110 REPORTS ON THE STATE OF SCIENCE. 



VI. Vise. 



The whole of the Carboniferous limestone of Vise belongs 

 to the Upper Dibunophyllam zone, for the lowest beds (said to 

 rest unconformably on the Devonian) contain Dibunophylla and 

 Densiphylla of Upper D habit. 



The higher limestones contain species of Dibunophylla, 

 Cyclophylla, &c, which ally them to the coral beds of Derby and 

 North Wales. In accord with this is the fact that the Brachio- 

 pods are identical with those of the Brachiopod beds of 

 Wetton, &c. 



Vise is the only locality in Belgium at which a characteristic 

 D coral fauna has been discovered. In N. France, near 

 Avesnes, the uppermost limestones with Prod, latissimus contain 

 an identical coral fauna indicating D 2 -Dy. 



Investigation of the Igneous and Associated Rocks of the Glensaul 

 and Lough Nafooey Areas, Cos. Mayo and Galway. — Report of 

 the Committee, consisting of Professor W. W. Watts (Chairman), 

 Professor S. H. Reynolds (Secretary), Mr. H. B. Maufe, and 

 Mr. C. I. Gardiner. 



Mr. C. I. Gardiner and the Secretary completed their field-work on 

 the Glensaul area in April 1909, and their paper was published in 

 the ' Q. Journ. Geol. Soc.,' vol. lxvi. (1910), pp. 253-279. At the 

 same time they commenced work on the rocks of the Kilbride peninsula 

 (Lough Nafooey area), and have devoted three weeks in July and August 

 1910 to a continuation of the work, which is not yet completed. The 

 general structure, however, of the Kilbride Peninsula may be briefly 

 described as follows. The southern and eastern part consists in the 

 main of Silurian grits and flags, dipping with great regularity in a 

 general south-easterly direction, and including a highly fossiliferous 

 Upper Llandovery horizon. The northern and western portion con- 

 sists principally of igneous rocks — quartz felsite, vesicular andesitic 

 rocks, labradorite porphyrite, and coarse breccia. As yet the only 

 fossils found in this part of the area are a few Didymograpti and a 

 crustacean, probably a species of Caryocaris. In Die south-eastern 

 corner of the peninsula is an area of gneissic rocks against which the 

 Silurians are faulted. 



Composition and Origin of the Crystalline Rocks of Anglesey. — Fifth 

 Report of the Committee, consisting of Mr. A. Harker (Chairman), 

 Mr. E. Greenly (Secretary), Dr. J. Horne, Dr. C. A. Matley, 

 and Professor K. J. P. Orton. 



The end of the present geological work upon Anglesey is now within 

 sight. The map will, all being well, be completed during the coming 

 autumn, after which the descriptive memoir will be the only undertaking
