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.

 MARK, M.A., Fellow of St John's College, Cambridge.

 as a teacher and observer, and which will be valuable to all who seek to 

 interpret the history of our stratified formations.

 the completion of a treatise worthy of the subject and of the University.
