number of observations is insufficient for applying this method. 

 As stated before, the distribution of measurements is such that 

 the parental types are more frequent than the average ; for this 

 reason the latter has no real biological significance. It must be

considered merely as a convenient index of the general distri- 

 bution. 



Among the eastern O jib was I was able to make a classifica- 

 tion into three groups: Indians, three-quarter bloods, and half 

 bloods. In this case (Fig. 6) it will be noticed that the influence 

 of the white admixture is very slight in the three-quarter bloods. 

 The maximum frequency of the breadth of face remains at 150 

 millimetres, and we observe that a small increase in frequency 

 takes place at 140 millimetres. 



From the breadth of face I turn to the consideration of the 

 height of face i. e., the distance from the chin to the suture 

 between the nasal bones and the frontal bone (Fig. 8). This 

 measurement is subject to considerable variations, on account of 

 the difficulty of determining the initial points of the measure- 

 ment with sufficient accuracy. This accounts for the irregularity

of the curves. It appears clearly that the face of the half blood 

 is shorter than that of the white. I am not able to say if this 

 phenomenon is due to a general shortening, or if the nose, the 

 jaw, or the teeth contribute most to this effect. The difference 

 between full blood and half blood is much smaller than in the 

 case of the breadth of face.
