§ 6. GEOLOGICAL AND GEOGRAPHICAL. 



The geological relations of the limestones and other foraminifera-bearing rocks of the 

 Carboniferous period form a subject altogether too wide and multiform to admit of 

 treatment in any space that could be here devoted to it ; but, inasmuch as the value of the 

 information furnished under the head " Distribution " depends upon the care which has 

 been exercised to obtain accurate knowledge of the locality and geological source of every 

 batch of material examined, it seems essential that the palaeontological portion of the 

 memoir should be preceded by particulars sufficiently detailed to answer the requirements 

 of the geologist and to ensure the ready identification of each habitat. I am especially 

 indebted to my friend Mr. Geo. A. Lebour, P.G.S., for help in this matter. His wide and
