AS these two memoirs are descriptive of adjacent areas and both 

 are second editions, we may conveniently associate our remarks 

 upon them. 



The first edition of the Geology of Edinburgh was written by 

 H. H. Howell & A. Geikie, and published in 1861 ; and that on East 

 Lothian, the work of Howell, A. Geikie, & J. Young, was published 

 in 1866. A long interval has thus elapsed, and both memoirs required 

 much revision and very considerable additions. More than 030 papers 

 on the local geology are recorded in the Edinburgh bibliography as 

 published since 1861 ; and in the list we find the names of numerous 

 local workers who have contributed papers, and of tbese J. Henderson 

 and D. J. Brown are more especially mentioned in the text. The new 

 work is, however, essentially based on observations made during the 

 re-survey or revision of the areas on the Geological Survey maps. 



The Edinburgh Memoir, which has been edited by Dr. Horne, 

 describes the geological features of the district included in the 1 inch 

 map 32 — the first published sheet of the Geological Survey in 

 Scotland — together with a narrow belt of ground extending from 

 Addiewell by Bathgate to Bo'ness in Sheet 31. 



In the introduction is given a brief sketch of the prominent physical 

 features and the geological history of the region. The records of the 

 older Pala3ozoic rocks, comprising the Silurian formations and the 

 lower and upper divisions of the Old Bed Sandstone, are described, 

 a special chapter being devoted to the Petrography of the Volcanic 

 Bocks of the Pentland Hills, of which a good pictorial view is given 

 in a plate. 



The distinctive feature of the memoir is the detailed description of 

 the various divisions of the Carboniferous System occurring within the 

 region, including the Oil- shale fields of the Lothians, the Carboniferous 

 Limestone Series and associated coals of Bo'ness and Bathgate, and the 

 Mid-Lothian basin with the Edge Coals and true Coal-measures. 



The Millstone Grit or Boslin Sandstone Series was rightly mapped 

 in the original survey as one essentially arenaceous and pebbly
