EXERCISE AND REVIEW 

 BOOK IN BIOLOGY 



By J. G. BLAISDELL 



A Combined Laboratory Guide, Notebook 

 and- Review Book for Students' Use 



TN submitting the manuscript of this manual to the 

 A publisher, the author wrote: 



"As a teacher of biology, I have for several years felt the 

 need of a laboratory guide and notebook that would lighten the 

 labor and economize the time of both teacher and pupil in con- 

 nection with their laboratory work. In this age of cheap printing 

 it seems a needless waste of time and strength to compel teachers 

 to prepare laboratory outlines and to mimeograph or copy them 

 on the blackboard, and it ought to be possible to permit the 

 pupil, when he enters the laboratory, to begin work at once with 

 his laboratory directions, questions, needed outline drawings, and 

 space for his notes and sketches all on one neatly printed note- 

 book page. I have found the loose-leaf, blank-page, ring-cover 

 notebook, and separate laboratory directions method both waste- 

 ful of time and unsatisfactory in other respects, and have used 

 careful thought and my experience as a teacher in planning a 

 tetter way." 



Mr. Blaisdell has solved the problem with this book. His manual 

 bears '.he same relation to laboratory study as a well-ordered 

 text bears to the recitation, and cannot fail to conserve the time 

 of both teacher and pupil. 



It contains 100 laboratory exercises, with space for more, cover- 

 ing a year's work in general biology, planned to meet the re- 

 quirements of the syllabus issued by the Regents of the Uni- 

 versity of the State of New York, and to accompany any high- 

 school text in general biology in common use. 



Review exercises are provided, and a series of Regents' ques- 

 tions are so arranged as to give a review of the year's work.
