PLATE XXVIII 



Plate XXVIII represents a projection of the various 

 internal organs upon the anterior surface of the body re- 

 duced to one-half life size. The body outline was obtained 

 by enlarging to life size, with a pantograph, the photo- 

 graphs used in making Plates XXVI and XXVII. The 

 errors of proportion produced by the photographic lens 

 were corrected by measurements of the body at the surface 

 of each section. The section lines seen in Plate XXVI are 

 represented in this plate by the horizontal black lines 

 which run across the body. The exact position of these 

 lines was obtained by placing the sections one upon the 

 other in their proper position as was done to take the 

 photographs shown in Plates XXVI and XXVII. A meter 

 stick was then placed perpendicularly, parallel to the anter- 

 ior midline of the body and the position of the upper sur- 

 face of each section was measured by running a straight 

 edge horizontally outward from the section to the meter 

 stick. 



The vertical line marked OO in this plate and in Plate 

 XXIX is the midline of the body. In the anterior projection 

 it connects the anterior ends of the midlines of the sections. 

 In the posterior projection it connects the posterior ends 

 of these same midlines. 



The various organs are outlined in broken lines of suf- 

 ficiently dififerent character sc that each organ may be 

 traced without any difficulty. (These lines are explained 

 on the plates.
