244 GEOKGE JOHN ROMANES isss- 



never have been published at all; and therefore have 

 come here to-day in order to look through the back 

 numbers of ' Nature,' with a view to republishing as a 

 small book the various things that I have contributed 

 during the past twenty years. Thus it is I find that 

 the explanation which I gave to Herbert Spencer re 

 Panmixia and his articles on the ' Factors of Organic 

 Evolution,' appeared in August 25, 1887, and showed 

 that his whole argument was in the air. 



I have also read my own article on Panmixia, 

 written about two months ago, and published last 

 week. The result is to satisfy me that your ' intelli- 

 gent ' friends must have had minds which do not 

 belong to the a priori order i.e. are incapable of 

 perceiving other than the most familiar relations. 

 Such minds may do admirable work in other direc- 

 tions, but not in that of estimating the value of 

 Darwinian speculations. A few years ago they 

 would have thought the cessation of selection a very 

 unimportant principle, and one which could not 

 possibly sustain any such large question as that of 

 the transmissibility of acquired character. And a 

 few years hence they will wonder why they raised 

 such an ado over the no less obvious principle of 

 physiological selection. 



Yours very truly,
