Edward Wethered. Yorkshire. 

 On the Structure and Origin of Carboniferous Coal Seams. [Review of literature 

 on this subject. Section of Better Bed at Low Moor given, and results of micro- 

 scopic examination inch by inch through the seam carefully detailed. The 

 author is unable to endorse Prof. Huxley's statements as to the structure of 

 coal, as though the first 3 in. from the top is very largely nlade up of 

 macrospores and microspores, and the same may be said of the layer 4 in. 

 from the top, though they are mostly of a different species to those above, 

 yet below that point spores form but a small proportion of the whole mineral.]

W. C. Williamson. Lancashire, Yorkshire. 



On some undescribed tracks of Invertebrate Animals for the Carboniferous 

 Rocks, and on some inorganic phenomena, simulating plant remains, produced 

 on tidal shores. [Brief abstract given, mentioning a new form of Chrossocorda, 

 which the author regards as merely tracks of marine animals, in opposition to 

 the views of Schimper and others, who think this genus represents some 

 fucoidal form of Palaeozoic life. A second form of track found by J. W. 

 Davis, F.G.S., at Hawes, in the Yoredale beds, has been named Protichnites 

 davisi after its discoverer. Casts of markings produced recently by drainage 

 lines combined with ripple marks left by the retiring tide, producing an effect 

 easily mistaken for the geometrically arranged scale leaves of some Cycad, 

 were exhibited at the reading of this memoir]. Proc. Manch. Lit. and Phil. 

 Soc, 1885, xxiv, 37-38. 



E. Wilson. Lincolnshire.

 discovery as a valuable article of mining industry. Refers to Lincolnshire. ]
