Miss If. E. J. Gltandler—The Hordle Marine Bed. 227 



of the marine bed as the Upper Freshwater, '' more from position 

 than from its organic contents. Indeed," he adds, " T am not 

 acquainted with any species peculiar to this stratum ; for I have 

 found all . . . in the Lower Freshwater at Hordle." 



If the gentle south-easterly dip of the Headon series prevailed 

 throughout the cliff-section, then the easterly position of the fresh- 

 water beds under discussion would necessitate their being higher in 

 tlie sequence than freshwater beds to the west. But towards 

 Milford the dip decreases, and the beds are all but horizontal ; con- 

 sequently successively higher strata are not brought into the section, 

 and the clays and sands seen are still a part of the Lower Fresh- 

 water series, and, as such, can be traced more or less continuously 

 far to the Avest. 



The next published observations are those of Barbara, Marchioness 

 of Hastings (3). She said that the highest bed of the Lower Headon 

 was 6-8 feet of greyish sand without fossils in the upper part, but 

 about lialf a mile from the point where the bed rises, a narrow dark 

 clay band containing crushed rodent-jaws and bone fragments was 

 seen at its base. Below the dark band there was an incompletely 

 consolidated limestone, 5-10 inches thick, consisting of an 

 agglomeration of Linmaea and Paludina. These beds constituted 

 her division 1 of the series. Her dark band and associated shell 

 marl clearly correspond to the Limnaea I^iiraestone and overlying 

 dark layer with teeth, given in the table on p. 224, column 1, the 

 greyish sands to the thickness of barren sands near Paddy's CTap 

 further east, " where the bed rises." In common with Searles 

 Wood and Wright she evidently regarded +he beds (sands) in the 

 east as higher than those (marls) found in the west, but otherwise 

 the facts that she states are quite in keepmg witli what is now seen. 

 Her second bed is the Marine bed which she states clearly is the 

 lateral (easterly) equivalent of the Limnaea marl and dark clay 

 (part of her bed 1). Her third bed is the purple-grey laminated 

 clay, so that her observations are strictly in accordance with the 

 facts recently noted, though she does not emphasize them and would 

 appear to have missed their probable signilicance. 



The attitude of Tawney and Keeping in 1883 (4) was in large 

 measure responsible for the subsequent disagreements. They began 

 by assuming that the Marine bed was the Middle Marine Headon 

 of the Isle of Wight, and rtiusf, therefore, lie above the whole series 

 of Lower Headon Freshwater beds. Hence the section for which 

 they contended was as follows : —
