Society. The paper described the subdivisions of the Kimrneridge clay 

 formation, the characteristic fossils by which the separate zones were 

 determined, the comparison of the section exhibited in this, the typical 

 area with the sections occurring in Portland and in the counties of 

 Wiltshire, Oxford, and Buckinghamshire. The author then passed on 

 to describe the chemical composition of the shales, and cement bands and 

 their economic value, and ended by giving the history of the various 

 attempts which have been made to work the beds in Kimmeridge Bay 

 during the present century. Mr. T. B. Groves prepared a paper which 

 described the manufacture of alum from the shales in which it is found 

 particularly those at Kimmeridge Bay at Hoi worth, belonging to the 

 Gault Clay, and at Whitby, in Yorkshire, where they occur in the 

 Liassic series. After this excellent series of papers the time had arrived 

 when the party had to leave Clavell's Tower. A walk of a mile brought 

 them to Kimmeridge village, where they regained the carriages and drove 

 to Corfe Castle rectory. Here they were entertained at tea in the 

 beautiful garden by Mr. Eustace Bankes, and subsequently reached 

 Corfe railway station in time for the 6.47 train after a long and 

 successful day. 



THE BADBURY MEETING. A meeting was held at Badbury Rings 

 and Kingston Lacy on Wednesday, September llth, and again the 

 weather proved all that could be wished. A large party, numbering 

 upwards of 120 members and friends, assembled at the ancient 

 encampment of Badbury Rings about 12 o'clock, some having driven 

 there in their own private carriages, whilst arrangements had been made 

 for conveyances to bring those reaching Wimborne by the various trains. 

 On arriving at the Rings the President conducted the party to the west 

 side, where he pointed out the course of the Roman Via Iceniana, which 

 extended from Yarmouth to Exeter, and crosses the chalk down at this 

 spot. Its course is clearly visible by the ridge or dorsum of the road, 

 which, rising above the general level of the turf, is formed of flints and 

 pebbles from the Woolwich and Reading beds, of which an outlier exists 

 at Badbury. 



At a short distance the course of another Roman Road was pointed out 

 crossing the Via Iceniana almost at right angles. This Roman Road, 

 which had been discovered two summers before and described in Vol. IX. 

 of the " Proceedings," is considered to be of later date than the Via 

 Iceniana, and, in the opinion of the President, was probably constructed 

 for the purpose of transporting minerals from the Mendip Hills to 

 Hamworthy or Poole Harbour, where they would be shipped to the
