as below, the bridge very prominent, bent in at the middle, 

 almost aquiline ; index 46, therefore leptorrhine. The sutura 

 naso frontalis fits convexly above into the nasal process of 

 the frontal bone. Spina anterior and inferior well developed 

 and prominent ; crista and septum very thick. On the cheek- 

 bone either side a short indication of a posterior fissure, 

 which, however, lies very high ; on both sides three small 

 foramina zygomatica. Canine fossw are little depressed, but, 

 on the other hand, run from the immensely broad foramen 

 infraorbitale on either side to the alveolar process, which is 

 more strongly developed on the left, making a very deep 

 fissure. The alveolar process is entirely toothless, but there 

 are still single open alveoli, especially at the left in the region 

 of the bicuspids and first molars ; most of the alveoli, espe- 

 cially those of the incisors, are entirely obliterated, and the 

 process has disappeared, so that the shape of the very much 

 shrunken palate is uncertain. Here also the position of the 

 transverse suture is remarkable, because it is pushed so far to 

 the front as to be at a distance of 14 mm. from the posterior 

 edge. The spina nasalis posterior is wholly wanting; a short 

 bifid projection larger on the left than on the right. 



Skull No. 3. 



A child's skull, perhaps female, with the not yet exchanged 

 milk teeth. The outer upper cutting teeth are still enclosed 

 in their cavities. The sutura incisora of the palate very plain. 

 The bicuspids and first molars developed, and very large. 

 The first bicuspids with three fangs, two outer and one inner, 

 the right one, moreover, with an exosteosis of enamel. The 

 alveoli of the second molars are open very wide, and empty, 

 but the teeth, to be sure, had not yet erupted. The openings 

 of the alveoli of the wisdom teeth still lie very deeply, and 

 far back. The synchondrosis spheno occipitalis very widely 

 open. To the right, at the squama occipitalis, is a sutura 

 mendosa 24 mm. long, in the direction of the sutura trans- 

 versa ; at the right only a slight indication of one. 



Notwithstanding youth, this skull is larger than the two
