Mr. Kirk first to remove the beara out of his own eye, and then he 

 will be able to see clearly to correct his own blunders ; and in the 

 new edition, which such a work is sure to reach, we shall hope to 

 find not only the gross mis-spellings corrected, but the insolent 

 language adopted towards so eminent a philosopher, geologist, and 

 gentleman, as Sir Charles Lyell, deleted. 



The attempt to supersede the reasonings of sound philosophy 

 founded on well-ascertained geological data, by dogmas of his own,^ 

 for which he furnishes us no proof whatever, suggests to us the 

 applicability of Mr. Kirk's own language, that "he" (not Sir Charles 

 Lyell) " is manifestly incompetent for the task he has imdertaken, 

 and that he is as eminently illogical as (no doubt) in a sense he is 

 eminently" theological (not ''geological"), "and hence he is incom- 

 petent" (see p. 114).

Vol. V. No. 14. 1866. 



1. 



SOME of the very interesting specimens of Coal -plants, found by 

 Mr. Wiinsch, of Grlasgow, in beds of volcanic ash in the lower 

 part of the Scotch Coal-measures, in the North-east part of the Isle 

 of Arran, were alluded to (on their exhibition, February 27th) by 

 Mr. Binney, as offering good proofs of the combined agency of fire 

 and water in producing stratified deposits. 2. Messrs. J. Plant and 

 E. "Williamson described the geology and fossils of the Lingula-flags, 

 or Primordial Zone, of the Gold-districts of North Wales in a paper 

 resulting from the joint researches of Messrs. Eeadwin, Salter, 

 Williamson, and Plant, on the structure of the Dolgelly country, 

 and the fossils found there.^ 



The sectional list of strata seems to be as follows : — No. 9 (upper- 

 most). Tremadoc slates, not examined. No. 8. Moel Gron slates and 

 shales, 750 feet ; equivalent to the " Black Shales of Malvern," 

 with Olenus scaraboeoides, 0. bisulcatus, 0. humilis, Sphixrophthalmus 

 pecten, Conocoryphe, Angelina Sedgwiclci, Agnostus rex, A. princeps, A. 

 trisectus, etc. No. 7, Rhyw Efely (or Rhyw-feln) slates and shales ; 

 750 feet. Orthis, Orthonota (?), Lingula, Olenus spinulosus, 0. bisul- 

 catus, 0. humilis, 0. pecten, 0. alatus, Agnostus, etc. Nos. 9, 8, and 

 7 form the Upper Lingula-flags. 



No. 6. Hafod Owen sandstones and traps ; 4,000 feet. Lingulella 

 Davisii, Olenus, Conocoryphe, Buthotrepis, Annelid-marks, etc. This 

 great group of felspathic sandstones forms the Middle Lingula-flags, 

 and is chiefly fossiliferous in its upper divisions. 



No. 5. Cwmheisian flags, traprocks, and felspathic grits ; 1500 

 feet. Olenus cataractes, Agnostus princeps, Sao hirsuta, Petraia, 

 Crustacean tracks, etc. The lowest portion is not fossiliferous.
