lucid account of the geological features of the \arious deposits 

 examined in the cliffs, was passed, and members arrived at Bourne- 

 mouth Pier from Yarmouth about 8.30 p.m. The party numbered 

 28 — three members who omitted to land at Yarmouth were carried 

 round the Island. 



The Oligocene On August 31st an excursion was arranged lo 

 Strata of the Totland Bay, under the direction of Mr. H. St. 

 I. of W. Barbe, of Lymington. Arriving by steamer at 



11.30 a.m., Dr. Ord, with some twenty members, 

 were met by Mr. St. Barbe, who from the pier head gave a brief 

 resume of the coast section there displayed. Proceeding south 

 along the shore the Lower Headon Beds were first examined at 

 Widdick Chine and the base of Headon Hill. Some fine specimens 

 of the thin limestone with Paludina were there obtained. Retrac- 

 ing their steps the party returned to Totland and thence — after a 

 pic-nic lunch — to Warden Point, passing the several sections of 

 the Lower and Middle Headon in ascending order. At Lynchen 

 Chine a remarkable distortion of the strata, consisting of a com- 

 bined thrust fault and anticline was photographed by Mr. Jeffreys, 

 who has kindly presented an enlargement to the Society. Turning 

 inland, an exposure of the Osborne and St. Helen's series was 

 examined and some of the so-called turtles' eggs were 

 found. Descending to the beach at Norton the Bembridge Marls 

 were found, and the excursion terminated at Yarmouth, where a 

 welcome tea was enjoyed. The return to Bournemouth was from 

 Yarmouth Pier at 7.30 p.m. 



Corfe and the The last excursion of the season, on September 

 Purbeck Hills. 21st, was in some respects the most successful. 



Over forty members attended. Dr. Ord con- 

 ducted the party to East Hill, from which a magnificent view was 

 obtained of the Purbeck area, and whence the members looked 

 down upon the remarkable chalk monticle on which Corfe Castle 

 stands. Here an address was delivered by the Chairman on the 

 geology of the district displayed before them, aided by several 

 maps and diagrams. After a pic-nic lunch, the debated subject of 

 the geological origin of the Corfe hill was opened by Dr. Ord, who 

 described several theories, laying special stress on that of the late 

 Mr. Huddleston as the most probable, and which he ventured to 

 supplement as to the mode of the formation of the double gap. 

 An interesting discussion followed, in which Dr. Colley March, 

 Mr. St. Barbe, Captain Elwes, and others took part. After this 

 several pits were visited, the first of curiously hardened chalk 

 gravel, the second showing the junction of the Chalk and Upper 

 Greensand. Proceeding over the brow of the hill, two quarries »n 

 the upper zones of the chalk attracted attention, in which numbers 

 of Calcite Crystals were found. Dr. Ord explained that his atten- 

 tion had been drawn to these by Mr. Carus Wilson, and that they
