The following (Table N) are perceutages placed iu the order of numerical importance of clas.ses 

 A + A' as tbey occur in various races. They are computed from figures given by Topinard*, Sala-

From the foregoing it would api)ear that the Saladuans come next to tlie Euroi)eans, in the 

 prevalence of a high form of the feature under discussion, and that they arc farther above the 

 Mongolians than they are below the Auvergnians. 



Position of septum. — In 1*8 .skulls in which the se2)tum narium is preserved we find that it is 

 straight in 4,t dellected to the left in ll,t and deflected U) the riglit iu 13.§ 



Anterior nasal spine. — We find cause for dissatisfaction iu applying Broca's instruction.s|| to 

 the description of this feature in the present series. We ofteu encounter a long, sharp ridge 

 extending from the extremity of the spine downwards to the alveolar point; this ridge renders 

 spines wliich are very prominent when viewed from above or below quite subdued when viewed 

 laterally, aecdrding to Broca's instructions. Thus, if it were not for the existence of such a ridge, 

 the spine <if skull II. 8 would belong to class 5 of Broca, whereas with this ridge it must be itlaced 

 in class 1 (see Plate 8) ; but, as we have no other system of description than that of Broca, we have 

 employed it here. 



Of 43 well-])reserved anterior nasal spines we have it of class No. 1 or the least salient, 2(1 of 

 class Xo. 2, 12 of class No. 3, 1 of class No. 4, and but 1 of class No. ."» or the most salient. See 

 Table xlvii. 



Nasal synostosis. — In seventeen of these skulls out of forty-two examined there is synostosis of 

 at least tlu- u[)per i)art of the internasal suture. The percentage then of nasal syno.stosis in some 

 degree is 40."). We ri'fer to the upper end of the suture more parti(!ularly, because the lower parts 

 of the bones are often broken away. A partial .synostosis of the suture at its lower end should 

 not be reckoned in with the others, as it may be the result of some traumatism. Skull H. 30 is 

 probably ;i case of this kind, as its nasal index is very low and its nasal bones deflected. It is 

 not counted in reckcming the jjcrcentage.
