I TN submitting the manuscript of this manual to the I 



I A publisher, the author wrote: | 



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



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



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



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



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



i to prepare laboratory outlines and to mimeograph or copy them | 



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



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



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 | 



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



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



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



I better way." = 



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



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



I 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- f 



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



I 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 



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. |
