far too intricate a question to be passed over, although without doubt the fluvio- 

 luarine strata of the Hampshire basin will ere long receive critical supervision with 

 reference to similar deposits on the Continent. So far back as December 18G3, 

 Ilevr Adolf Von Kunen read his paper on the correlation of the Oligocene de- 

 posits of Belo'ium, North German}-, and the South of England, and endeavoured 

 to show that in Britain we had an assemblage of fossils in our so-called Middle 

 Eocene at Brockenhurst, Lyndhurst, and Roydon in the New Forest, that could be 

 stratigraphically correlated with beds of the same age termed Oligocene in Northern 

 German}^ The author believed that these Brockenhurst beds were of the same 

 age as the Middle TIeadon beds of Colwell Bay and Wliiteeliff Ba}'. This view 

 has led to much controversy, arising from the fact that no Brockenhurst species 

 occur in Colwell Bay. The rich cabinet of Mr. F. Edwards theu atibrded Von 

 KiJiien every facility for the comparison and determination of the species occurring 

 common to Britain and Germany. Beyrich established the name Oligocene for the 

 fossils of this age in Germanj'. The Lower Oligocene is well-developed, with a true 

 marine fauna, in Belgium near Tongres (N. of Liege) and in the N. of Germany 

 between Magdeburg, Bernberg, Egelu, and Helmstiidt (near Brunswick). This 

 Lower Oligocene contains 700 species of moUusca besides other groups. The most 

 characteristic of these the author asserts are found at Brockenhurst, and in Mr. 

 Edwards's cabinet fifty-si.x species occur, twenty-one of which are Barton clay forms, 

 and forty-three of the fifty-six species occur in the Lower Oligocene of Germany.

1. Notes relating to some of the Drift Phenome7i a of HampsJiire : 1. Boulders, 

 Hayling Island ; 2. Chert Debris in the Hampshire Gravel ; 3. Elephant 

 Bed, Freshwater Gate. By Professor Prestwich, M.A., F.B.S., F.G.S. 



In this paper the author draws attention to a few points which have either 

 escaped notice or on which he would put a different construction. 1. The remark- 

 able boulders of crystalline and other old rocks of Pagham were noticed long 

 ago by Mr. Dixon and Mr. Godwin-Austen ; and Mi-. Codrington has more recently 

 described similar boulders in the gravel of Portsea Tsland. Those of Hayling 

 Island have not yet been noticed ; nevertheless they are very numerous. The 

 author describes two of (p-anite and three of srindsfone of large size on the shore near 

 the railway station, and" states that he counted thirty smaller ones in a mile to the 

 westward of the station. The greater number, however, of those on the shore facing 

 South Hayling village seem to have been collected to form rockwork in the Grotto 

 grounds and in the grounds of "\^'estfield House. Amongst them are boulders of 

 i/ranite, syenite, porphijrii, slate, ?a\i\ sandstone. They are found scattered in lesser 

 numbers all over the island, embedded in the flint gravel and loam which overlies 

 the London clay. ]Mr. God win- Austen considered that the Sussex boulders might 

 be derived from an old coast now submerged in the area of the Britisli Channel, 

 but the author sees reason to believe that they are more probably derived from 

 the coast of Devon and Cornwall. A large fragment of silicified Portland wood has 

 been described by the Rev. 0. Fisher from Pagham, and the author saw in Hayling 

 Island a piece above two feet in length of well-characterised Portland wood. 

 The granites and other rocks, tliough not yet determined, seem to resemble West of 

 England rocks, and he saw none of the characteristic granite of Cherbourg 

 amongst the Ijoulders. Further, the author found at Stubbington Cliff and Hill 

 Head numerous quart zite pebbles similar to those of the Budleigh conglomerate. 

 He concludes therefore that the boulders were carried here by ice at the time 

 of the old Raised Beach of Brighton, Portland, and the Devon coast, and that their 

 absence in the intermediate area is due to the destruction of the beach and the 

 wear back of the old coast line, except at a few spots where, with remnants of 

 the beach, the boulders have been preserved.
