 threads of this connection between remotely afhliated nations are sometimes 

 recovered in the most unexpected manner. These tables, therefore, as but the 

 commencement of the work if this new instrument in ethnology invite the test 

 of criticism. The remaining nations of the earth can be reached and their systems 

 procured, should it seem to be desirable; and it maybe found that this is the most 

 simple as well as compendious method for the classification of nations upon the 

 basis of affinity of blood.' 



' In the appendix to this volume will be found a schedule of questions adapted to this work. 

 Any person interested in the furtherance of this object, who will procure the system of any nation 

 not represented in the tables, or correct or complete any deficient schedule therein, will render a 

 special service to the author. The schedule may be sent to the Smithsonian Institution, at Wash- 

 ington; and when published full credit will be given to the person furnishing the same.
