Crown 8vo. 7_s._ 6_d._ _Nature._ The geology of Cambridgeshire possesses a special interest for many students.... There is much in Cambridgeshire geology to arouse interest when once an enthusiasm for the science has been kindled, and there was need of a concise hand-book which should clearly describe and explain the leading facts that have been made known.... The present work is a model of what a county geology should be. =The Principles of Stratigraphical Geology.= By J. E. Marr, M.A., Fellow of St John's College, Cambridge. Crown 8vo. 6_s._ _Nature._ The work will prove exceedingly useful to the advanced student; it is full of hints and references, gathered during the author's long experience as a teacher and observer, and which will be valuable to all who seek to interpret the history of our stratified formations. _University Extension Journal._ Mr Marr is an old University Extension lecturer, and his book, which is distinguished by the lucidity and thoroughness which characterise all his work, cannot fail to be of service to University Extension students who are making a serious study of Geology. =Crystallography.= By W. J. Lewis, M.A., Professor of Mineralogy in the University of Cambridge. Demy 8vo. 14_s._ net.
