usage, all being much worn, and the enamel having disap- 

 peared from the crowns of all, excepting the dentes sapientiae. 

 The incisors above and below, were so far worn, as to expose 

 the pulp cavity, and the canines of the lower jaw so far 

 truncated, as not to project above the contiguous incisors ; 

 upper canines also worn to nearly the same extent. An- 

 other very striking peculiarity exists, and which has been dis- 

 tinctly figured by Professor Owen as existing in the Ourang 

 Outang,* viz. that of the central incisors of both jaws being 

 more worn thtin the lateral ones, so that when the jaws are 

 closed, an oval space is left between them. 



Two anterior condyloid foramina exist on one side, and 

 but one foramen on the other. 



No. II. This cranium presented the same general characters 

 as the preceding, except that the coronal belt or inter-parietal 

 space was narrowest at its posterior portion near the occiput. 

 The obliteration of the sutures was even more extensive than 

 in the preceding, the lambdoidal only remaining open for the 

 distance of a quarter of an inch — with this exception all the 

 bones of the cranium were coossified into one inseperable 

 mass. 



Three distinct infra-orbitar foramina existed in this specimen, 

 two of nearly equal size situated in the same horizontal line, 

 instead of being one above the other, as in the preceding, and 

 a third much smaller about half way between them and the 

 lower margin of the orbit. 



Foramen incisivum single, and two anterior condyloid 

 foramina on each side. The lower jaw was wanting, and the 

 incisors and canines had disappeared from the upper. The 

 molars and bicuspeds as in No. I. presented a continuous 

 series, and the enamel was worn through in many places on 

 the surfaces of the crowns. 



From the above observations, it will be obvious that the 

 crania were those of aged individuals, and that in them an 

 obliteration of the sutures takes place as in the Ourang of
