II. — Introductory Text-Book of Physical Geography. By the 

 late David Page, LL.D., F.G.S. Tenth Edition, Eevised and 

 Enlarged by Professor C. Lapworth, F.G.S., etc. (Edinburgh 

 and London, 1881 : W. Blackwood and Sons.) 



THE Text-book of Physical Geography by the late Dr. Page 

 having reached the tenth edition is fair evidence of its being a 

 satisfactory and useful introduction to the subject. The present 

 edition has been prepared by Prof. Lapworth, who has carefully 

 revised and enlarged it, so as to bring up the information it contains 

 to the present date. Certain corrections and additions have been 

 made throughout from information derived from the later researches 

 and speculation bearing on physics, meteorology, and biology. The 

 additional matter has been illustrated by some new maps, but no 

 changes have been made in the original textual arrangement of this 

 little treatise, which is intended to convey in a systematic manner 

 the leading; facts of the science to which it relates. J. M.

 rnHE systematic labours of the Geological Survey of England 

 _L furnish us, from time to time, with descriptions of little- known 

 districts, of which the work before us is an example. It is true 

 that, in his extended survey of the glacial deposits of the East of 

 England, Mr. S. V. Wood has drawn attention to some of the 

 sections in the country now described in detail ; but none of these 

 appear to be sufficiently fossiliferous, or to present other features to 

 tempt amateurs and to awaken controversy. The greater part of 

 the area is covered by the Chalky Boulder-clay, beneath which are 

 found certain beds of brickearth, gravel and sand, ti-aces of Reading 

 Beds and Thanet Sands, and possibly also of Crag ; while the Chalk 

 underlies all. This area is contained in Quarter-sheet 60 S.W. of 

 the Survey-map, and includes the towns of Bildeston, Lavenham, 

 Mendlesham, Needham Market, and Stowmarket. It should, how- 

 ever be mentioned that a deep well at Combs penetrated the Chalk 

 (843^ feet) to the Gault and Greensand beneath. Overlying the 

 beds before mentioned are later deposits of brickearth, gravel, and 

 sand (grouped as Post-Glacial), and alluvium. Perhaps the most 

 interesting deposit is that seen in the brickyards at Woolpit, where, 

 according to Mr. Blake, the bed, a laminated brickearth, has been 

 worked since the time of Queen Elizabeth, and furnishes excellent 

 white bricks. This deposit occurs directly beneath the Boulder-clay, 

 and in point of age may, perhaps, be compared with the bed at 

 Thetford, grouped by Mr. Skertchly with his "Brandon Beds." 

 Mr. Whitaker, however, is inclined to regard the brickearths that 

 underlie the Boulder-clay in this district as lenticular masses in 

 the gravels and sands (=" Middle Glacial" of Mr. Wood). 



A number of well-sections give additional value to this Memoir, 

 which is edited by Mr. Whitaker, although the greater part of the 

 field-work was done by Mr. Blake. i H. B. W.
