Extract

As Professor Blake, in his elaborate paper in the Quarterly Journal of the Geological Society for August last, makes frequent reference to my work in Anglesey, I may perhaps be permitted a brief comment. I do not intend to enter upon an elaborate controversy, since I prefer, now that the two views of the district have been published, that those interested in the matter should visit the ground, and judge for themselves. Nevertheless, it is well that the salient points of agreement and difference between the two readings should be placed in a clear light.

References

page 562 note 1 In a note to p. 483, Prof. Blake has “little doubt” that I sent to Prof. Bonney fragments included in the Palæozoic in mistake for specimens of the rock in situ! I make no comment on this suggestion, as I am unwilling to believe it was seriously intended.

page 562 note 2 Several specimens were described in my paper (Nos. 124, 125, 126).

page 563 note 1 The italics are mine.

page 563 note 2 Prof. Blake calls this an “agglomerate.” As the contained fragments, which are rounded, are mainly quartzite, with grits and hornstone in smaller proportion, I do not see the applicability of the term.

page 563 note 3 I used this name for the Longmynd series in a paper contributed to the Transactions of the Shropshire Archaeological Society in 1887, on the ground that its Cambrian age was doubtful.
