APPENDIX A.— p. 260. 



The tabular chart referred to in the Memoir, represents, at one view, all the workable coal-seams 

 and limestone strata in East-Lothian and Mid-Lothian, the names of the places where they are known 

 to exist, with their thicknesses and mutual vertical distances at these places. 



The first column in the table, is occupied with a list of the coal-seams and limestone strata, arranged 

 in the order occupied by them in a supposed section of the basin, from top to bottom. Where the coal- 

 seams are known by particular names, these names are stated, — with such a distinguishing mark as to 

 shew the place where this appellation obtains. This first column consists of seventy-three lines, of which 

 sixty-six are occupied by coal-seams, and seven by limestone strata. 



_ The other columns in the table are devoted to a statement of the thicknesses in feet and inches, and 

 the mutual distances in fathoms and feet, — of the strata mentioned in the first column, at various places 

 specified in these columns. 



The structure of the table will, however, be best understood, by making fi'ora it a few extracts ; and 

 these will be so chosen, as to illustrate and verify the statements in the text.
