My dear Hooker, — I have resolved to publish a little 



sketch of the progress of opinion on the change of species. 



Will you or Mrs. Hooker do me the favour to copy one

P.S. — I shall end by just alluding to your Australian 

 Flora Introduction. What was the date of publication : 

 December 1859, or January i860? Please answer this. 



My preface will also do for the French edition, which, /
