THE facts of regeneration are amongst the most 

 significant in relation to the vitalistic contro- 

 versy, and a further chapter must be devoted 

 to considering them in conjunction with some 

 further observations in experimental embryo-

 the theories dealt with in this chapter will be found in 

 perhaps their easiest form. (3) The History and Theory of 

 Vitalism; same publisher and date.
