3\o. 489] NOTES AND LITERATURE 



tiling more than twenty species of vertebrates and invertebrates, 

 together with questions, tlic majority of which appear to be answered 

 by the context, the remainder by the companion text book.^ Tins 

 method scams to us unwise and the book is apparently less useful than 

 Kingsley's Elements of Compamiive Zoology (2nd. ed., Henry Holt 

 -and Co., 1904). The latter is a cheaj>er book which gives facts that 

 are otherwise inaccessible to the student and asks questions which 

 can be answered witliout appeal to costly apparatus, about easily 

 obtained and inexpensive animals. The answers, the student must 

 gather while learning both to find and arrange facts and to draw right 

 conclusions. A more extensive work is that of Linville and Kellv; 

 their Text Book in Geneial Zooloqij and Guide jo- Lahomfonj and Field 

 J\ oik VI Zoolofji/ (Ginn and Co , 1906) gi%e facts and suggestions, 

 especially tor the reading of original articles, together with necessary 

 deductions; and ask most interesting and suggestive questions which 



of any of these books will give the student about the same facts, but 

 Klng^le^, and LiiniUe and Kellx, compel the student so far as a book 

 can do so, to observe and think, which is the most desirable service 

 to the memory-laden vouth. It reallv makes little difference how 



method of stuch^is of primarv importance.
