PLATE XXXI 



Plate XXXI represents a projection of the same struc- 

 tures upon the left lateral surface of the body, also re- 

 duced to one-half life size. The OO line in this plate is 

 the left midaxillary line. 



The measurements for the lateral projections were made 

 in the same way as for the anterior and posterior, using 

 the midaxillary plane instead of the midplane. In this 

 case, however, it was not necessary to make corrections 

 for the obliquity of the surfaces, except in one or two 

 cases. Each organ is outlined in the same character of line 

 in the lateral projections as in the anterior and posterior 

 projections. 



The ruled lines of the green background in Plates 

 XXVIII to XXXI represent the millimeter spaces on the 

 life size chart, reduced to the same scale as the figures.
