334 Correspondence — Mr. J. A. Birds — Mr. A. Strahan. 



various reasons ; because I have given up " coat strealing," and 

 principally that I cannot devote sufficient time to be such a master 

 of the Devonian sections as would give me a claim " to beard the 

 lion in its den." I must, however, say that if the Devon geologists 

 are satisfied with the evidence brought forward to refute the exist- 

 ence of Jukes's, or rather De la Becbe's fault, they are very easily 

 satisfied. 



Various Irish geologists have gone to Devon, Cornwall, and 

 Wales, to compare the Irish and the English rocks ; yet how many 

 of them have written on the English rocks? I do not know of any 

 English geologists except De la Beche (who we may nearly claim 

 as an Irish geologist) who have examined the Irish rocks, further 

 than taking a hurry scurry on a car through the country, yet we 

 are coolly asked to squash the work of years to suit these ideas. 

 Who therefore, — English or Irish, — take the cross channel view of 

 the rocks ? G. H. Kinahan.

BEEKITE IN THE CHANNEL ISLANDS. 



Sir, — Will you allow me to add to Capt. Jamieson's interesting 

 account of his discovery of Beekite in the Punjab, contained in the 

 last Number of the Geological Magazine, that this mineral also 

 occurs in a Triassic conglomerate in Bouley Bay, Jersey, described 

 in Ansted and Latham's " Channel Islands," p. 274. 



A year or two ago I picked up several specimens on the beach 

 there in pebbles containing corals and shells. Thus the range of 

 Beekite in Europe is slightly extended beyond the shores of Torbay. 



It would be interesting to know if the same conglomerate with 

 Beekite also occurs in Normandy, among the rocks believed by Mr. 

 Ussher to be a south-easterly extension of the Triassic beds of 

 Devonshire (see " On the Triassic Rooks of Normandy, etc.," by W. 

 A. E. Ussher, Esq., F.G.S., Quart. Journ. Geol. Soc, vol. xxxv. 

 p. 245). J. A. Birds.

P.S. — There is a specimen of Beekite in the British Museum, from 

 Vallecas, near Madrid. 



BEEKITE IN FLINTSHIEE. 



Sir, — Capt. Jamieson, in his letter on Beekite from the Punjab, in 

 the Geological Magazine of last month, mentions Torbay as the only 

 known locality in Great Britain for this mineral. It occurs also in 

 the Carboniferous Limestone of Flintshire, and in every specimen 

 that I have hitherto met with as a crust replacing the shell of a Pro- 

 ductus. The siliceous gangue of many of the veins and the silicifi- 

 cation of the Encrinites and other fossils in the Limestone in and 

 near such veins is a further indication of the passage of water 

 containing silica in solution. A. Strahan.
