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. Cornelius 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.
