58 PROCEEDINGS OP THE GEOLOGICAL SOCIETY. [May 1 894, 



ON SOME RECENT WORK OE THE GEOLOGICAL SOCIETY. 



Part II. 



In" continuation of the subject of the preceding Anniversary- 

 Address it becomes my duty, on the present occasion, to attempt 

 some notice of a portion, at least, of the numerous papers con- 

 tributed within the septennial limits, which were left untouched 

 last year. These I would roughly divide into two groups. 



In the first group are placed papers relating to the Newer Palaeozoic 

 Rocks, the Older Palaeozoic Rocks, and the Fundamental Rocks, 

 which bear upon the geology of the British Isles or their immediate 

 vicinity. With these will be associated a large series of papers on 

 General Petrology, dealing chiefly with igneous and metamorphic 

 rocks, though I shall not attempt to touch upon matters which are, 

 in the main, petrographical. 



In the second group are numerous papers which may be roughly clas- 

 sified under the following headings : Miscellaneous Geology, Foreign 

 and Colonial; Miscellaneous Invertebrate Palaeontology ; Paleobotany; 

 and lastly Dynamical Problems. This group of subjects is so varied 

 and so large that it would be impossible, within the limits of an 

 address, to deal with it in anything like a comprehensive manner. 

 Nevertheless, many of the papers are of great value ; as, for instance, 

 ' The Contribution to the Geology and Physical Geography of the 

 Cape Colony,' by Prof. Green ; ' The Geology of the Wengen and 

 St. Cassian Strata,' by Miss Ogilvie ; ' The Leaf-beds and Gravels 

 of Ardtun in Mull,' by Mr. Starkie Gardner ; not to mention others 

 of equal interest. Before proceeding, therefore, to a more detailed 

 consideration of the first group of papers, I submit a kind of synopsis 

 of the second group under the headings above indicated. 



Miscellaneous Geology, Foreign and Colonial. — This is of course a 

 somewhat exhaustive division, comprising about a score of papers, 

 which deal with many subjects in different parts of the world. 

 Thus, we have had several communications respecting Africa. Indeed 

 it is scarcely too much to say '.that the outlines of the geology of the 

 ' Dark Continent ' are by degrees being made known ; and we may 

 hope that, when Mr. Gregory has time to tell us the story of Mount 

 Kenia, the Geological Society will be in possession of further details 

 respecting a region which is now attracting so much attention. 

 I have already alluded to Prof. Green's paper, where he gives a
