26S EEPORTS OX THE STATE OF SCIENCE. 



;iiid it ia iiupfed that further information will bu forthcoming as a resul t 

 of the visit of the British Association to Dublin. 



Owing to the large demands made by the Irish work upon my leisure, 

 the publication of an account of the Avonian Sequence in the Gower 

 peninsula, which was carried out in collaboration with Mr. E. E. L. Dixon 

 in the summer of 1905, is again deferred. 



II. — Examination of Material siibmitted for Identification hy other 

 Workers on Lov)er C arhoniferoiis Rocks. 



The wide application of the zonal sequence determined for the 

 South-Western Province is strikingly exhibited, and the satisfactory 

 correlation of phasal developments is already in view. 



Til. — Mr. Edward Greenly has collected a fine series of fossils from 

 the Lower Carboniferous Rocks of Anglesey, and has kindly allowed me 

 to draw up an account of the faunal succession from his material. 

 This account will be published shortly in connection with Mr. Greenly's 

 description of the Rock Sequence. 



The points of main interest are : — 



(a) Zonal. — The possibility of subdividing Do by mutational species 

 of Lonsdalia and Diphyphylluin. 



(h) Stratigraphical, — The age of the basal Carboniferous in Anglesey. 



IV". — Paleontology. 



(1) Notes published in Dr. Matley's Loughshinny paper. 



(2) Investigations of the inter-relation of the genera 



(a) Sjiiriferina and Syringothyris. 



(b) Orthotetes and Derbya. 



The results will be published as occasion offei'S. 



(3) Study of the Corals included under Caninia cylindrica in my 

 Bristol paper, and of some allied forms recently discovered. 



This work is being carried out in collaboration with Mr. R. (i. 

 Carruthers, and will be included in his general revision of the Carboni- 

 ferous Corals. 



The grant for this year has been expended on the cutting and 

 photographing of Coral Slices. 



For determination of horizon from Corals the satisfactory comparison 

 of new material with the zonal types already accumulated demands — 



(1) The cutting of transverse slices from the adult corallum. 



(2) The photographing of the slices on an enlarged scale. 



(3) The comparison of these photographs with those of the types. 



Bv this method the misleadins; effects of difference of matrix are almost 

 completely eliminated. 



In view of the important in\estigations now being carried out 

 in widely distant areas by numerous workers in Avonian Rocks, and in 

 the probability that my services may be of use in identification or con- 

 firmation, I venture to suggest the continuance of this Committee for yet 

 another year, with a further grant of 1 0/.
