6. — Asplenium Ruta inuraria: not very common^ Lut occurring on walls 

 at Torrj and Culross church. 



7. — Asplenium Tricho manes: common, 



8. — Athyrium filix-foemina: common in clamp shady woods^ as at Valley- 

 field. 



9. — Polystichum lohatum: abundant in shady woods in all parts of the 

 district. 



10. — Lastrea spinulosa: common in similar situations to the last. 



11. — Ladrea Jilix-mas: very abundant. 



12. — Cystopterin frcKjilis: rare, but growing in great perfection on Culross 

 church, along with Asplenium adiuntum-niyrum and Asplenium Huta-murana. 



13. — Poll/podium valgare: plentiful in several places in the vicinity; 

 Valleyfield, Culross. Very fine in the Ladies' Walk, Culross Abbey, and 

 on a bank at the Abbey Park there. 



14. — Poh/podium Dryopteris: discovered by Mr. Kirk, growing in the avenue 

 leading to Valleyfield House, in considerable abundance, along with BlecJinum 

 boieale, {Lnmaria spicant of authors,) and Lastrea Jilix-mas^ Athyrium jUix- 

 fcemina, and Polypodiwn vulgare. 



15. — Osmunda reyalis: this x'are Fern in the east of Scotland, though found 

 plentifully on the banks of the Clyde in the west, grows in considerable 

 abundance in a small field on the sea-shore, between Culross and Kincardine, 

 near Blair; but I have never succeeded in finding it in fruit. 



16. — Ophioglossum vuhjatum: this beautiful plant exists plentifully in a 

 small wood above Tainianu, Torry, and also in another damp shady plantation 

 on th3 same ^tate; in both places in considerable abundance,

ON SOME OF THE 



MODERN GEOLOGICAL CHANGES EXHIBITED IN THE 



NEIGHBOURHOOD OF GLASGOW. 



BY W. FERGUSON, ESQ. 

 ( Continued from page 78.^ 



In addition to the proofs of an ancient higher sea-level arising from the appear- 

 ance of these terraces, which of itself would lead us to the supposition that 

 they had been formed by the action of waves, we have the authentic records 

 of the discovery of shells in the clays and sands, of which many of them are 

 composed. Thus at various points in the parishes of Paisley and Renfrew, 

 have shells been found, especially at Oakshaw and Bellahouston. They have 

 been found in some of the brick-fields at Annfield, by Mr. John Craig, and 

 by the same person in various other places, at forty, eighty, one hundred, 

 and three hundred and sixty feet above the sea-level. Shells were discovered
