Dr. Abram Cox has suggested, that the size of the convolutions which con- 

 stitute the organs of self-esteem, love of approbation, concentrativeness, adhesive- 

 ness, and philoprogenitiveness, may be estimated by their projection beyond a base 

 formed by a plane passing through the centres of the two organs of cautiousness 

 and the spinous process of the occipital bone. He was led to this conclusion by 

 a minute examination of a great number of the skulls in the collection of the 

 Phrenological Society. A section of this plane is represented by the lines C, D, 

 in Figs. 1 and 2. 



To determine the size of the convolutions lying in the lateral regions of the 

 head, Dr. Cox proposes to imagine two vertical planes passing through the organs 

 of causality in each hemisphere, and directly backwards, till each meets the outer 

 border of the point of insertion of the trapezius muscle at the back of the neck. 

 The more the lateral convolutions project beyond these planes, the larger do the 

 organs in the sides of the head appear to be — namely, combativeness, destructive- 

 ness, secretiveness, cautiousness, acquisitiveness, and constructiveness; also, to some 

 extent, tune, ideality, wit, and number.

Fig. 3 represents a horizontal section of the skull of a Cingalese, the lines B 

 T being sections of the planes above described. Fig. 4 represents the same section 

 of the skull of Gottfried, the female poisoner already referred to. The lateral 

 expansion of the head beyond the lines B T in Fig. 4, forms a striking contrast 

 with the size of the same regions in Fig. 3. The Cingalese are a tribe in Ceylon, 

 and in disposition are remarkably mild and pacific. 



Dr. Cox suggests farther, that the size of the convolutions lying at the base 

 of the brain, may be estimated by their projection below a plane passing through 

 the superciliary ridges and the occipital spine, (D E, Fig. 1, and D, Fig. £,) and 

 by observing the distance at which the opening of the ear, the mastoid process, 

 and other points of the base of the skull, lie below that plane.
