1864. 



[In my father's diary for 1864 is the entry, " 111 all January, 

 February, March." About the middle of April (seven months 

 after the beginning of the illness in the previous autumn) his 

 health took a turn for the better. As soon as he was able

 than one or one and a half hours' work. It is a good deal 

 harder than writing about my dear climbing plants."

 present to receive it, but this the state of my father's health 

 prevented. He wrote to Mr. Fox on this subject : 



" I was glad to see your hand-writing. The Copley, 

 being open to all sciences and all the world, is reckoned a 

 great honour ; but excepting from several kind letters, such 

 things make little difference to me. It shows, however, that
