Geological Guide to the Island. Basing his views upon the ex- 

 cellent works of Mantel], Forbes, Bristow and others, Mr. Norman 

 has incorporated in his volume many descriptive notes and sugges- 

 tive observations, the result of thirty years' experience and work 

 amongst the Downs and Coast sections of his interesting district. 

 Each geological formation is reviewed in turn, and lists and 

 illustrations of the principal fossils given. Notes on the best 

 collecting grounds, and much information of an instructive and 

 useful kind, both to the collector and visitor, as well as to amateurs 

 and students, will also be found in his pages. After reviewing the 

 various divisions in ascending order, Mr. Noi'man devotes one 

 chapter to the consideration of '• Denudation and Landslips," and 

 another to " The Human Period." In an appendix he discusses " the 

 Eelation of the Geology of the Isle of Wight to that of the Isle of 

 Purbeck." Some notes on the Ventnor Museum and a list of the 

 Economic Products of the Island complete the volume. 



Although the book is essentially a Geological Guide, Mr. Norman 

 has rendered it useful to other visitors, for he points out the most 

 interesting features in the landscape, and gives much general infor- 

 mation touching the antiquities of the Island and other objects. 



A map, sections, and fifteen plates of fossils accompany the text, 

 and we must congratulate the author on having so careful a draughts- 

 man as his friend Mr. Eyan, the plates being much superior to those 

 usually seen in Guide-books. Several typographical errors on the 

 plates and others in the text seem to have escaped the notice of the 

 author. The numerous plates and figures together with the low 

 price should recommend this book to all, and it should especially 

 find a place in the equipment of the tourist and the visitor, who is 

 interested in the Geology of the Isle of Wight.

 Society of Canada, Section iv. 1886.] 



IN his brilliant Memoirs on the Moffat Series and the Girvan 

 Succession, Professor Lapworth completely established the high 

 importance that should be attached to the study of life-zones for the 

 elucidation of the true sequence of fossiliferous rocks. Wherever 

 these rocks are contorted into frequent foldings and their original 

 position disturbed by faults, stratigraphical evidence alone can 

 seldom be relied upon to assign them their place in the series. In 

 such cases the testimony afl:brded by fossils even of such lowly 

 organization as that of the Graptolites becomes of almost incalculable 

 value. 



In complicated areas such as those of the Girvan District, the 

 eastern townships of Lower Canada, and the regions treated of in 

 the Eeport now before us, a minute and patient investigation of the
