WORK ON 'MAN. 



1 864-1 870. 



[In the autobiographical chapter (Vol. I. p. 93), my father gives 

 the circumstances which led to his writing the ' Descent of 

 Man.' He states that his collection of facts, begun in 1837 or

 shows that in the period of ill-health and depression about 

 1864 he despaired of ever being able to do so :]

 must forgive me for not having sooner thanked you for your

 that I have hardly ever in my life been more struck by any 

 paper than that on ' Variation,' &c. &c, in the Reader. % I feel 

 sure that such papers will do more for the spreading of 



* On the three forms, &c, of % Reader, Ap. 16,1864. "On the 



Lythrum. Phenomena of Variation," &c.

March 1864. Linnean Society, Mar. 17, 1864.
