about a dozen — who braved the elements went by train to 

 Lymington, crossing thence to Yarmouth. Mr. G. Colenutt, f.g.s., 

 of Ryde, had arranged to meet the party there, but as he was 

 unable to come, Dr. Ord conducted the excursion. Mr. Colenutt 

 kindly sent some diagrams illustrating the arrangement of strata in 

 the cliffs, which were distributed to members and proved a useful 

 guide. Driving to Freshwater and thence along the military road 

 to a point over Compton Bay, the path to the beach was descended. 

 The junction of the Chalk and Greensand was observed, and the 

 Chairman gave some account of the geology of that portion of the 

 coast. Owing to the very high tide and gale, it was impossible to 

 proceed any distance along the beach, and the intended visit to 

 Brook and the submerged forest had to be abandoned. A few 

 fossils from the chalk were obtained. 



. The Oxford University Extension Lecturer, the 



DurlstonBa Rev> E ' C * S P icer ' M - A " F<G - S -' had inten ded 

 y * arranging a geological excursion, to which all who 

 had attended his lectures on the "Science of Scenery" should be 

 invited. As he was unfortunately unable to arrange this, Dr. Ord 

 was asked to conduct one or two excursions to illustrate by nature 

 study the principles so ably set forth in the lecture-course. At the 

 request of the Bournemouth Students' Association, this was 

 arranged, in conjunction with the Geological Section of the Bourne- 

 mouth Natural Science Society. To this all others who had 

 attended the preceding lectures and classes were also invited, the 

 combined excursion being conducted by Dr. Ord to Durlston Bay 

 on May 10th, 191 1. Some forty members and friends attended the 

 excursion, which was a great success and proved of much interest. 



Leaving Bournemouth Pier by the 11.45 a.m. boat for 

 Swanage, the great Purbeck thrust fault in the cliffs at Ballard 

 Down was observed en route, and after landing at Swanage Pier the 

 party walked to Peveril Point, where lunch was enjoyed on the 

 grassy slopes. After this Dr. Ord gave an address on the coast 

 scenery around them, pointing out their position relatively to the 

 Hampshire basin, the chalk ridge of the Purbeck Hills, a few miles 

 to the north, forming the southern boundary of the basin in its 

 western extension. The special features of the Purbeck beds, 

 which they were about to examine, were then described, and illus- 

 trated by reference to a large diagram. After this address, which 

 was listened to with much interest and attention, Dr. Ord took the 

 party down the steps to the beach. The first objects noted were the 

 two reefs of Upper Purbeck rocks (the celebrated pink and grey 

 Paludina marble) stretching out to sea, and the curious double 

 anticlinal fold, which has enabled them to resist wave-action. Next 

 the Unto beds were found, also the curious layer of vertical lime 

 crystals known as beef. Further along the Mammal bed was pointed 

 out, which had yielded — in another part of the cliff — some remains 

 of one of the earliest known mammals, a little marsupial, about the 

 size of a rat. The Cinder bed, a real fossil oyster bed, excited 

 much interest. Two small faults were noted and explained, and
