that "by a study of the hfe histories of plants and their habits of 

 behavior under different conditions of environment, we shall 

 broaden our concept of nature and cultivate our aBsthetic. 

 observational and reasoning faculties." How much more im- 

 portant this is to the student than to be possessed of a few stray 

 and disconnected facts of natural history ! Ecolog^y means study 

 in the field and is the kind of valuable nature study work so 

 heartily and ably encouraged and fostered by The Ottawa 

 Field-Naturalists' Club and the Natural History Society of 

 Montreal Atkinson's Elementary Botain- will be of great value 

 to High School Teachers and to Teachers in Collegiate Institutes. 

 It inspires the student by presenting the attractive features first 

 and trains his mind in logical methods of induction, which, as 

 the author observes, is of vast importance in its mfluence upon 

 the character of the pupil. The book is well printed, beautifully 

 illustrated and substantially bound.

This paUeontological report brings our literature and infor- 

 mation on the Hamilton formation of Ontario up to date. So

 cation and nomenclature of palaeontology of late that the revised 

 " list" given by Mr. Whiteaves, pp. 412 — 418 of this, the 659th 

 contribution or publication of the Geological Survey Departments 

 will prove of great value to all working geologists and palaeon- 

 tologists. A resume of the vaiious orders and families repre- 

 sented in the Hamilton formation of C'anada include the
