Figure 6. Early Drawings of the Brain of the Dolphin and 

 of the Porpoise by Tiedemann. 



These drawings were reproduced by H. G. L. Reichenbach in his 

 Anatomia Mammalium in 1845. These are more accurate renditions and 

 show the lateral expansion of these fine brains. (Courtesy of the Library
