Mortoii's Crania Americaria. 



We can afford space only to notice Mr. Combe's illustration of 

 the location of the great divisions of the faculties in the different

 results intelligible to the reader. 



Swiss, Fig. 3. 



All the figures are drawn to the same scale. 



In this figure (Fig. 3,) a line drawn from the point A trans- 

 versely across the skull, to the same point on the opposite 

 side, would coincide with the posterior margin of the super- 

 orbitary plate : the anterior lobe rests on that plate. The line 

 A B, denotes the length of the anterior lobe from back to front, 

 or the portion of brain lying between A A and B B in figures 

 1 and 2. A in figure 3, "is located in the middle space be- 

 tween the edge of the suture of the frontal bone and the edge of 

 the squamous suture of the temporal bone, where these approach 

 nearest to each other, on the plane of the super-ciliary ridge." 

 We have examined a Peruvian skull of the Inca race, a skull of 

 a fiat-headed Indian, an Indian skull found near Boston, and com- 

 pared them with several skulls of the Anglo-Saxon race, and ob-

 in the former, and that it corresponds with the length of the ante-
