Mr. T. Codrington, F.G.S., notes that " Fragments of Sarsen or 

 Grey wether Sandstone are met with everywhere [in the Hampshire 

 gravel] , and blocks of considerable size are found in the gravel of 

 the cliffs between Southampton Water and Gosport, and near 

 Southampton, at 170 feet above the sea. A block of puddingstone 

 . is stated to have come from the gravel of Hordwell 

 Cliff." Quart. Journ. Geol. Soc., vol. xxvi., 1870, p. 535. 



In the Wilts Mag. (No. 33, February, 1869), vol. xi., p. 348, 

 Mr. W. Cunnington stated of one of the imposts of the outer 

 circle of Stonehenge (the only one remaining in situ towards the 

 north-west), near the trilithon that fell in 1797 — its " upper portion 

 to the depth of a few inches, consists of a conglomerate of flints and 

 sand/'' " Masses of Sarsen made up entirely ol a similar conglomerate 

 of chalk-flints frequently occur in the neighbourhood of Standen, 

 near Hungerford, but they are not found in the middle or southern 

 districts of Wilts/' W. C[unnington] . 



One such, but much worn, pudding-stone was found by Messrs. 

 H. Nevil Story Maskelyne and W. Cunnington on Barbury Down in 

 August, 1886. It is perforated by rootlet pipes between the pebbles 

 from one face to another. 



In the chapter on Erratic Blocks in his " Geology of the S. E. 

 of England," 1833, pp. 48 — 50, Dr. Mantell noticed the occurrence 

 of both " blocks " and " boulders " of the Grey wether or Druid 

 Sandstone (sometimes containing flints l ) on the Sussex Downs ; 

 and many much-worn boulders he observed in the old shingle-bed 

 or " raised beach " at Brighton. He adds : — " Upon comparing the 

 sandstone of Stonehenge with that of Sussex no perceptible differ- 

 ence can be detected ; and in this County, as in Wiltshire, they 

 have been employed by earlier inhabitants as landmarks to denote 

 the boundaries of towns and villages, or to commemorate the site 

 of battles, — as sepulchral stones, to perpetuate the memory of their 

 chiefs, — and as altars on which to sacrifice to their gods." A 

 Sarsen " placed at the corner of Ireland's Lane, in St. Ann's parish, 

 forms the western boundary of the Borough of Lewes/' 



1 " The small fragments of a dark-green substance " referred to by Mantell as 

 occurring in this sandstone may possibly be glauconite.
