ir many hands make light work the production of this memoir ought 

 to have been an easy task, especially as the above list does not 

 contain the names of all who were officially engaged in the Geological 

 Survey of the area, the original maps (published 1870-8) having been 

 the work of E. Hull, J. Geikie, B. JS^. Peach, and B. L.Jack. More- 

 over, there are contributions in the memoir from other members of the 

 Survey : notes on fire-clays by J. Allen Howe, with analyses by E. G. 

 Badley, and a bibliography by D. Tait. The colour-printed map 

 which accompanies the present memoir includes portions of the Sheets 

 22, 23, 30, and 31, the geology has been thoroughly revised, and the 

 map (price 2s.) has been specially prepared for economic and educational 

 purposes, with Glasgow as a centre. The map itself contains a 

 wonderful amount of information, the details of the basaltic rocks 

 -being enough to appal an ordinary student ; it is, however, very 

 clearly printed, and the Glacial Drift is shown by different patterns of 

 stippling. 



The Old Bed Sandstone, the oldest formation in the district, is 

 separated into Upper and Lower divisions, which are unconformable 

 and palaeontologically distinct. JSTevertheless, the evidence of these 

 features has to be sought in other areas, as no fossils have been found 

 locally, and " there is no direct evidence of the unconformity else- 

 where so strikingly developed". The view is favoured that the Old 

 Bed Sandstone was formed under continental conditions with desert, 

 lacustrine, and river action ; while the cornstones of the Upper 

 division are likened by Mr. H. B. Maufe to the ' kankar ', which in 

 India and Central Africa has been formed in areas subject to wet and 

 dry seasons. 



'To the Carboniferous rocks Glasgow owes much of its wealth and 

 importance, and full particulars are given of the Calciferous Sandstone 

 Series, with its many basaltic lava-flows, of the Carboniferous Lime- 

 stone Series, the Millstone Grit, the Productive Coal-measures, and 

 the Upper Barren Bed Measures. Practical information is given 

 concerning the coals, the correlation of seams, the cement-stones, 

 limestones, ironstones, and fire-clays. The conditions of sedimentation 

 are dealt with both in the stratigraphical and palseontological chapters, 

 and in the latter due acknowledgment is made of the classic work of 

 the Bev. David Ure, The History of Rutherglen and East Kilbride, 

 published in 1793. In that work many of the familiar fossils, the 

 names of which appear in the lists from the Carboniferous rocks of 

 Britain and the Continent, were described for the first time. There is 

 much of interest in the chapter contributed by Dr. Lee, whose initials
