THE HUMAN SPECIES. 157 



of forehead, there occur only indications of morbid' 

 development, and ideal exaggerated profiles of Greek 

 divinities, whose overhanging brows, and deep seated 

 eyes, produce the effect of a calm shadowy frown, which 

 we learn to view as an attribute of majesty and con- 

 scious power. Much, however, and indeed the essen- 

 tial, in all mental constitution, must depend upon the 

 proportions of the cerebral structure being in sufficient 

 harmony for their rational operation ; and this condi- 

 tion is found preserved, without material injury to 

 ratiocination, where both the anterior and posterior 

 portions of the brain are distorted by artificial pressure 

 in infancy, or where the volume is small, by the 

 retreating low angle of the forehead ; whether or not 

 the case applies to a whole race, or to an occasional 

 individual among bearded tribes. 



It appears, that individual interunions between the 

 typical races, not only tend to the superior development 

 of form and capacity in the offspring, but that the 

 same tendency continues to operate between different 

 tribes; the constant crossing of Celtic with Teutonic* 

 blood, upon a Perso-Arabian basis, being perhaps a 

 principal cause of the early progressive civilization of 

 Southern and Western Europe; and the stationary 



statesmen and warriors, probably all as ambitious men. It 

 were to be wished that portrait painters paid more minute 

 attention to this object we mean, placing the aperture of 

 the ear in relation to the nostril. It is important to them 

 for the sake of truth, and to the physiologist for the same 

 reason ; since, without accuracy, he cannot draw fair con- 

 clusions from painted human likenesses.
