§. The lowest sand and stone, occupying 14 feet beneath the 

 quarry-" rock", are stated by the author to contain the same fossils 

 as the calcareous beds above. 



The clay beneath the sand and stone ajjpeared to consist of two 

 principal portions : — the upper, about 34 ft. 6 in. thick, composed 

 chiefly of a sandy greenish-grey clay, which in some places had the 

 properties of fuller's earth ; in this were two thin beds of brown sandy 

 clay, and of clay indurated to the condition of soft stone. 



The lower part of the clay, about 10 ft. 6 in. thick, was greenish- 

 brown, apparently containing more fuller's earth, and becoming 

 darker and more argillaceous as it descended ; at 2 ft. 6 in. from the 

 top of this division Avas a bed, more marly than fuller's earth, and two 

 feet thick, which contained a greater number of fossils. 



§. The fossils from this clay, which had been placed apart, and 

 numbered during the sinking, occurred in the following order, be- 

 ginning at the top : —

to 25 6. Plicatula, Pecten obliquus (interstriatus) , Phola- 

 domya, u.s. ?, Area Raulini, Terebratula, Pletiro- 

 tomaria gigantea. 



31 6 to 34 6. Plicatula, Area Raulini, Pholadomya acuticostatat , 

 Perna Mulleti. 



37 to 39 0. Corbula, and Pinna, numerous; with a Mytilus. 



39 to 49 6, Corbula, Lima, two s^Qci&s,; Niicida, Pinna, Teredo, 

 — the bottom of Cypricardia ?, Venus ?, Ammonites Deshayesii ?, 



this clay. 

 Beneath v.'as the Wealden clay, with Cyclas, small Ostrea and Paludina. 



§. Subjoined to the principal section, are sectional drawings of the 

 Saltwood tunnel, and of a trial shaft sunk near it, illustrating parti- 

 cularly the junction of the upper and middle groups of the lower 

 greensand. The summit of the tunnel is a few feet above the top 

 of the middle group, and there was a constant discharge of water 

 along the line junction, in such quantity as to cause great difliculty 

 in its construction. This middle division, near its upper part, 

 afforded some fine specimens of fossUs, chiefly in ferruginous con- 

 cretions, among which is Nautilus radiatus, with fossil coniferous 

 wood eroded by a Gastrochcenu. Another remarkable product was 

 a new and beautiful fossil resin, found about 10 feet below the junc- 

 tion above-mentioned. A statement of a chemical examination of 

 this substance by Mr. Edward Solly is here given in full : it partakes 

 of the properties of amber and of re tin- asphalt, and is principally 

 marked by its clear red colour, its infusibility, and the difficulty with 

 which it is acted upon by many chemical solvents.
