CONCLUSIONS. 



Reviewing the results of the palseontological evidence, we 

 ' see that the age of the Black Limestone cannot be inferred 

 from the fossils it contains ; however, the presence of the 

 genus Marginifera is in favour of a correlation with the 

 Upper Carboniferous, or with the Artinskian stage of Russia. 

 The occurrence of a Fusulina, apparently identical with the 

 form found in Bear Island and Spitsbergen, in beds which 

 Mr Anderson corraeltes, in the Appendix to his paper, with 

 the lower part of the Upper Carboniferous formation of 

 Russia,^ points to the probable presence of beds of that age 

 in Prince Charles Foreland (assuming that the fragment of 

 ' rock collected by Dr Bruce is not a glacially transported 

 one). 



Productus horridus proves the presence of Permian strata 

 in the island, and it is also interesting to note the occurrence 

 of Bryozoa reefs similar to those which are met with in the 

 Zechstein of Germany and the corresponding strata of York- 

 shire. It is to be hoped that more material may be obtained, 

 and that the study of a more complete assemblage of fossils 

 from these beds will show their exact position within the 

 Permian system, and their homotaxial equivalents in Spits- 

 bergen and elsewhere. 



Tertiary beds, with dicotyledonous plant remains, having 

 been found, in situ by Dr Bruce, it is permissible to infer 

 that Mesozoic strata underlie them as in Spitsbergen, and 

 that such may be discovered in the course of future expedi- 

 tions to Prince Charles Foreland. 



^ In his second paper Mr Anderson places these beds in the uj^per portion 

 , of the Middle Carboniferous {Joe. cit., 1901, p. 222).
