ical sense. It will be noted, however, that no attempt is made 
here to distinguish technical terms and technical names by the 
use of a different type, since it is believed that a rational nomen¬ 
clature is nothing more than the most exact form of scientific 
language, and should be learned and used by the student as a 
language, rather than as a set of terms and names. Following 
this idea it is frequently found advisable to introduce the name 
of a structure or feature without information as to its exact loca¬ 
tion, when that name is such that the thoughtful consideration 
T)f its meaning on the part of the student will suffice to show its 
application; and it is my opinion that every effort should be made 
to induce the student to rely upon his own knowledge of Latin and 
Greek, as well as English, to help him in understanding and 
applying new terms. 
In many parts, the outline consists rather of a memorandum 
of the structures and relationships to be studied than of a set 
of definite directions for work, to be blindly and implicitly fol¬ 
lowed. This is the intentional expression of the feeling that, 
in the matter of dissection and study, the sooner the student learns 
to rely upon his own judgment and ingenuity the better, and that, 
under proper restrictions, individuality in the method of working 
should be developed even at the occasional expense of time and 
material. 
With regard to the method of recording the work done in the 
laboratory, it cannot be too strongly or too frequently empha¬ 
sized that such records, whether in the form of notes or draw¬ 
ings, are wholly for the student’s own personal use, and that 
with him lies the whole responsibility for their accuracy. They 
can have no value except as an expression of what the student 
has learned from his own study of laboratory material, and 
they should be as individual in their form as are the students 
themselves in their methods of study. Laboratory drawings, 
to express the true scientific attitude, should be in the nature of 
working drawings rather than of finished productions, and 
should be left in a sufficiently plastic form to admit of modifica¬ 
tions and additions, if at any time a more accurate or complete 
knowledge of the object is obtained. Thus, while drawings 
should be neatly executed and labeled, for a student to labor for
