and the bony meatus of the ear corresponds with that of all other 

 Caucasian nations. 



Two other heads present some mixture of Negro lineage with the 

 Egyptian, which is expressed in the conformation and expression 

 of the facial bones, more particularly as seen in the greater breadth 

 and flatness of the face, and a stronger development of the upper 

 maxilla. 



Of these thirteen crania, eleven are adult, of which the largest 

 has an internal capacity of 93 cubic inches, and the smallest 76, 

 giving a mean of 86 cubic inches for the size of the brain. This 

 measurement exceeds, by only three cubic inches, the average de- 

 rived from the entire series of Egyptian heads in my Crania 

 iEgyptiaca. 



The facial angle of the adult heads gives a mean of 82°, the 

 largest rising as high as 86°, and the smallest being 78°. Two 

 other heads are those of children, in whom the Egyptian conforma- 

 tion is perfect, and these give, respectively, the remarkably large 

 facial angle of 89° and 91°. The mean adult angle is greater than 

 that given by the large series measured in the Crania iEgyptiaca. 

 Is this owing to the fact, that the heads now under consideration 

 belonged to persons of distinction, and probably, therefore, of edu- 

 cation and refinement ? 



These crania, as already observed, are long and narrow, and 

 receding in front ; but posteriorly, in the parietal regions they be- 

 come much broader ; the whole occiput is very full, and remarkably 

 projecting ; the sides of the cranium are rather flat, and the coronal 

 region long and depressed. 



2. The Negroid head, as I have elsewhere explained, is a mix- 

 ture of the Caucasian and Negro form in which the latter predomi- 

 nates. Such is the case in the present instance, as even a partially 

 practised eye can readily discover. This head strongly resem- 

 bles those of two modern Copts in my possession. It gives 81 cubic 

 inches for the size of the brain, and a facial angle of 80. It is re- 

 markable for deep depressions on the lateral surfaces of the parietal 

 bones, apparently caused by the action of the posterior portions of 

 a powerful occipito-frontalis muscle. Among six hundred skulls in 

 my collection, but two present this development in an equal degree ; 

 one of these is an Egyptian, the other a Hindoo head.
