DIRECTIONS FOR LABORATORY WORK 



II. Laboratory Records 



A. DRAWINGS 



1. All laboratory drawings are to be in pencil and fully 

 labelled in pencil. 



2. Outline drawings showing boundaries of structures with 

 clear cut, continuous lines (not sketched) are required except 

 Avhere finer structure is to be shown. Indicate such finer struc- 

 ture by fine dots. See Fig. B, page 14. No other kind of shad- 

 ing will be accepted. 



3. Drawings must be upon the approved paper included in 

 the Zoology I packet. Use but one side of the drawing paper. 



4. Each page of drawings should bear a general subject 

 label at the top of the page. Use care in arranging the drawings. 



5. Each individual drawing must be accompanied by a 

 descriptive label, above or below the drawing, and in addition, 

 details and individual parts must be pointed out. 



6. All labels must be written or printed parallel to the top 

 of the page. 



7. Usually the size of drawings is specified in mm. In some 

 instances, size of the drawing is indicated in terms of the actual 

 size of the object. Thus X5 means that your drawing is to be 

 five times the diameter or length of the object studied. 



8. A solid or broken line should connect each structure 

 with its special label. Study the drawing of the microscope 

 (page 11) for method of labeling. 



9. In laboratory drawings the name of a part should never 

 be written upon the drawing of the part but should be to one 

 side. 



B. NOTES 



1. Notes are to be written only where indicated by "notes 

 required." 



2. The notes are to be in ink upon the ruled paper for that 

 purpose included in the Zoology I packet. Use one or both sides 

 of the ruled paper as you maj' pi*efer.
