 the desirability of inheriting a good constitution and a high degree 

 of vigor and disease-resistance. It has been asserted that no measures 

 of hygiene and sanitation can take the place of such inheritance. It 

 is now desirable to ascertain the limits within which good inheritance 

 is effective, and this may be conveniently done by a study of the lives 

 of a group of people who inherited exceptionally strong physical con- 

 stitutions. 



The people referred to are taken from a collection of histories of 

 long life made by the Genealogical Record Office of Washington.
