130 Reviews — The Grimaldi Caverns. 



None but those who have handled similar material can have any 

 idea of the vast amount of work of the highest class concealed behind 

 the unpretentiousness of this superb monograph. President Osborn 

 expresses his acknowledgments to his colleagues, Gidley, Granger, 

 and Matthew, to the published work of niany other American 

 palaeontologists, to Professor J. C. Merriam, to his assistant, 

 Miss Ripley, and to the artists, Messrs. Oka and Yoshihara, and 

 Mrs. Stirling. 



This memoir represents the result of " team work " by eminent 

 students fused into one by that palaeontologist whose studies have 

 gradually established those philosophical principles on which 

 modern methods of palseontological investigation very largely 

 depend. It provides a triumjohant vindication, had one been 

 necessary, of the soundness of the policy adopted by Professor 

 Osborn of sending out on collecting expeditions year after year 

 those palaeontologists who are going to work up the material 

 acquired. Only in this way is it possible to attain that certainty 

 of horizon Avhich is essential for satisfactory work. Had dependence 

 been placed on the j)urchase of collections and on the sporadic 

 gatherings of geologists, this work would have forever remained 

 impossible, because the zonal classification, probably the most 

 detailed and satisfactory one known, could not have been worked 

 out and the horizon of any specimen would alwaj^s have been open 

 to doubt.

The Grimaldi Caverns. 



Les Grottes de Grimaldi (Baousse-Rousse). Tome I, Fasc. IV : 

 Geologie et Paleontologie [fin.). By Marcellin Boule. 

 pp. 237-362, pis. xxx-xh. Monaco, 1919. 



T)ROFESSOR BOULE is to be congratulated on the completion 

 -*- of his important work on the remains of vertebrate animals 

 found with man in the caverns of Grimaldi on the south coast of 

 France. It is not merely a technical treatise on fossil bones and 

 teeth, but also a general discussion of the Pleistocene mammalian 

 fauna, of very wide interest. The final instalment deals with the 

 Carnivora, Insectivora, Cheiroptera, and Rodentia, besides more 

 fragmentary remains of birds, reptiles, and amphibians. It then 

 ends with a summary of the results. 



Professor Boule points out that the succession of a warm fauna 

 {Elephas antiqmts, Rhinoceros merchi, Hip-popotamus, etc.), a cold 

 fauna (glutton, ermine, marmot, reindeer, etc.), and then the modern 

 fauna, is as clear in the low latitude of the French Riviera as in the 

 rest of Central and Western Europe. He correlates the first (or 

 Chellean) period with the third interglacial period of Penck, and 

 the following (or Mousterian) period with the Wiirmian glacial 

 episode of Penck. He adds maps showing the geographical
