244 REPORTS ON THE STATE OF SCIENCE. 



Ueijorted hy Mr. J. W. Statiier, F.G.S. 



At Aldboi'ouoh in Hoklerness (observed by Mr. Charles Thompson, 

 B.Sc.) a mass of Speeton clay, 12 feet x7 feet x 1 foot 6 inches, embedded 

 in the bonlder clay of the beach. The bedding is still intact, and the 

 contained fossils uncrushed. 



The full extent of the boulder could not be seen, as it dipped towards 

 the cliff. 



The following fossils were noted ;— 



Exogyra sinuala. 



Belemnitcs siibquadrafiis, 



Asiarie senecta. 



Also numerous ammonites, all belonging to the zone D^,^ 



The only other recorded case of a transported mass of Speeton clay 

 is at Flamborough Head, immediately below tho lighthouse, though 

 Speeton fossils are very common in the drifts of this coast. 



The distance from Speeton to Aldborough is between 20 and 23 

 miles. 



liP.porled by Mr. H. Colpix. 



From a cutting on the South Yorkshire Joint Railway at Stainton 

 Woodhouse, two miles M'est of Tickhill. 



Carboniferous limestone, 6 inches x 5 inches x -1 inches, together with 

 smaller pebbles of the same rock and of grit. 



Also a boulder of a dark grey rhyolite with large masses of iron 

 pyrites, probably from the Borrowdale Series. 



Reported by Mr. J. Wilfrid Jackson. 



A large boulder of Shap granite from Troughbarrow Quarry, near 

 Silverdale, Lancashire. 



ReporUd hy Mr. F. W. Harjier, F.G.S. 



A number of small chips collected by Mr. Harmer from boulders 

 found in the Norwich briclc-eaith were forwarded by Mr. Hai-mer. Of 

 these thin sections have been prepared, and have been examined petro- 

 logically by the Secretary. 



They include a number of holocrystalline acid rocks, including both 

 biotite and muscovite-biotite granites, which it has been impossible to 

 identify up to the present. 



Dolei-ites are represented by two types : one of these (five specimens) 

 is without olivine, and has been identified with the Whin Sill. TtiQ 

 other type is olivine- bearing, and has not as yet been identified. 



The collection also included Carboniferous limestone, with fora- 

 minifera and other small fossils, two pebbles of porphyrite of the 

 Cheviot type, and a quartz hornblende schist, probably Scandinavian. 



From the Cromer Clay.— Here, again, was found a number of granites 

 not as yet identified. 



Whin Sill was represented by eight specimens. 



Olivine dolerites, similar to those from the Norwich brick-earth, also 

 occurred here. 



A porphyrite of Cheviot type was also found. 



Several quartz-hornblende-schists, bearing a strong resemblance to,
