For engiarings and descriptions of the MoUusca of the Great Oolite, see Palseontographical 

 Society's Publications, vols, for the years 1850, 1853, 1855 1861, by Messrs. Lycett & Morris ; also 

 contributions by Mr. Witchell and others, to Proceedings of the Coteswold Club. 



+ An elaborate and very valuable contribution to the Geology of Wiltshire, is contained in a paper 

 by Professor James Bdckman, F.G.S., F.L.S., F.S.A., " On the Oolitic Koelis of Gloucestershire and 

 North Wilts," read before the Geological Societt, June 17th, 1857, and printed in the Journal of 

 that Society, vol. xiv., p. 98. It is illustrated by a very accurate section of the country from Bu-dlip 

 to Swindon, and from Blunsdon to Wanborough Hill, by Professor Armsteomg, C.E., besides other 

 sections, tables of analysis, and lists of fossils. 



Thus the northern portion of the county has been well explored by some of the best geologists. 

 Of the middle and southern districts, though surveyed by the Ordnance officers, little has been 

 published.
