14. Some J^EW Caebonifeeotis Plants, and how they contributed to 

 the Poemation of Coal- Seams. By W. S. Geeslet, Esq., 

 P.G.S. (Eead February 23rd, 1898.) 



[Abstract.] 



The Author, in a paper published in abstract in the Society's 

 Quarterly Journal for May 1897 (vol. liii, p. 245), argued that certain 

 brilliant black laminae in coal, aud similar materials found among 

 some mechanical sediments of the Coal Measures, pointed to the 

 former existence of an aquatic plant. In the present communication 

 he describes structures in the pitch-coal laminae of bituminous coal 

 and in the glossy black layers of anthracite which he believes to 

 be indications of two other kinds of plants, and states that he 

 has examined structures which may be due to some other kinds of 

 vegetation. 



Discussion". 



Mr. Steahan admired the persistence with which the Author 

 brought forward his views on these so-called coal-plants, and 

 regretted that there was not better evidence of the origin ascribed 

 to them. 



Dr. Hicxs and Dr. Hixde also spoke. 



15. CoNE-iN-CoNE : Additional Facts from Yaeious Cofnteies. 

 By W. S. Geeslet, Esq., F.G.S. (Eead March 23rd, 1898.) 



[Abstract.] 



Examples of flinty stone in the ' fire-clay series ' of the Ashby 

 coal-field exhibit ' areas of conic structure lying unconformably.' 

 In the same stratum of shale are large masses of the same flinty 

 rock, more or less coated with conic structures, which appear to 

 ha.ve been formed out of layers of shale and ironstone. The 

 bending-up of the shale above the nodules and down below them, 

 the close but unconformable covering of Permian breccia, and the 

 staining of the whole section suggests, if indeed it does not 

 demonstrate, to the Author that the growth of the cone-in-cone 

 took place subsequently to the deposit of the Permian breccia. 

 Several American and other examples are described, and a series of 

 conclusions are appended to the paper. 



Discussion. 

 Mr. Clement Keid and Mr. Steahan spoke.
