observations and of the conclusions arrived at, in such a way 

 that the memory may be readily refreshed concerning them. 



Students should look to the teacher for inspiration as to 

 the proper spirit with which to regard their work. Many 

 times the reason why particular attention is paid to certain 

 things may not be apparent, but this should furnish no 

 excuse for not carrying the work through thoroughly as 

 directed. If the reason is obscure at the time, we should 

 have perfect confidence that it will be revealed later on ; as 

 the work proceeds, the plan underlying it will unfold itself, 

 and we shall finally find ourselves in possession of the whole 

 and recognize the value of each of its parts. We should en- 

 trust ourselves to the teacher's guidance with perfect faith 

 that all which now seems dark and hidden will be cleared 

 away before the course is completed. 



Instruments. Few instruments are absolutely necessary 

 for the work planned in this book. The pupil should, how- 

 ever, possess the following : 



Laboratory note-book, 



Pencils and eraser, 



Pair of small forceps, 



Scalpel or penknife, 



Pocket lens or dissecting microscope, 



Pair of needles in handles. 



Note-Book. The note-book should be of fair size. One 

 with a page about 10 inches long and 6 to 8 inches wide is 

 preferred by the writer. The paper should be white, un- 

 ruled, fairly heavy, and with sufficient gloss to take the mark 

 of the pencil readily, but not so much so, as to make erasing 

 difficult. 



Pencils. A fairly hard pencil should be used, certainly 

 hard enough so that it will be possible to keep it well
