In this table there is agreement in the subdivision of the Miocene 

 with the series adopted in the British Museum Guide (before- 

 mentioned) : elsewhere harmony does not prevail. M, Lemoine gives 

 a tabular statement to show the classifications adopted by different 

 geologists, but it does not give all groupings such as those of Renevier 

 (1897). It is desirable that some system of nomenclature be generally 

 adopted, although none can be perfect. The stratigraphical divisions 

 that would be represented on a geological map vary from place to 

 place, and they have an independent practical as well as scientific 

 importance. Chronological divisions should be based on localities 

 where the fauna and flora are well represented. 



The Quaternary deposits are grouped as follows : — 



T>^^^^, / A 4. ^\\ Period of Metals. 

 Eecent (Actuel) j NeoiitMc. 



/-"Upper : Epoch of Eeindeer. Magdalenian. 



Middle : Epoch of Mammoth with Rhinoceros 

 ticJiorhinus, etc. Moustierian. 



Lower : Epoch of Hippopotamus with Elephas 

 antiqiius, etc. Chellean (first indis- 

 putable remains of Man in Europe). 



The latest stage of the Pliocene is noted as the epoch of Cephas 

 meridionalis, with Rhinoceros etrtiscus and JSquus stenonis ; and it is 

 bracketed, with a query, under Palseolithic. 



The concluding chapters of this work deal with geomorphology and 

 give a general summary of results. There is a copious bibliography, 

 but it contains no reference to any of Prestwich's works. There are 

 good indexes of species and localities, and a full table of contents.
