process strongly prognathous, but only 18 mm. long, with 

 very large alveoli. Palate deep and broad behind, with slightly 

 horse-shoe shape. Alveolar ridge 90, therefore brachy- 

 staphyline. Horizontal plate of the palate bone more promi- 

 nent anteriorly in the middle ; short spina nasalis 

 posterior. 



Skull No. 2. 



A senile male skull without lower jaw, of small, but yet, 

 beside the others, of relatively larger capacity (1,260 cub. 

 cm.), still dolichocephalic (74*8), and of moderate height 

 (length to height index 73*7) ; very marked places of attach- 

 ment for the muscles. Occipital protuberance large, almost 

 hook-shaped. The nasal prominence of the frontal bone 

 broad, protruding greatly, and with jagged traces of the 

 lower part of the frontal suture. The right malar bone, with 

 the contiguous part of the upper maxilla and zygomatic arch 

 wanting ; right side of the skull slightly eroded by decay. 



In the norma verticalis the skull seems a pretty regular and 

 broad oval, with its greatest extent in the region of the parietal 

 eminences, and slightly phaenozygmatic. The middle part of 

 the sagittal suture rather simple, the left foramen wanting, 

 the right lying very near to the suture. The lower side 

 divisions of the coronal and of the sutara spheno frontalis 

 obliterated ; beginning of synosteosis of the spheno frontalis. 



In the norma temporalis we see very high planes, which 

 reach above the tubera and up to the lambdoidal suture, 

 ending posteriorly on the left in a thick sclerotic surface 

 whose edge overlies the lambdoidal suture ; ala broad and 

 indistinct on the right, 26 mm. broad on the left. 



In the norma occipitalis the section is seemingly nearly pen- 

 tangular, broad, moderately high, with a somewhat flattened 

 roof. The squama are large, especially broad ; the lambdoidal 

 angle about 160 degrees. The protuberance well developed, 

 as also the linea semicircularis superior ; in place of the linea 

 suprema, however, a flat ridge. Fades muscularis strongly 

 marked ; cerebellar archings only slightly developed, middle
