The older Palaeozoics were discussed by Prof. W. S. Reynolds 

 and Mr. Fearnsides in two very su^g'estive papers. 



Palaiontolog-y, usually not very prominent in B.A. meetings, 

 was very much to the fore. Mr. Seward and Mr. Danford 

 respectively described the Jurassic Flora of Yorkshire and the 

 Speeton Ammonites. Dr. H. Woodward exhibited and des- 

 cribed a wonderful series of Arthropods from the Coal Measures, 

 found by an enthusiastic band of workers in the neijjhbourhood 

 of Rochdale. 



Dr. A. S. Woodward reported on the structure and affinities 

 of Rhynchosaunis after a careful examination of all the available 

 specimens ; and Mr. H. C. Beaseley followed up the careful 

 work he has done in connection with Triassic footprints, by a 

 description of the g-reat finds which have recently been made in 

 Storeton in Cheshire. 



Among- the Petrographical and Mineralogical papers great 

 interest was shown in a remarkable specimen of Sodalite from 

 India. It has a bright carmine colour when freshly broken, but 

 changes to grey or white almost immediately on exposure to 

 lig-ht. The most remarkable feature of this mineral is that the 

 carmine colour is restored on keeping; it in the dark for some 

 time. Mr. Holland, who exhibited the specimens, could suggest 

 no explanation of this phenomenon, which so far as is known 

 is unique. 



Prof. Edg-eworth David announced the discovery of diamonds 

 in their original matrix. It is strang-e that only two or three 

 undoubted examples have been found, and we are still in some 

 doubt as to the exact conditions under which the gem has been 

 formed in the natural state. 



Prof. Milne gave a most interesting account of the recent 

 world-shaking Earthquakes, and it really seems at last as 

 though some means would shortly be forthcoming whereby we 

 shall be able to predict the occurrence of earthquakes and 

 assign them to some common cause. 



The papers presented to Section C were so numerous that it 

 was impossible to deal with them adequately, and several of our 

 prominent members were lent to other sections where geological 

 subjects were under discussion. Thus in Section A the condition 

 of the earth's interior was under consideration. Section E 

 borrowed Mr. Clement Reid, Mr. Whitaker, Prof. Kendall, and 

 others to speak on Coast Erosion. Fossil plants have for 

 some years past formed one of the most exciting topics for 

 discussion in Section K.
