sicnlar appendage) never takes place except much outside the 

 surrounding stipes, it is almost impossible to make the mistake of 

 considering the appendage as part of a third branch." Tins 

 statement was singularly misinterpreted by Dr. Holm in his paper 

 "On Dirfymograptits, etc." But, as I thought I had expressed 

 myself pretty clearly, and did not fear that any other Swedish 

 reader might misunderstand the meaning, after having privately 

 pointed out his error to Dr. Holm, I did not think it called for 

 any public reply. I was therefore not a little astonished at 

 finding that in the English version my statement was still further 

 misrepresented. The English reader must be convinced that \ny 

 assertions on two consecutive pages are contradictory. But my 

 statement in the before-mentioned footnote is, as everyone can see, 

 in full accordance with the views presented on the preceding pages, 

 and totally contrary to the version given by Dr. Holm. 



Hoping shortly to find time for working out a description of an 

 interesting Graptolite-type, which I have met with, I will for the 

 present refrain from making any further remarks about the genus 

 Isograptus, which, I believe, should still be maintained.

Further Notes on Eozoon Canadense by Sir. "Wm. Datyson, C.M.G. 



Note to Second Article. — I should have mentioned in this 

 article that Dr. F. D. Adams has shown, by comparison of a number 

 of detailed analyses, that several of the gneisses of the Grenville 

 Series have the chemical composition of Palaeozoic slates, and thus 

 that there can be no chemical objection to regarding them as altered 

 sediments. This I consider a very important observation ; and 

 I may refer for details to his paper in the American Journal of 

 Science, July 1895, vol. l, p. 58. 



Note to Third Article. — The tubes penetrating some of the 

 larger specimens of Eozoon may perhaps be compared with the 

 central canal in the modern Carpenteria. — W.D. 



■Sections of Bunter and Keuper, etc. 

 During the construction of the Seacombe branch of the Wirral 

 Railway the strata have been examined by Mr. T. W. Davies and 

 Mr. T. Mellard Reade. Sections of Bunter, Keuper, and Glacial 

 Drift are described by them. They note evidences of denudation 

 of the Bunter prior to the accumulation of the Keuper. The Glacial 

 Drift was found to comprise two beds of Boulder-clay separated in 

 places by sand. In the Lower Clay abundant Foraminifera were 

 discovered, while but few occurred in the Upper Clay. (Proc. 

 Liverpool Geol. Soc, vol. vii, part 3.) 



Mr. R. Bullen Newton is continuing his useful work on the 

 Eocene Mollusca, and has described a number of Gasteropods which 

 have hitherto received only MS. names. (Proc. Malacological Soc, 

 vol. i, part 7.)
