 logical Survey's Special Reports on the Mineral Resources of Great 

 Britain, dealing with Barvtes & Witherite (vol. ii) and Fluorspar

Numerous works have been also received from the various 

 Colonial Geological Surveys ; and those of the States of Australia 

 have presented several of economic importance. 



The number of Maps received shows an increase ; there has 

 been presented during the year 36 sheets from the Geological 

 Survey of Queensland, 12 sheets accompanying Dr. A. Wade's 

 report on Petroleum in Papua, 4 sheets from the Geological Survey 

 of Sweden, 4 sheets from that of the Union of South Africa, 

 2 sheets from that of Scotland, and one each from the Geological 

 Surveys of England and Ireland. Mention should be made also 

 of the acquisition of William Smith's map of the Hackness Hills 

 (1832), and of the manuscript map of the Federated Malay States 

 prepared by Mr. J. B. Scrivenor from all sources, and representing 

 all that was known of the geologv of that region up to the end 

 of 1916. 



Mr. Thomas Sheppard has been engaged in cataloguing the Maps 

 of the British Isles. The catalogue of the Society's collection of 

 separately-published maps is practically completed, and contains 

 about 300 items. It includes an unrivalled series belonging to 

 Grreenough and a large number of valuable manuscript maps, which 

 are described in detail. In addition to these loose maps, all those 

 •contained in serial publications will be dealt with, and for this 

 purpose the publications of the various British Geological Societies 

 and Associations, as well as most of the local scientific societies 1 

 Transactions, and the various Geological Survey Memoirs have 

 been examined and catalogued. Mr. Sheppard does not propose to 

 include maps published by the Geological Survey. The bulk of 

 the catalogue • is now in manuscript, and the number of entries 

 already exceeds 3000, but there still remains a great number of 

 pamphlets and miscellaneous publications which must be examined 

 before the catalogue can be regarded as really representative of all 

 the geological maps of the British Isles. Much of this work has 

 to be done away from London ; but Mr. Sheppard hopes to devote
