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 

 sentence out of Naudin's paper in the * Revue Horticole,' 

 1852, p. 103, namely, that on his principle of Finalite. Can

 Flora Introduction. What was the date of publication : 

 December 1859, or January 1860? Please answer this. 



My preface will also do for the French edition, which, 1

 In 1838, ill-health compelled him to obtain leave of absence, and return
