568 Reviews — Nicholson's Manual of Palceontology. 



is also an excellent zoologist and palaeontologist ; added to which, 

 he has had more than ten years' experience as a teacher of students, 

 and has thus been brought face to face with the needs of his class. 

 Neither is Prof. Nicholson a mere " prentice-hand " at the writing 

 of Text-books. Already he stands credited with : — 



1. " A Manual of Zoology." 



2. " A Text-Book of Zoology." 



3. " An Introductory Text-Book of Zoology." 



4. " Outlines of Natural History for Beginners." 



5. " Examinations in Natural History." 



6. " Introduction to the Study of Biology." 



7. " The Ancient Life-History of the Earth ; " and 



8. "A Manual of Palaeontology " (already in its 2nd edition). 

 The first edition of Nicholson's Manual of Palaeontology, which 



appeared in 1872, was contained in a single volume of moderate 

 8vo. size, numbering 600 pages, with 400 woodcuts. The present 

 edition occupies two handsome 8vo. volumes, consisting of 1070 pp., 

 with 722 woodcuts, and is so largely re-written and augmented, that 

 it forms to a great extent a new work. 



The First Part (embracing 6 chapters and 94 pp.) is devoted to a 

 General Introduction to Palaeontology in connexion with Strati- 

 graphical Geology. 



From this we are led on in Part II. (Palaeontology) to consider 

 group by group the several divisions of the great Invertebrate sub- 

 kingdom from the Protozoa to the Lamellibranchiata, their general 

 characters and their distribution in time, and the literature of each 

 division. This occupies 17 chapters and 417 pp., and lands us at the 

 end of vol. i. 



The Invertebrata extend through the first 100 pp. of vol. ii. 

 including the Gasteropoda and Cephalopoda, and with chapter xxix. 

 commences the Vertebrata — treated much in the same fashion, giving 

 to each order its distribution in time as well as its general characters. 

 This portion of the work occupies 20 chapters and pp. 826. 



Part III. is divided into four chapters on Palaeobotany, and fills 

 50 pages, treated very briefly, but in a similar manner to the 

 previous divisions. 



The volume ends with a Glossary and Index. 



One important feature of the work is its illustrations, more than 

 700 in number, which are very excellent ; a few (as invariably 

 happens in so large a work) had better, however, have been omitted 

 — as, for example, fig. 212, labelled Mamas Barriensis, and the 

 singularly crafty-looking, but decidedly stuffed, Myrmecobius fasciatus 

 (fig. 600). 



Hundreds of the figures are of the highest merit as wood en- 

 gravings, and many appear for the first time, being engraved ex- 

 pressly for this work by Mr. Charles Berjeau. 



Each Order has its diagnostic characters printed in italics at the 

 commencement of its own chapter ; and at the end of each will be 

 found a copious list of references to works and authorities who have 

 specially treated upon the group just summarized.
