part 1] PEOCEEDINGS OF THE UEOLOGHCAL SOCIETY. ci 



England and Wales was a small one, also by Smith, and it was 

 presented to the Societj^ by 'the Father of English Geology' when 

 the first Wolki-ton Medal was awarded to him in 1831. The 

 Lecturer discussed the histor}^ of the various maps and sections pub- 

 lished by Smith, and described two hitherto miknown maps (of the 

 counties of Durham and Northumberland) by the same author, in 

 the Society's possession. He also exhibited one of the Scarborough 

 district, found while he was cataloguing the Society's maps ; all 

 trace of this particular map had been lost for over eighty years. 

 Smith's finest piece of work, his map of the Hackness district, dated 

 1S82, apparently had not been seen by any worker since its publi- 

 cation, and the Lecturer explained how he had recently been able to 

 trace two copies. One of them, which was exhibited, he presented 

 to the Society. 



In the Society's possession also is an extensive and valuable 

 collection of the maps of Grreenough, both published and in 

 manuscript. Among an extraordinary series of coloured maps of 

 England and Wales, and of the British Isles, issued during the 

 middle of the 19th centmy, those of Arrowsmith, Murchison, 

 Walker, Ramsay, Ravenstein, Knipe, Phillips, and Johnston are 

 especially notewoi'th}^ 



The Society's collection includes geological maps of Scotland and 

 Ireland, some of great value and historical interest. Of Scotland, 

 the remarkable series b}'^ MacCulloch, published and in manuscript, 

 shows that the collection is b}" far the finest as regards early maps 

 dealing with the geology of the country. A manuscript map of 

 Scotland by Necker is dated 1808 (earlier than Smith's large map 

 of England and Wales), and is undoubtedly the oldest. Among 

 the maps of Ireland there is the fine series by Oriffith, which 

 includes a few examples not known by Judd or other writers on 

 the subject. 



As examples of privately published maps, those by Sanders of 

 the Bristol Coalfield, Jordan's London District, and Elias Hall's 

 Lancashire area were described. The Lecturer concluded by 

 referring to a Catalogue of geological maps (other than the Geolo- 

 gical Survey Publications) which he had in course of preparation. 

 This already contained details of approximately 3000 maps. 



The President commented on the value of Mr. Sheppard's work, 

 and on the important discoveries that he had made, and expressed 

 the thanks of the Fellows present for his lecture. 



Lantern-slides and examples of important early geological maps 

 were exhibited in illustration of the lecture.
