physical and geological maps, colour-printed. The price is Is. 6d. In 

 size the Tolume on Kent occupies 146 pages, that on Cambridgeshire 

 271 pages. In the latter, as might be expected, we have not only 

 a concise account of the Geology and Soil, leading up to the Natural 

 History and the introduction of the plants and animals, but a much 

 fuller account than in other volumes of the Antiquities from 

 Palaeolithic times and of the Architecture. Although the Soil is 

 mentioned, but little is said about it except in reference to Forestry, 

 and the relations of the geology to Agriculture are not dealt with. 

 Among special cultivations in Cambridgeshire that of woad is 

 interesting, the plant Isatis tinctoria being still grown for dyeing 

 purposes, and an illustration is given of the Woad Mill at Parson's 

 Drove, Wisbech. 



The article on the Geology and Soil of Kent is not very satisfactory : 

 the Thanet Sands are not "quite destitute of fossils", nor are the 

 septaria in the London Clay of Sheppey "nodules of carbonate of 

 lime and iron pyrites". The Oldhaven Beds mentioned on the map 

 are not referred to in the text, the Thanet Beds are not mentioned in 

 the legend to the map, while the Bracklesham Beds there noted, do 

 not occur in Kent. 



Good accounts of the geology and the soils and of the mines and 

 minerals are given in the geographies of Fifeshire and Ayrshire. 



There is no question that the series is an attractive one, and will be 

 widely appreciated. 



VI. The Kelvingrove Museum, Glasgow. — Introductions to the 

 study of minerals and of rocks, including Guides to the respective 

 collections in the Museum, have been prepared by Mr. Peter 

 Macnair, F.E.S.E., the Curator of the Natural History Collections 

 (8vo; Glasgow, 1910 and 1911; price 3d. each). The Guide to the 

 Mineral Collections is illustrated by a plan of the Gallery where the 

 specimens are displayed, by various forms of crystals, and by a plate 

 depicting pseudomorphs of Gaylussite, dredged from the Clyde at 

 Cardross. Curiously enough this mineral is not mentioned in the 

 index, although briefly described on p. 63. The Guide to the llock 

 Collections is more fully illustrated with plan, pictorial views of rocks 

 in the field, photographs of rock-specimens, micro-sections of rocks, 

 and diagrams of the crystalline forms of rock-making minerals. 

 These handy Guides should prove very helpful to students.
