Mr. Wallace and Reichenbach's Odyle

Abstract

I HAVE to request your insertion of a post-card I have this morning received, for two reasons; first, because, as it is anonymous, and as the writer of it is obviously a reader of NATURE, no other way is open to me for replying to it except that which your columns may afford; and secondly, because it is a very curious example of the misconceptions into which men are apt to fall who allow themselves to become “possessed” by “dominant ideas”.
