 its variations. Observe how Wales and Cornwall are set apart from 

 all the rest of the island. Were the map more extensive, we should

 Briton types, characterized by an equal infrequency of suicide. 

 Most remarkable of all is the little light-colored area, just north of

 tons entered England from two sides, avoiding London and the im- 

 penetrable fen district, and thereby passed over this region, leaving 

 it notably brunette in physical type to this day. Here, again, in 

 nearly every detail of our map would seem to be a corroboration of 

 Morselli's law. For suicide diminishes in direct proportion to the 

 absence of Teutonic intermixture. 



Divorce and suicide, which we have just discussed, will serve 

 as examples of the mode of proof adopted for tracing a number of 

 other social phenomena to an ethnic origin. Thus Lapouge at- 

 tributes the notorious depopulation of large areas in France to the 

 sterility incident upon intermixture between the several racial
