'74 GEOEGE JOHN EOMANES 1878 



be much more important for the purposes of the book 

 than for those of the lecture. But, of course, I should 

 not ask to publish your work in my book, unless you 

 have no intention of publishing it yourself. I do not 

 know why you have kept it so long unpublished, and 

 your having offered me the manuscript for preparing 

 my lecture makes me think that you might not 

 object to lending it me for preparing my book. But 

 please understand that I only think this on the sup- 

 position that, from its unsuitable length, isolated 

 character, or other reason, you do not see your way 

 to publishing the chapter yourself. 



From C. Darwin, Esq. 



Down : June 19. 



My dear Eomanes, — You are quite welcome to 

 have my longer chapter on instinct. It was abstracted 

 for the Origin. I have never had time to work it up 

 in a state fit for publication, and it is so much more 

 interesting to observe than to write. It is very un- 

 likely that I should ever find time to prepare my 

 several long chapters for publication, as the material 

 collected since the publication of the Origin has been 

 so enormous. But I have sometimes thought that 

 when incapacitated for observing, I would look over 

 my manuscripts, and see whether any deserved publi- 

 cation. You are, therefore, heartily welcome to use 

 it, and should you desire to do so at any time, inform 

 me and it shall be sent. 



Yours very sir merely, 



Charles Dae win.
