4-50 Progi-ess of Geology, 



ments. This map has been since engraved upon a reduced 

 scale, with the advantage of possessing most of the principal 

 observations made during the last ten or twelve years ; and, 

 notwithstanding some obvious minor defects, as a guide to the 

 scientific English traveller, cannot be too highly commended. 



Mr. Farey completed an elaborate mineral ogical survey of 

 Derbyshire, and was long an active contributor, through 

 various channels, towards the promotion of a science to which 

 he was zealously attached. 



It were injustice to the memory of Mr. Parkinson to pass 

 unnoticed his Organic Remains of a former World, which 

 appeared in 1808; the earliest (except the Fossilia Han- 

 toniensia of Solander and Brander), the most elaborate, and 

 certainly the most magnificent, work that issued from the Bri- 

 tish press, in illustration of a department of natural history 

 then little understood. This, and a subsequent Introduction 

 to the Study of Organic Remains, have placed their author in 

 the first class of naturalists. But English geology at that 

 period was quite in its infancy. Little was known of dis- 

 tinctions in strata; and, as the fossils were classed without 

 regard to geological arrangement, the utility of the work was 

 considerably lessened. Of this imperfection the author ap- 

 pears to have been aware in his preface to the concluding 

 volume. 



The unavoidable deficiencies here alluded to have been, in 

 a great measure, supplied by Mr. Sowerby's Mineral Concho- 

 logy of Great Britain, The first portion of the work had also 

 the disadvantage of appearing before the nomenclature and 

 true position of the formations were determined; a circum- 

 stance which has disturbed the uniformity of the plan, but 

 which a carefully compiled general index, or rather a good 

 series of indexes, will materially rectify. This unrivalled pro- 

 duction, commenced in 1812, and continued to the present 

 time, does honour to the name of this distinguished naturalist 

 and his sons, and will long remain among the most useful, as 

 it is one of the most splendid, acquisitions to the science it so 

 beautifully illustrates. 



Mr. Bakewell published a useful Introduction to Geology in 

 1813, the third edition of which has been recently printed, 

 comprising much valuable additional matter. The views of 

 this gentleman on some points relating to the arrangement of 

 rocks, and their analogies to Continental formations, differ 

 somewhat from those currently adopted by English geologists, 

 but demand all the respect to which so experienced an autho- 

 rity is entitled.
