Letter 614 



[CHAP. X 



To John Lubbock (Lord Avebury). 



Cliff Cottage, Bournemouth, Wednesday, Sept. 3rd [1862]. 



I beg a million pardons. Abuse me to any degree, but for- 

 give me : it is all an illusion l (but almost excusable) about the 

 bees. I do so hope that you have not wasted any time from my 

 stupid blunder. I hate myself, I hate clover, and I hate bees.

 Letter 615 To J. D. Hooker. 



Cliff Cottage, Bournemouth, Sept. nth, 1862. 



You once told me that Cruciferous flowers were anomalous 

 in alternation of parts, and had given rise to some theory of 

 dedoublement. 



1 H. Miiller, Fertilisation of Flower s^ p. 186, describes hive-bees visiting 

 Trifoliuiu pratense for the sake of the pollen. Darwin may perhaps have 

 supposed that these were the variety of bees whose proboscis was long 

 enough to reach the nectar. In Cross and Self Fertilisation, p. 361, Darwin 

 describes hive-bees apparently searching for a secretion on the calyx. In the 

 same passage in Cross and Self Fertilisation he quotes M tiller as stating 

 that hive-bees obtain nectar from red clover by breaking apart the petals. 

 This seems to us a misinterpretation of the Befruchtung der B lumen, p. 224.
