I By J. G. BLAISDELL 



I 



A Combined Laboratory Guide, Notebook 

 and Review Book jor Students' Use 



N submitting the manuscript of this manual to the 

 publisher, the author wrote: 



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



= need of a laboratory guide and notebook that would lighten the 



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



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



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



I to prepare laboratory outlines and to mimeograph or copy them 



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



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



I his laboratory directions, questions, needed outline drawings, and 



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



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



I notebook, and separate laboratory directions method both waste- 3 



I ful of time and unsatisfactory in other respects, a.nd have used | 



I careful thought and my experience as a teacher in planning a | 



I tetter way." | 



§ = 



I Mr. Blaisdell has solved the problem with this book. His manual 5 



I bears '.he same relation to laboratory study as a well-ordered 5 



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



i of both teacher and pupil. | 



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



I jng a year's work in general biology, planned to meet the re- | 



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



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



I school text in general biology in common use. | 



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



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