The Laboratory Note-Book. 



For Students using any Chemistry. 4^ by 7% inches. Board covers. 

 Cloth back. 192 pp. Price by mail, 40 cts.; Introduction price, 35 cts. 



IT contains blanks for experiments ; blank tables for the reactions of 

 the different metallic salts : pages for miscellaneous matter ; and an 

 extra chart for the natural classification of the elements similar to that 

 on page 221 of Shepard's Chemistry. This may be rolled into a 

 cylinder by the student. 



The advantages of using this note-book are, briefly, these: It saves 

 time for the student ; its size is convenient : and it is cheaper than an 

 ordinary blank-book. The paper is such that it readily takes ink with- 

 out blotting or smearing, and it may be used with a lead pencil. 



The value of systematic note-taking by the student in chemistry can 

 hardly be over-estimated. The careful analyst habitually keeps record 

 of his work, and thus the greater portion of our most valuable chemical 

 literature has originated. If the expert finds his notes to be of ines- 

 timable value to him. what shall we say in the case of the beginner? 

 Evidently, that he should form, at the very outset, those habits which 

 will tend to make him accurate, and which will insure his after-success. 



In the note-book the teacher has a most potent ally ; for, through its 

 aid, he may know just how his students are doing their work, and can 

 therefore better adapt his teaching to their needs. 



Our Special Circular contains fac-similes of three pages, prepared 

 by the students in the Ypsilanti high school for 1885-6, showing how 

 the book is to be used.

Purdue Univ., Lafayette, hid. : It strikes 

 me very favorably. I think further ex-

 Purdue University next fall. (Apr. 24, '86.)
