contributed by Professor W. Boyd Dawkins, are now for the first time 

 published. These borings, however, did not extend to the Palseozoic 

 floor. We should have been glad to see details also of the Secondary 

 strata passed through at the Elliuge, Ropersole, Waldershare, and 

 Fredville borings, which reached Coal-measures, and of the Brabourne 

 boring, which reached Devonian or possibly Silurian (as suggested on 

 p. 383). Becords of the Dover pits are given, summarized to some 

 extent from accounts previously printed. 



Many analyses of water have been contributed by Dr. Parsons, on 

 behalf of the Local Government Board, and by Dr. Thresh, while the 

 statistics of rainfall have been prepared by Dr. Mill. tV Bibliography 

 together with Miscellanea and Addenda form the concluding portions 

 of this volume. 



In the memoir on the "Water Supply of Bedfordshire and North- 

 amptonshire the Geological Survey has had the advantage of the 

 services of Mr. Beeby Thompson, whose researches on the geology of 

 Northamptonshire, from a practical as well as scientific point of view, 

 are well known. He has contributed, in addition to numerous records 

 of well-borings, a full account of the springs around Northampton, and 

 of the various schemes for supplying the town with water from the 

 date of the earliest record, which was in the thirteenth century. 

 He has also written notes on the characters of the Northamptonshire 

 waters, and supplied records of original analyses. The particulars 

 relating to Bedfordshire have been arranged and classified by Mr. H. B. 

 Woodward, who has written the general outline of the geology of the 

 two counties, with notes by Mr. Thompson and Mr. Jukes-Browne. 

 Various records of wells and borings have been contributed by 

 Mr. Whitaker and Mr. A. C. G. Cameron, and the sections on rainfall 

 have been drawn up by Dr. H. 11. Mill. We note on p. 64 that the 

 grouping "Alluvial Drift" is printed in mistake for Glacial Drift. 

 The volume concludes with a Bibliography. 



V. — The Geological Society of London. 



rpHE record of "The Centenary of the Geological Society of 

 J[. London ", prepared by Professor W. W. Watts, late senior 

 Secretary of the Society, has been issued uniform with the Quarterly 

 Journal (pp. vi, 166) at the price of 2s., and with an excellent 

 portrait of Sir Archibald Geikie. The main features are the report 

 of the reception of the delegates, the addresses of congratulation 

 from individuals and institutions representing all parts of the world, 

 and the presidential address delivered by Sir A. Geikie. 



Most of the addresses are in English, but others are in Latin, 

 French, German, and Dutch. Many of them were elaborate in 

 design, of great beauty and artistic merit. 



The oldest institution that tendered congratulations was the Koyal 

 College of Physicians, now in the 389th year of its corporate 

 existence. It was represented by Dr. Michael C. Grabham, who 

 also issued an independent address to the President and Fellows 

 entitled "The First Hundred Years of the Geological Society of 

 London". In this essay the author remarks "we may sui-ely ask
