The two measurements combined sliow that the Indian face is 

 considerably larger than the face of the half blood, while the 

 latter is in turn larger than the face of the white. As the head 

 measurements of the tribes which have contributed to these sta- 

 tistics prove that there is no appreciable difference between these 

 races regarding the size of the head, we are led to the conclusion 

 that the Indian face is also relatively larger than that of the half 

 blood and of the white. 



Another characteristic difference between Indians and half 

 bloods will be found by comparing the breadth of nose of both 

 races. It is well known that the nostril of the Indian is round, 

 and that it is bordered by thick alse, while the nostril of the 

 white is elongated and has fine alee. Unfortunately, there are 

 no measurements of the nose of the white available, but a com- 

 parison of the transversal breadths of the nose of Indian and 

 half blood (Fig. 9) makes it clear at once that intermixture has 

 the effect of making the nostril narrower and the alae thinner.

thus producing a much narrower nose. It appears at once that 

 the nose of the half-blood man is not wider than that of the 

 full-blood woman. The three-quarter bloods of the Ojibwas (Fig. 

 10) are found to take an intermediate position between full bloods 

 and half bloods. 



We will finally consider the effect of intermixture upon the 

 length of head from the point between the eyebrows (the gla- 

 bella) to the occiput among a tribe with a head that is shorter 

 than that of the American white. The Ojibwa has a head which 

 measures about 191 millimetres, while that of the white meas- 

 ures about 195 millimetres. A comparison of the three classes 

 (Fig. 11) shows a gradual increase in length from the full blood, 

 through the three-quarter blood, to the half blood. 



We find, therefore, that the laws of heredity in the forms of 

 the head and face are uniform, in so far as intermediate forms 

 are produced. I presume, however, that in all these cases the 

 middle forms are not found as frequently as forms resembling the 

 two parental types.
