 Mr. C. 1). Waloott ; L. \V. Bailey and W. Molnnes on portions 



of northern New Brunswick and adjacent parts of Quebec and

Messrs. Bailey and Mclnnes illustrate in their report the paleo- 

 zoic geology of northeastern Maine, and apppear to show that 

 the rocks of this part of Maine in Aroostook Co. are LTpper Silu- 

 rian rather than Devonian, which they are made in the Geological 

 Reports on Maine. 



4. Manual of Paheontolof/}/, for the use of Students, with a 

 1 Introduction on the principles of P< deontology ; by 

 Henry Alleyne Nicholson, F.G.S., Prof. Nat. Hist. Univ. of 

 Aberdeen, and Richard Lydeker, B.A., F.G.S. 3d edit, re- 

 written and greatly enlarged. 2 vols, of 1624 pages. Edinburgh 

 and London. (Win. Blackwood <fc Sons.) — The title page says, 

 "greatly enlarged ;" expressed in figures the enlargement is from 

 1040 to 1624 pages, or more than one-half; and this increase in 

 size indicates very imperfectly the actual additions in new matter 

 and illustrations. It is, as the authors claim, essentially a new 

 work. The part on the Invertebrates, covering 775 pages, has 

 been prepared by Prof. Nicholson, and that on the Vertebrates, 

 600 pages, by Mr. Lydekker, the author of reports connected 

 with the Geological Survey of India on the fossil Vertebrates ; 

 and about 100 pages on fossil plants are by the joint authors. 

 The classification follows mainly the latest authorities, and 

 the descriptions are full and present a judicious review of 

 recent opinions in cases of doubt, besides having, after each sub- 

 ject, a table of references to publications. We should separate the 

 Trilobites from the Crustaceans, and make some minor modifica- 

 tions ; but these are points about which there is reason for differ- 

 ence in judgment. Excellent figures are in profusion, representing 

 often the interior structure as well as exterior forms, and some 

 are from new observations by the author. This manual is the 

 only one of the kind in the English language and will be found 

 of great value by teachers and students in geology or paleon- 

 tolgy. Prof. Nicholson's personal work in America supplied him 

 with part of his facts, and has enabled him to appreciate and use 

 American sources of information. The volumes are made attrac- 

 tive also by the very liberal style of publication.
