II. — The Coal Fields of GrLOTJCESTEKSHiEE and Somersetshire, 

 AND their Resources. By John Anstie. pp. 103. (London : 

 Stanford, 1873.) 



THIS work is devoted to a description of the Coal-basins between 

 Tortworth and the Mendip Hills, familiarly known as those of 

 Bristol and Eadstock, Nailsea, and Clapton-in-Gordano. The last- 

 mentioned is hardly deserving of such prominence, were it not for the 

 discovery made known by Mr. Richardson of Coal-measures beneath 

 the bed of the Severn, west of Almondsbury, which may possibly 

 be connected with the exposures of Coal-measures at Portishead 

 Point and Clapton. 



Mr. Anstie gives detailed descriptions of the Coal-strata and of 

 the structure of the basins with their many faults and disturbances. 

 He has endeavoured to correlate the seams developed at the different 

 mines — a feature which may be said to characterize the volume. 

 This has not been attempted so thoroughly before. He points out 

 the probable further extension of the Coal-measures, and states his 

 estimate of the resources of the known area. The bordering rocks 

 are briefly alluded to, and the work, which is essentially a practical 

 one, is illustrated by nine plates of sections, both horizontal and 

 vertical. H. B. W. 



Ill- — The School Manual of Geology. By the late J. Bebte 

 Jukes, M.A., F.-R.S., for many years Director of the Geological 

 Survey of Ireland. Second edition, edited by Alfred J. Jukes- 

 Browne. 8vo. (Edinburgh: Black, 1873.) 

 TEN years have elapsed since the late Prof. Beete-Jukes brought 

 out his ' School Manual,' which may be regarded as one of our 

 best introductions to the science of Geology. This period, short as 

 it may seem, has witnessed considerable progress in the different 

 branches of the science ; and to keep acquainted with all the results 

 of geological investigation becomes every year a more difficult 

 task. This new edition of Mr. Jukes's little work, which has been 

 prepared by his nephew, seems worthy of its predecessor : the old 

 matter has been carefully revised, and much that is new has been 

 added. It may be difficult in an elementary work to decide as to 

 how much detail to insert ; some notices, however, of the North- 

 ampton Sand, Speeton Clay, and of the Gravel beds and great chalky 

 Boulder-clay of the Eastern Counties might, we think have been 

 given with advantage. Nevertheless, omissions such as these will 

 not detract from the value of the book, which after all is not to 

 describe the geology of a country, but to expound in an elementary 

 form the leading principles of the science. This being the case, 

 we gladly recommend it.

THIS useful contribution to geological literature has now reached 

 the tenth volume, and is equally creditable to the editors for 

 the care and attention paid to its production as are the preceding
