Note. Since this last Chapter was written and the proof-sheets 

 revised, news has arrived of the failure of the last attempt to 

 transport salmon by means of new ova to Australia ; and although 

 we have not the precise facts of the experiment, yet I feel that the 

 failure hears out much that I have advanced in the foregoing 

 Chapter. The great point which it will be necessary to discover is, 

 whether any of the ova ever became so matured as for the eye to be 

 developed ; that we have yet to learn.
