tine lines. Some other fossils belonging to these beds are 

 occasionally found in the neighbourhood; they consist of 

 Trochi, two species of Echini, teeth, palates and fragments of 

 fishes. 



The sea-water has the effect of hardening this rock ; that 

 part of it which is daily covered by the sea is much harder 

 than that which is dug in the pits in the country around. 



No. 4. H foot. A stratum of white chalk, more loose than 

 the last, containing no fossil shells, yet is disthiguished by a 

 remarkable species of ramifying zoophyte, resembling the 

 roots of trees ; about an inch thick, branching and interweav- 

 ing in every direction. Some of the fi'agments are not unlike 

 the horns of a stag. 



No. 5. ^ foot. An intermediate vein or seam between the 

 white and the red chalk, varying from one to six inches in 

 thickness ; of a soft substance and of a deep red colour, sup- 

 plying, probably, the colouring matter of the two succeeding 

 strata. 



Several small springs of water issue out, at the eastern ter- 

 mination of the cliffy from between the beds of white and red 

 chalk. No. 4 and 6 in this situation. 



No. 6. 2 feet. Red chalk, of a rough disjointed structure, 

 similar, except in colour, to No. 4, and, like it, though in a 

 smaller degree, interwoven with the ramifying zoophytes be- 

 fore mentioned. It contains three or four species of Terebra- 

 tula, smooth and plicated, T. bijjlicata and intermedia ; a vast 

 number of fragments of Inocerami, and numerous specimens 

 of small, fusiform, slender, and almost translucent Belemnitcs, 

 besides small siliceous semitransparent pebbles. 



No. 7. 2 feet. A more compact stratum than No. 6, of a 

 darker red chalk, contains more siliceous pebbles and fewer 

 organic remains. Those most observable are Tcrehratula 

 and Bclemnites. It \'aries in its degrees of hardness, being in 

 some parts very loose and crumbly, but for the most part 

 equally hard with the strata above. 



No. 8. 10 feet. A sandy ferruginous stratum; in some 

 places possessing all the properties of stone, and adapted for 

 building ; and in others very soft. It is of a light brown co- 

 lour, stratified, with vertical clefts or fissures passing into the 

 stratum beneath. It contains no fossils, but some pyrites may 

 be collected. It was probably in this stratum that Mr. Aikin 

 discovered a magnetic iron ore, described as containing eighty- 

 five parts oxide of iron and fourteen of oxide of titanium. 

 Colour dark ; iron black. Occurs in loose octahedral cry- 

 stals, or in small roundish and angular grains ; fracture con- 

 choidal, rarely exhibiting any traits of lamellar structure :
