Vili FOOT-NOTES TO EVOLUTION. 
Leland Stanford Jr. University. The essay of Professor 
Conklin was read before the American Philosophical So- 
ciety. The others are here presented for the first time. 
I may add that the present volume is not intended 
as a text-book in Evolution, although most phases of 
organic development are in one way or another touched 
upon, some of them, however, mgst briefly. The treat- 
ment of different topics is necessarily unequal. The 
time is long past when any one man can master what is 
known in any science, least of all the universal science 
of life. In the supplementary essays I have asked my 
scientific friends to do for this volume certain work 
which I could not do except by the unsatisfactory 
method of compilation.
