N December last we drew attention to the publication of Part I of 
this work, and we are glad to note that a copious index is 
promised at the conclusion of the fourth part. The work is a more 
or less complex one, dealing sometimes with the geology of particular 
counties, at others with irregular districts, and again with particular 
formations in certain areas. The whole has been most carefully 
edited by Messrs. Monckton and Herries, whose task must have been 
no light one. The records of previous excursions made by the 
Geologists’ Association form the basis of the work, and there are 
abundant references to the published proceedings, although the 
names of the responsible directors of excursions are not always 
indicated. 
In the present part, ‘‘ Berkshire and part of the Thames Valley ” 
forms the subject of an article by Mr. H. J. Osborne White. He deals 
with strata from the Oxfordian to the Alluvial deposits. A useful 
sketch-map is given of the neighbourhood of Faringdon, showing the 
position of the pits in the famous sponge-gravel beds of the Lower 
Greensand. 
‘North Kent and adjoining parts of Surrey” are next described by 
Mr. A. L. Leach, who, after a brief reference to the Chalk, the 
Chislehurst Caves and Dene-holes, describes the principal sections in 
the Eocene strata, notes the Pliocene Beds of Lenham and elsewhere, 
and concludes with a short account of the superficial deposits and 
successive types of stone-implements. 
““The Chalk Cliffs of Kent and Sussex and the Tertiary Beds of 
Herne Bay”’ are described by Mr. G. W. Young, with due references 
to the labours of Mr. Whitaker and Dr. Rowe, in whose footsteps 
Mr. Young has so successfully trodden. 
«The Tertiary and Post-Tertiary Deposits of the Sussex Coast” 
are dealt with by Mr. J. V. Elsden. Newhaven, Bognor, and Selsey 
Bill come in for notice in connexion with the Eocene strata, while the 
Coombe Rock and other superficial deposits are discussed. The author 
remarks that the bottom of the Arun Valley is now considerably below 
sea-level. 
‘‘Hampshire and the Bagshot District’ come into the appropriate 
hands of Mr. Monckton and Mr. Osborne White, who deal with the 
Chalk and Kocene, and especially with the Bagshot, Bracklesham, and 
Barton Beds. 
‘“‘ Wiltshire ”’ is described by Mr. H. B. Woodward, who gives brief 
accounts of the famous sections in strata that range from Lias to 
Purbeck and Wealden, and from Lower Greensand to Chalk and 
Eocene, with superficial deposits of much interest. Reference is 
made to Mr. Harmer’s ‘ Glacial Lake’ in the Trowbridge Basin. 
‘The Paleozoic Rocks of Gloucestershire and Somerset’? form the 
subject of an article by Professor 8. H. Reynolds, who has added so 
much to our knowledge of the Tortworth Silurian area, and has 
discovered fossiliferous strata, probably of Llandovery age on the
