations I also found Roman tiles in the advanced circles. The water supply for the original British intrenchment was probably obtained from a good spring about a quarter of a mile distant, at the foot of the hill to the north-east, to which spot there is an ancient roadway, which, like that of Ditchling, has a rampart thrown up on the side of the valley. It runs obliquely down the hill from the fort to the spring.

^{page 48 note a} There were earth-works at Soraers Town called The Brill, which Stukeley considered to be Roman, though Lysons (Environs of London, iii. 343) very strongly opposes this opinion. The coincidence of the name is in any case worth remark.
