In the GeologicalMagazine for 1870 (Vol. VII., p. 267), I published a brief account of some burrows in Derbyshire; one group of. which, at the bottom of Miller's Dale, and on a scarp of rock which was probably artificial, appeared to me wholly irreconcilable with the theory which attributes them to the action of Pholades.
Read before the Cambridge Philosophical Society, April 29, 1872.

page 317 note 1 For example, during a brief visit to Cheddar last July, I did not come upon quite the right kind of rock, and only found two or three burrows—and these in a boulder—that satisfied me. It will not, however, surprise me if they are found there; for I had other matters in hand, and was too hurried to look carefully for them. Mr. Main, Lecturer in Chemistry at St. John's College, Cambridge, has kindly analyzed for me a fragment of the limestone from Derbyshire. He finds only 3·5 per cent of foreign matter, the rest, 96·5, being carbonate of lime.
