OF this series we have received the volumes relating to Buckingham- 

 shire by Dr. A. Morley Davies (1912), j^orthamptonshire by 

 Mr. M. W. Brown (1911), and Midlothian (Edinburgh) by Mr. Alex. 

 McCallum (1912). As would be expected, the physical features, 

 geology, and soils of Buckinghamshire are well described, and also 

 illustrated by longitudinal sections and views of quarries. The 

 geological map, as in the other volumes, does not sliow the Drift 

 deposits, but descriptions are given of Boulder-clay and gravel. The 

 economic uses of the various formations, including greywethers, are 

 noted, as well as the relations of the plants to the soils and subsoils. 

 There are good views of river scenery and an interesting map showing 

 the distribution of streams, and their absence over the higher Chalk 

 tracts ; also views of lynchets and of the old ' ridge and furrow ' method 

 of draining clay lands. 



^Northamptonshire has not such an extended series of geological 

 formations, but the map is more detailed than that of Buckingham- 

 shire. Views are given of river scenery and floods, of ironstone 

 workings at Islip and iron-works at Corby, of a stone quarry at 

 Weldon, and the splitting of Collyweston slates. Some Palaeolithic 

 and Keolithic implements are also figured. 



In the excellent account of Midlothian there is much to interest in 

 a maritime, agricultural, and industrial county. The formations 

 extend from the Ordovician and Silurian of the Moorfoot and Pentland 

 Hills to the Carboniferous of the central valley, with Glacial Drifts 

 and other superficial deposits, as well as igneous rocks. Arthur's 

 Seat is represented in a somewhat sombre view, but a better one is 

 given with the Burns Monument in the foreground. The views of the 

 romantic glens of Roslin and Hawthornden are good. Of the economic 

 products particular mention is made of the coals and oil-shales, building- 

 stones, bricks, and fire-clays. It is also noted that salt-works on 

 a small scale are still in operation for the preparation of salt rock at 

 Joppa and Pinkie Pans between Portobello and Musselburgh. 



Later volumes received, all dated 1912, are West London by 

 Mr. G. F. Bosworth, Oxfordshire by Mr. P. H. Ditchfield, and 

 Breconshire by Mr. Christopher J. Evans. The volume on West 

 London, while full of interesting matter, contains a repetition, of the 

 more general parts in the same author's " East London ", and the 

 section on geology is the same. The district includes St. Pancras, 

 Holborn, Lambeth, and the area to the west. There are good views 

 of High gate Ponds and Hampstead, and accounts, with pictures, of 

 some of the Museums. An index completes the work. Oxfordshire 

 contains a well- written section on geology, illustrated by good figures 

 of some fossils and view of Malmstone Quarry at Watlington. The 

 red (ferruginous) lands and iron-ore of Adderbury, Hook Norton, etc., 

 are described, also the Stonestield Slate, various Oolites, and later 

 deposits. An excellent account of the scenery is given.
