i. STRICKLAND. FITTON. 7 



Geological Society, in 1836, a large and valuable series of sections 

 of strata and lists of fossils from the beds below the chalk. In 

 this excellent memoir we find several careful measures of strata on 

 the line from the chalk hills through Hazeley, Garsington, and 

 Shotover to Oxford, and on the line from Stokenchurch through 

 Tetsworth to Wheatley. His notice of Shotover Hill is derived 

 from a communication by Mr. H. E. Strickland. Dr. Fitton also 

 published a notice of the Strata of Stonesfield, which had yielded 

 the jaws of Amphitheria and Phascolotheria n . 



Finally, short memoirs accompanying the sheets of the Ordnance 

 Survey, make us acquainted with the observations recorded during 

 their examination of the region round Oxford by Professor Ramsay, 

 Mr. Etheridge, Mr. Avelyn, Mr. Hull, Mr. Green, Mr. Whitaker, 

 and Mr. Polwhele. 



After the publication of the Map of the Strata of England and 

 Wales by Mr. Smith, appeared from the same hand many County 

 Maps, including Oxon, Berks, Bucks, and Gloucester. Dr. Buck- 

 land gave in his Reliquiae Diluvianse, pi. 27, a broadly-sketched 

 Map of the geological structure of the drainage of the upper Thames. 

 (1821). Dr. FitWs Map (1836) of the South-East of England 

 shows the country on the south of Oxford. An excellent Map on 

 a large scale of the district immediately surrounding Oxford was 

 published by Mr. Stacpoole of New College ; and a few years since 

 the Geological Survey of Great Britain completed the sheets of a 

 larger tract round the city. 



Some years since Mr. Whiteaves explored the oolites near Oxford 

 with great success, and discovered many fossils not previously found 

 in them. The catalogues which he composed will be referred to 

 hereafter. 



My own contributions to the illustration of the Geology of the 

 country which surrounds my lecture-room may be briefly noticed. 



The volume of ' Essays/ written by Members of the University, 

 and published in 1 855, contains, among other literary and scientific 

 memoirs, a notice of the Geology of the country round Oxford, the 

 germ of the present work. During the sixteen years of my Pro- 

 fessorate, I have been constantly attentive to the points then 

 proposed for consideration. Within this period our Collections
