Introduction. — Little or no attention has been paid to the organic 

 remains of the great series of strata below the Gilmerton or No. 1 

 Limestone of the Midlothian coal-field (adopted as the conventional 

 base of the Carboniferous Limestone series by the Geological Survey \ 

 when compared with the numerous papers and other publications 

 bearing on the fossils of the overlying strata or Carboniferous Lime- 

 stone Series. It is true the fishes were examined by Agassiz*, 

 and the plants to some extent by Lindley and Hutton, but in 

 both cases only to a limited extent. Dr. Hibbert's celebrated paper 

 on the Burdiehouse Limestone appears to have been the first memoir 

 in which any systematic observations were recorded; and, with the 

 exception of a few miscellaneous publications in the interim, it was 

 not until the Geological Survey broke ground in the Edinburgh neigh- 

 bourhood that any further detailed work of this nature was under- 



* The study of the Fishes has been resumed by Dr. Traquair, F.G-.S.
