viii PREFACE 



The book owes much to the interest of friends who 

 have lent letters for publication, and whom I have 

 the pleasure of thanking in behalf of Radcliffe Col- 

 lege. Material kindly given by Mrs. CorneHus Con- 

 way Felton is at her request specified : the letters on 

 pages 180 and 276 and the manuscript from which 

 selections appear on pages 277 to 279. Warm thanks 

 are also due to friends and various members of Mrs. 

 Agassiz's family for advice and suggestions, and es- 

 pecially to Mrs. Henry L. Higginson and Mrs. Rob- 

 ert Shaw Russell for material and information gen- 

 erously supplied. The Commemoration Addresses 

 in Chapter XV are republished from the Harvard 

 Graduates' Magazine for March, 1908, by the cour- 

 tesy of its editor.
