Extract

My interest in cleat was first aroused by the study of the Geological Survey memoir on the coals of South Wales (1908), from which it became clear to me that the subject of the origin of anthracite was intimately bound up with that of cleat. The object of the present communication is, however, not directly connected with the anthracite question, upon which I hope to have something to say when researches upon which I am engaged with Mr. E. J. Edwards, M.Sc., of Cardiff, have reached a more advanced stage.

page 49 note 1 Since this was written I have learned that in the South Wales Coal-field cleat is known as ‘slips’: with this clue I found an allusion to ‘slip-cleavage’ in the memoir above mentioned. It stated that there was none in anthracite.
