296 STUDY OF BRAINS OF SIX EMINENT SCIENTISTS AND SCHOLARS. 



in the temporal fossa. The squama is reduced. The sutures in general show a fine 

 serration. The appended measurements give further details which I will not recount 

 here. The following characters of the skull may, however, be mentioned. 



The skull is nearly mesaticephalic ; there is facial orthognathism ; the mandible 

 is delicate ; the nasal spine is pronounced. The nasion depression is quite marked ; 

 the malars are not very prominent ; the zygorase are quite delicate. The glabella is 

 moderate ; the supraorbital I'idges are slight and most marked in their mesal portions, 

 near the glabella. There is no pronounced sagittal elevation. 



On the base of the skull may lie noted : the styloids as well as the vaginal and 

 spinous processes are well preserved ; the styloids are strong and 2.5 cm. in length. 

 The right jugular foramen is larger than that on the left side. The petrous portions 

 are quite sunken within the surrounding parts as viewed ventrally. The basi-occipital 

 and sphenoid are fused. 



The internal capacity of the cranium, measured with dry mustard seed, is 1645 

 c.c. The weight of the skull minus mandible is G70 grams; the weight of the man- 

 dible is 72 grams.
