APPENDIX. 



The scope of the biographical inquiry and the evidence from 

 which the tables have been constructed are shown in the following 

 list. The birth-ranks as far as known are appended to each name 

 in brackets immediately following the dates of birth and death. 

 The absence of a birth-rank does not necessarily mean that the 

 rank may not be found, but simply that I have not been able to find 

 it from the facilities at hand or without an amount of research 

 which I was unwilling to give the matter at this time. 



The amount of effort given to finding dates has varied with the 

 individual to whom they related. For the more eminent of these 

 men every available source was examined before search was aban- 

 doned ; for the less eminent I have been content to examine those 

 sources which were most convenient. The sources from which I 

 have obtained these dates have been biographical dictionaries, 

 American, French, German, and Spanish Encvclopaedias, and in- 

 dividual biographies. In a number of cases I have found that the 

 dates given by one authority do not correspond with those given 

 by another. In such cases I have sometimes adopted the date 

 which appeared to have the best authority, and in other cases I 

 have used the date given by the last found authority on the as- 

 sumption that I may have made a mistake in copying the first date. 

 Such cases are, however, comparatively rare, and usually do not 

 involve a difference of more than one, two or three years. While 

 the proper ranking of any individual should involve the birth-ranks
