C. THE CAVITIES OF THE BODY AND THEIR CON¬ 
TENTS, THE “ VISCERA.”

white rats or cats) Cf. with anatomical manikins of the human 
body. 2 
General Directions for Making Scientific Drawings.— All 
drawings should be oriented upon the page either with the anterior 
or the dorsal region of the part drawn uppermost; they should be 
made with careful attention to proportions and upon a sufficiently 
large scale to show clearly all of the structures studied. Use a 
well-sharpened hard (2H or 4H) pencil and draw with light 
trial lines which may be readily erased and changed as the work 
progresses; let every line which is finally left express a definite 
idea, and finish the drawing in pencil in clear-cut, definite, but 
never heavy outlines. Ink is inadvisable, and shading is in gen¬ 
eral ineffective and is for beginners, at least, a waste of time. 
J If rodents are used, they should not be fed for several hours previous to chloro¬ 
forming. The specimens used for this study of the viscera may be kept in good 
condition in a considerable volume of running cold water for 24 hours. Subsequently 
they may be preserved for further study in 5% formalin. Because of the irritating 
properties of formalin, however, material preserved in this way should be thoroughly 
washed out in running water for several hours before it is used. 
2 A very convenient model for comparison of this dissection with the human 
body is found to be that of the torso in the position for dissection, showing the 
thoracic and abdominal cavities and their contents.
