^ This list of literature makes no pretension of citing other than a few 

 of the most important books and papers on inbreeding published in pre- 

 Mendelian days. Those interested in the subject from the standpoint of 

 marriages of near kin can obtain access to the literature by following up the 

 citations of Huth and of Westermarck. The real development of the subject 

 has come from the investigations on heredity completed since the year 1900. 

 Since it is impracticable and unnecessary to citel all the genetic work of 

 this period, only those titles which are in some way directly connected with 

 the subjects discussed, have been given.
