 i2mo, $1.20, 



Combines laboratory work with a sufficient amount of 

 descriptive text to meet the requirements of schools and col- 

 leges that have a limited time for the subject. The compara- 

 tive feature is made especially prominent. Not only are the 

 observing powers of the learner trained in the laboratory work 

 by questions, wherever feasible, instead of direct information, 

 but his thinking powers also are cultivated by attention to the 

 correlation of facts. Most of the forms studied in detail are 

 obtainable in all parts of the country, and the book does not 

 require the use of compound microscopes. 



George Macloskie, Professor in [ S. H. Gage, Professor in Cornell 



Princeton University : — It comes 

 nearer to being the ideal text- 

 book for beginners in zoology than 

 •iny other book known to me. [In- 

 troduced.] 



R. H. Cornish, Girls' High 

 School, New York City : — This 

 book seems very clear-cut in its 

 plan and a very good combination 

 of laboratory manual and descrip- 

 tive zoology. [Introduced.] 



Sidney I. Smith, Professor in 

 Yale University : — The plan of 

 asking questions to be answered 

 by examination or dissection of 

 animals themselves is, I think, a 

 great improvement on the usual 

 directions for dissection without 

 questions. For a course of in- 

 struction similar to that proposed 

 it is the best text-book with which 

 I am acquainted. 



D. S. Kellicott, Professor iti 

 Ohio State University , Columbus: — 

 This one, I have no hesitation in 

 iiaying, isthe best thus far for high 

 schools. Of course its matter is 

 reliable and up to date. 



Francis E. Lloyd, Professor in 

 the Teachers' College, New York 

 City : — I regard the book as a de- 

 cided improvement upon most of 

 the shorter text-books, if not all. 



University: — Dr. Kingsley's train- 

 ing and original work would lead 

 one to expect a good book, and this 

 seems to fulfill the expectations. 



B. F. Eyer, Topeka {Kan.) 

 High School: — I am more than 

 pleased with Kingsley's Zoology. 

 1 have never seen a better one 

 that embodies both the text-book 

 and the laboratory idea. 



Edward M. Shepard, Professor 

 in Drury College, Springfield , Mo.. 

 — The treatment of the subjects 

 and the selection of the laboratory 

 material make it, in my estima- 

 tion, an ideal text-book. 



Charles L. Ediwards, Professor 

 in the University of Cincinnati : — 

 The lucid treatment with freedom 

 from padding, the new illustra- 

 tions and the addition of labora- 

 tory guides make the book for 

 beginners the best comparative 

 zoology I know of. 



Grace F. Ellis, Central Higk 

 School, Grand Rapids, Mich.: — I 

 have no hesitation in saying that 

 I like it better than any other text 

 wiih which I am acquainted for 

 high school work. It's outlines 

 for laboratory work are excellent 

 and the suggestions to teachers 

 unusually practicable.
