104 KEPORTS ON THE STATE OF SCIENCE. 



Reported by the Hull Geological Society. 



Mr. C. Thompson, B.Sc, reports that he has obtained from the 

 boulder clays of Holderness, chiefly from the neighbourhood of Ald- 

 brough, ammonites representing all the zones of the Yorkshire Lias. 

 In addition recent work has yielded at least twenty species new to York- 

 shire records, or only doubtfully inserted therein. 



Mr. S. S. Buckman has named nineteen of these specimens, and 

 they include at least four species new to science. 



The excavations for the new dock at Marfleet, near Hull, have dis- 

 closed some fine sections in the Humber warps, forest beds, and under- 

 lying glacial clays. From the latter, two boulders of shap granite have 

 been obtained, the larger of which measures 16 x 14 x 12 inches. 



Mr. Stather reports that, as a result of the work done by Dr. V. 

 Milthers on the Scandinavian boulders found in Denmark, and the 

 examination of type rocks with which Dr. Milthers supplied him, he 

 has been able to recognise several types not previously recorded from 

 the Yorkshire boulder clays. 



Dr. Milthers recognises many Scandinavian erratics in Denmark, 

 and divides them into five classes: — 



(1) Those from Christiania district. 



(2) Those from Dalarne district. 



(3) Those from Scania. 



(4) Those from Eastern Smaland.__ 



(5) Those from the North Baltic, Aland, &c. 



It is, of course, well known that rocks from the Christiania district 

 are of common occurrence in the drifts of our East Coast, and with 

 Mr. Milthers' specimens for reference three new records have already 

 been made, and it is hoped that it will be found possible to identify 

 many of the other rocks. 



The new records are — 



(1) Bredvad porphyry from Dalarne. 



(2) Gronklitt porphyrite from Dalarne. 



(3) Red Sarna porphyry from Dalarne. 



Mr. Stather expresses the opinion that the Dalarne rocks will be 

 found to be quite as common in the glacial beds of the East Coast as 

 are those from the Christiania district. 



IRELAND. 



Reported by the Committee of the Geological Section of the Belfast 



Naturalists' Field Club. 



The Committee record the extension of Ailsa Craig Riebeckite-eurite 

 to Coleraine (see below). 



Co. Armagh. 



Armagh (catling through boulder clay, Light Railway, near 

 Armagh). — 230 boulders noted; 64 per cent, were erratics, and included
