OF HARTING. 9 



and they are in parts so fine and incoherent, and of 

 so purely white a colour, as to be used by ladies in 

 washing. In a recent cutting of the railroad from 

 Petersfield to Midhurst, which passes by the north 

 side of West Heath, a rich argillaceous ironstone, 

 found by Mr. Buxton, exhibited on its surface small 

 circular cavities in pairs, evidently the work of a marine 

 worm or annelid, together with casts of, probably, the 

 remains of seaweeds. In many other places the fer- 

 ruginous structure of this band is very conspicuous. 

 This is well seen on the side of the road from Peters- 

 field to Midhurst, particularly to the east of the latter 

 town, where the ironsand assumes singular concre- 

 tionary forms. Where the black oxyde of iron pre- 

 vails, the stone found in this layer rings under the 

 hammer, and is the clinkstone used in road making. 



It is on the western termination of this ferruginous 

 portion of the Lower Greensand that the town of 

 Petersfield stands. There the geologist has only to 

 explore southwards to Butser Hill, or northwards to 

 the Froxfield Hangers, and he passes successively up- 

 wards over all the formations I have enumerated to 

 the Chalk with Flints inclusive ; the pointed mass of 

 sandstone at Petersfield being wrapped round to the 

 north-west and north by the confluence of the younger 

 formations of the Gault, Upper Greensand, and Chalk. 



The fossils of this upper band of the Lower Green- 

 sand are not numerous hereabouts. In other tracts, 

 as at Parham Park, the following are characteristic 

 two or three of them, however, were found by 

 me many years ago on the commons north of Peters- 

 field : Gervillia acuta, Trigonia alaeformis, Cytherea 

 (Venus) parva, Panopsea plicata, Cucullsea decussata, 

 Thetis Sowerbii, Modiola aequalis, Tellina sequalis, 

 Cyprina angulata, Rostellaria Parkinsonii, Ammonites 

 dentatus. 



Though not exhibited in this neighbourhood, the 

 calcareous conglomerate called Bargate Stone, occa- 

 sionally burnt for lime, and abundant near Godalming,
