* It may be useful to point out in what particulars the present memoir differs from its prede- 

 cessor, which was read June 4, 1830, reference being had to the Table of contents in the Memoir. 

 The delay in finally preparing the paper has arisen from the Author's stay in Mexico and the United 

 States from 1831 to 1834. 



In §§. 1 to 6, the Introductory part and general distribution of the subject have been remodelled 

 in some respects. 



In §§. 7 to 20, the disposition, mineral characters, and organic remains of the greywacke and 

 slate series stand nearly as before. 



In §§. 21 to 33, the details of the disposition, characters, and organic remains of the transition 

 limestone are new for the greater part. 



In §§. 34 to 46, the metalliferous relations of the transition tract are much condensed, but in 

 other respects as before. 



In §§. 47 to 68, the detailed disposition, characters, and organic remains of the South Munster 

 carboniferous series are almost entirely new. 



In §§. 69 to 75, the same may be said of the North Munster carboniferous series, with the ex- 

 ception of the " coal formation" (§§. 71 to 75.), which stands nearly as before. 



In §§. 76 to 83, the metalliferous relations of the carboniferous series are mostly new; and 

 partly also §. 84, on segregated metallic deposits in general. 



In §§. 85 to 89, the notices of Diluvial Action have been amplified to a certain extent, and ren- 

 dered more general with respect to Ireland.
