4. Shading should be used only when necessary to differentiate 
parts. The best method of shading is usually by stippling—that 
is, by the use of small round dots. Other methods of shading 
should be used only by advice of the instructor. 
5. The drawings should be placed on the drawing paper in such 
a way that when placed in the notebook covers they will fall on 
the right-hand page of the open book. Only one side of the 
drawing paper should be used. At the top of each plate, midway 
between the two upper corners, write the name of the animal 
described. Each plate should bear a number in Roman numerals 
in the extreme upper right-hand corner (e. g., Plate I, Plate II, 
etc.), and the student’s name in the extreme upper left-hand 
corner. The drawings of each page or plate should be numbered 
with Arabic numerals beginning with 1, e. g., Fig. 1, Fig. 2, etc. ; 
this number should be placed below the drawing. Every part of 
each figure should be named by drawing a fine, straight line from 
the part to the exterior nearest the point indicated and placing at 
its end an appropriate abbreviation in an upright position. The 
guiding lines are best made with the aid of a ruler; they may 
radiate out in all directions from the figure or be arranged in a 
parallel manner to suit the situation. All labeling should be done 
with a lead pencil; ink should not appear on the plate. 
6. Reference sheets of note paper, written in ink, should face 
each plate, bearing the words “Explanation of Plate” followed 
by the plate number in Roman numerals, on the line at the top of 
the page. On the reference sheet each figure should have a de- 
scriptive or explanatory title, full but concisely stated, giving the 
object of the drawing, condition of the material, position and 
point of view, enlargement, etc. At the close of the list of titles 
give an alphabetical list of the abbreviations used, with their 
meaning. 
7. If any of the above points are not clear to you, consult a 
sample notebook which will be provided. 
D. Corrections.—1. At intervals throughout the term’s work 
you will be directed to place all drawings, reference sheets and 
notes of whatever kind you wish criticized, in one of the “ Hand- 
in Envelopes,” in the proper order, the first page facing the back 
of the envelope, and submit them to the instructor for criticism.
