human. The bony palate is beautifully domed, and the 

 typically human teeth are arranged round it in a horseshoe- 

 shaped row. The molar-premolar series of the two sides show 

 less approach to the ape-like parallelism than those even in 

 some existing races of men ; and the third molar, or wisdom 

 tooth, is considerably smaller than the other molars, thus 

 differing from that in all the lowest known races and resembling 

 that of the higher types of man. The front teeth are worn 

 down to stumps by the primitive edge-to-edge bite, but the 

 whole dentition has a very modern aspect from its partial 

 destruction by typical caries. No such decay has hitherto 

 been seen in the teeth of a prehistoric man. The only note- 

 worthy feature of the palate is its immense size, which is not 

 inferior to that of Neanderthal Man. The outside measure- 

 ment of the dentition across the second molars is 78 mm., and 

 the length from the socket of the median incisor to a line drawn 

 across the back of the third molars is 51 mm. This seems, 

 therefore, to be almost the largest known human palate, being 

 only slightly exceeded by the palate of the Wadjak Man 

 described by Dubois from Java. The lower jaw of Rhodesian 

 Man unfortunately remains unknown. 



If the great face with the brow-ridges were removed, the 

 brain-case would scarcely attract attention, except perhaps for 

 the unusual width of the flattened occipital surface for the 

 insertion of the neck-muscles. The thickness of the bone at 

 the accidentally broken edges in the lower part of the right 

 side is no greater than in ordinary European skulls ; but a 

 cast of the brain cavity proves that in most parts the bone is 

 as thick as in the average Australian skull. The total length 

 of the skull is about 210 mm., and its width at the parietal bosses 

 is about 145 mm. ; so that it is dolichocephalic, with a cephalic 

 index of 69. The capacity of the brain-cavity is about i ,280 c.c, 

 and according to Prof. Elliot Smith the brain must have been 

 of a very primitive type. 



There is a slight median ridge along the frontals, and the 

 skull rises to its maximum height just about the coronal suture. 

 This height (from the basion to the bregma) is 131 mm., the 

 same as in the Neanderthal skull from La Chapelle-aux- 

 Saints ; but the hinder occipital portion of the skull does not 

 show the bun-shaped expansion and depression which is so 

 characteristic of the skull just compared. The mastoid pro- 

 cesses, though small, are typically human. All the other parts 

 of the temporal bone are also essentially human, though the 

 downward extension of the tympanic at the back of the glenoid 

 cavity and the tightly-wedged petrous portion are a little 

 unusual. Most interesting of all, the rather large foramen 

 magnum occupies its ordinary human position, and if its plane
