The internal capacity of this skull is 95.5 cubic inches ; the capacity of the 

 coronal region f21.^5 cubic inches; facial angle, 87 . 



On comparing these measurements with those of the American skulls as 

 exhibited in Dr. Morton's tables, the diflferences will be seen: or by comparing 

 the dimensions of this Swiss skull as they appear to the eye in the plate, with 

 those of the other skulls delineated in this work, all being drawn as large as 

 nature, their relative proportions will become apparent. 



As, however, different parts of the brain manifest different mental faculties, 

 the second object in studying national crania is to judge of the size of the 

 different parts of the brain in relation to each other. This is indispensable to a 

 correct elucidation of mental character as indicated by the brain ; but the limits 

 to which I am confined prevent me from entering into minute detail. I, there- 

 fore, confine myself to a few directions for estimating the size of each of the three 

 great regions of the brain — that which is the seat of the intellectual faculties; that 

 which is the seat of the moral and religious sentiments ; and that which is the 

 seat of the animal propensities, and of the sentiments common to man and the 

 lower animals. 



1st. The anterior lobe of the brain is the seat chiefly of the intellectual 

 powers. The lower ridge, and the middle perpendicular portion, manifest the 

 faculties which observe objects that exist, their qualities, actions, and physical 

 relations. The upper anterior ridge manifests the powers which compare, reflect, 

 estimate causes, and draw inferences. The superior horizontal portion of the 

 anterior lobe manifests some of the moral sentiments. 



The anterior lobe rests on the super-orbitar plates, and these plates indicate 

 its breadth from side to side, and its length from front to back. The breadth can 

 be estimated by means of callipers applied to the exterior of the skull, at the 

 point where the super-orbitar plate reaches each side. A, Plate LXXI. The length 

 of the super-orbitar plate, and of the anterior lobe, from front to back, may be 

 judged of, not with mathematical accuracy, but to a degree closely approximating 

 to truth, by measuring the distance to which the skull extends forward from the 

 point A to B on the superciliary ridge. The point A is located in the middle
