Note 132 — Chapter XII · CHARACTERS OF THE SILURIAN SYSTEM IN BRITAIN. THE ARENIG VOLCANOES
Reading edition
Mem. Geol. Surv. vol. iii. 2nd edit. p. 95, note.
[133] Some of the modifications introduced are, I think, to be regretted, for the earlier editions of the maps and sections are in certain respects more accurate than the later. On this point I concur with the criticism made by Messrs. Cole and Jennings, Quart. Journ. Geol. Soc. vol. xlv. (1889), p. 436.
