of Hordwell, Hampshire. 5 



in the sandy seams layers of Uniones, Paludince, and seeds which 

 are very perfect, and flake off in large masses. At the base of 

 the stratum, at about half of its length, is a small layer of Limnea 

 and Cyclas, which only extends about 2 yards in length, and is 

 rare to find uncovered. Pebbles of pyrites, from which vitriol 

 is procured, are found at intervals in this bed. There are no 

 remains of Trionyx, Emys, or Crocodile found here. 



Stratum 5 averages from 4 to 6. feet, and is a very well 

 marked and interesting bed. It can be traced for a very long 

 distance in the cliff; and in clear weather with a glass, I have 

 seen it when many miles off at sea. It commences with a very 

 narrow band (about an inch) of lignite. After this there is a 

 band of gray sand of from a foot to 18 inches thick, with no 

 fossils. Then there is a band of dark gray clay, containing 

 seams of lignite of 18 inches, resting on these seams; in the 

 clay are found Paludina. This stratum ends with 18 inches of 

 gray sand, very variable as to darkness. The first 6 inches 

 under the clay and lignite contain layers of Uniones, Paludina, 

 Potamomyce and lignite, Limnea and Melanopsis brevis, occa- 

 sionally but rarely the Potamides cinctus, with seeds of Charge and 

 broken portions of the carapace and plastron of Trionyx. No 

 other animal remains are found here. The same small layer of 

 Cyrena cycladiformis and Limnea fusiformis and arenaria which 

 occurs at the base of No. 4, occurs here also for the space of about 

 3 yards. This is the last stratum in which Unio Solandri is 

 found. 



Stratum 6 averages from 15 to 20 feet in depth. It consists 

 entirely of blue mottled marl coloured with iron, and a vein of 

 lignite not more than an inch in thickness running through the 

 bed nearly at the middle. It is utterly barren as to fossils, 

 except specimens of Paludina lenta, which are very rarely met 

 with. 



Stratum 7 averages from 4 to 6 feet. It commences with a 

 very narrow band of lignite, resting upon about 3 feet of green 

 marl slightly mottled and covered by iron. After this there is 

 a small band of lignite of about 6 inches, which only comes in 

 occasionally, and under it a band of sand of about 8 inches, 

 which also sometimes disappears; after this about 18 inches 

 or 2 feet of green clay mottled with iron. The whole stratum 

 is barren as to fossils. 



Stratum 8 is small, varying from 3 to 10 inches of Limnean 

 limestone, composed apparently chiefly of crushed and broken 

 Limnea and Planorbis rotundatus ; occasionally, but very rarely, 

 a perfect specimen of either of these is found, but no other shells 

 and no animal remains; no fish or seeds are found here. When 

 this stratum is first uncovered, it is in a perfectly hard state, but
