nental authors have supplied much new matter of late years in the 

 various branches of palseoutology ; and M. Bernard has largely 

 availed himself of these additions to science. English -works have 

 also been used to some extent ; but some improved views have been 

 neglected — such as A. S. Woodward's determination of Ptycliodvs as 

 a Batoid or Eay, W. Hind's elucidation of Anthracomya and Anthraco- 

 ptera, &c. ; and the division of the Batrachians from Eeptiles as 

 Amphibia is ignored. 



On the other hand, great pains have been bestowed on various 

 important subjects, such as the character, development, and classifi- 

 cation of the Ammonites (pages 639-677, with upwards of thirtj' 

 illustrations, in many instances composed of several figures). 



The Author has more especially kept in view the relationship of 

 PaliTontology with Biology, and has thus dealt with generic rather 

 than with specific forms, except in the case of unique or very rare 

 fossils, such as Arclioopteryx and Triceratops. The comparison of 

 the fossil with recent animals and plants has been carried out, as far 

 as practicable, with respect to their morphology, intimate structure, 

 and embryological development, thus aiming at the improvement of 

 their classification. 



The Author gratefully acknowledges the kind help received from 

 Munier-Chalmas, Boule, Filhol, Haug, (Ehlert, Eenault, Steinmann, 

 Gaudry, Eemy Perrier, and the late Dr. Fischer ; as well as the 

 advantages he has had from the information found in the several 

 large manuals of Palaeontology by Steinmann and Dciderlein, by 

 Nicholson and Lydekker, and especially the treatise by Zittel. To 

 the last he refers students for bibliographic references previous to 

 its publication ; while those of later date are mostly to be found in 

 the test and footnotes of the book before us. 



The Index for the whole volume fills twenty pages, with three 

 columns of small print in each, indicating by different printer's 

 types the names of genera separately from those of families and 

 orders, and from those of classes and divisions. 



In whatever respects M. Bernard's book and teaching may difi'er 

 here and there from the views of other palaeontologists, and what- 

 ever the shortcomings in printer's and author's errata, he has done 

 good service in producing a comprehensive and philosophical elabo- 

 ration of what is known about fossil animals and plants, clearly 

 expressed, excellently well illustrated, and enriched with refer- 

 ences to many original workers and thinkers.
