 until finally the two eyes were found on the same side. So 

 fruitful variation and evolution is in the line set and main- 

 tained by the individual accommodations, quite in the 

 absence of determinate variation. 



§ 2. Selections and Selection 



3. Without going into the question, it may yet be 

 said that the position taken by Professor Poulton in the 

 matter of the relation of natural to organic selection — 

 that plasticity is itself due to natural selection — is, as he 

 says, that advocated here ; but I have given natural 

 selection still further emphasis by making the 'functional

 tion broadly understood. I have recently drawn up a 

 table showing the various sorts of * selection * under the 

 distinction of 'means* and immediate 'result,' finding

 etc., p. 732) to describe Roux' 'Struggle of the parts,' 

 akin to functional selection. Seeing that Weismann's

 in the work, Social and Ethical Interpretations^ Index and Appendix B, where 

 acknowledgment is made of suggestions from Professor Lli)yd Morgan. Ap-

 the table is now printed here.
