Physiological Selection and the Origin of Species

Abstract

As I was unable to be present at the Linnean Society when Mr. Romanes read his paper on the above subject, I may take the opportunity furnished by the publication of the abstract in these columns to put forward certain views which I have long held with reference to the points raised by the author. I may remark that I am writing under the disadvantage of distance from notes or books of reference, and that I have not yet seen the complete paper. Moreover, my work of late years has run off biological tracks, and I can but regret that my remarks must, under the present circumstances, be of a more or less general character; but at any rate they may be of use as a contribution to the discussion which Mr. Romanes' carefully considered paper well merits at the hands of biologists.
