dual, as we might express it, is a mechanical mixture of the features of 

 the parent types. He may have the face of a Tinneh, and the stature or 

 head of a Coast Indian, and vice versa. This important fact also tallies 

 exactly with Ammon's conclusions on the blonde and brunette population 

 of Baden, and confirms the views which KoUmann expressed in 1883. 

 (' Arcbiv fiii- Anthropologie,' xiii. 79, 179 ; xiv. 1.) The fact that these 

 conclusions have been arrived at independently on entirely independent 

 material seems to give them great strength. 



When we turn to a consideration of the Oregonian Tinneh, we shall 

 find the same phenomena, although apparently somewhat obscured. 

 Instead of two distinct maxima, we find here a great number of cases 

 distributed equally over a long interval. The next northern group 

 differs but little from the Tinneh, but their southern neighbours show 

 quite a marked contrast, particularly regarding their cephalic index. If 

 we assume the Oregonian Tinneh to be a mixture of the two, and keep 

 the fact in mind that no middle forms originate, the form of the curve 

 explains itself easily. In looking at the crosses between the two groups, 

 their distribution according to the maxima of the two component groups 

 is brought out most strikingly, notwithstanding the small number of 

 cases. 



In order to ascertain in how far these assumptions are justified, we 

 will subdivide the material in a different way. If the Oregonian Tinneh 

 contain a Californian element, we may assume that it is more prevalent 

 in the south than in the north. For this reason we will arrange the 

 material in the following groups : South of Rogue River, North of Rogue 

 River, and crosses between the two. We will compare preliminarily the 

 measurements from Northern Oregon with those of the group north of 

 Rogue River.

It appears that the two groups are quite homogeneous, so that we 

 may be allowed to combine them. Thus we obtain the following table : —
