zygomatico temporalis, 6 mm. right, 5 mm. at the left, and 

 3 foramina zygomatica. The tuberositas molaris is of 

 moderate size, and belongs mainly to the upper jaw ; the 

 tuberositas marginalis temporalis, especially the left, is very 

 strongly developed, and the bone very much bent inward 

 below. 



Skull No. 2. 



A senile, wholly toothless, probably male skull, without 

 lower jaw, of very moderate capacity (1,200 cub. cm.), but 

 strongly dolicho-orthocephalic (ratio of length and breadth 

 70-2, of length and height 73-2). 



It shows throughout a tendency to synosteosis ; the sagittal 

 suture is wholly obliterated — not a trace of it ; in the region 

 of the fontanelle a broad projection above the frontal bone, 

 as sign of early obliteration. The emissaria are present, but 

 very near together (distance 10 mm.), the right consider" 

 ably enlarged. The coronal suture obliterated in the lower 

 part to a considerable extent on the right ; on the left it is 

 perfectly simple, and in process of obliteration. At the right 

 the posterior part of the spheno frontalis is overgrown ; the 

 spheno parietalis on both sides indistinct. The lambdoidal 

 suture at its angle shows traces of obliteration. 



In the norma verticalis the skull is very long and narrow, 

 strongly arched in front, narrowed behind, with very pro- 

 minent lambdoidal angle, for the rest phsenozygomatic. The 

 tuberosities very broad and prominent, therefore somewhat 

 klinocephalic in form. At the right, on the parietal bone, 

 just behind the coronal suture, several flat exostoses. 



In the norma temporalis the skull appears rather long than 

 high. The middle of the parietal curve is flat, its 

 frontal division strongly arched, the posterior obliquely 

 gloping downward to the lambdoidal angle ; then, however, 

 much arched at the squama superioris. Eminences rising 

 even to the parietal prominences and the lambdoidal suture. 

 Squama temporalis flat. Alee depressed towards the centre, 

 especially the right one, which is very much narrowed
