tho relative ogcs of the Boulder clays of East Anglia and those of the 

 N. of England and of Scotland, are discussed. The author thinks that 

 the Pala3olithic implements found at Brandon and other places in the 

 Eastern counties are of Interglacial age ; for, although some are found 

 above the Chalky Jioulder Clay, yet this deposit is much older than 

 certain glacial deposits of the N. of England and of Scotland. The 

 character of the changes during the Glacial period is discussed.

This seam ranges from Leeds to beyond Sheffield. It rests generally 

 on ganister, and contains nodules of pyrites and carbonate of lime. It 

 is followed by marine beds, but preceded by freshvrater beds with 

 Anthracosia, which also occurs in the Middle Coal Measures (above). 

 The oscillations thus indicated are described, and the range in time of 

 the Cephalopoda alluded to. W. H. D.

Points out that the junction between the Old Red Sandstone and 

 Carboniferous rocks is so gradual that it is impossible to say where one 

 ends and the other begins. Describes some of the more remarkable 

 faults and disturbances in the Carboniferous rocks. Gives a particular 

 account of the section in the Avon cliffs, with lists of fossils. The 

 species from the L. Carboniferous shales are compared with those from 

 the U. Devonian strata of N. Devon, and from the L. Carboniferous 

 beds of Ireland and Scotland. Analyses are given of the ha3matite- 

 ores from Clifton, Ashton, and Winford. A general list is given of the 

 principal fossils from the Carboniferous Limestone of the district; — the 

 localities cited being Cheddar, Portishead, Ilenbury, Weston, Clevedon, 

 and the Mendip Hills generally. The Millstone Grit and Coal Mea- 

 sures are described, and a list of fossils from the Pennant Sandstone is 

 given. The formation of coal is briefly treated of, and its production
