"volition" to express the freedom of cell-mind, 

 and restricted the name ' ' free-will ' ' to the human 

 faculty of spontaneous action. 



In justice to myself I wish to state that nearly 

 the whole of the MS. for this edition was written 

 out before I had read Professor C. S. Minot's 

 admirable address on the " Biological Aspects of 

 Consciousness ' ' to the Pittsburgh meeting of the 

 " American Association for the Advancement of 

 Science," published in " Nature " for July 24th, 

 1902. (Vol. 66, p. 300.) It is remarkable that 

 Presidential addresses, both in America and in 

 Australia, should have been simultaneously on some- 

 what similar subjects, and that they should both 

 have independently arrived at the same conclusion ; 

 although Professor E . Haeckel says that fully nine- 

 tenths of the men of science do not believe in it.
