From William Ogle   [23–4 September 1875]1

Oxford and Cambridge Club

the passage in which A. states this, I am inclined, though not certain, to believe his statement to be correct. Supposing bees or other insects to have such a habit, its utility is of course apparent, since your works on fertilisation of flowers.2 I should very much like to know whether bees or other insects do so limit themselves, and whether the fact has been observed either by yourself or by any other Naturalist.

Of what advantage would such a habit be to the insects themselves?

I trust you have recovered from the fatigue of your last work; which I read with great delight; though unfortunately with the help of very unhealthy specimens of Drosera, with which London air did not seem to agree.3

Believe me | Yrs. very sincerely | W. Ogle.

P.S. | In Latin Renuo, and Annuo answer to ἀνανεύειν and κατανεύειν.4

End of letter: ‘Dr Ogle says that Aristotle observes that Bees on any single journey from the hive limit their visits to a single kind of flower   The bee for works for a time, that is as long as it can find flowers of the same sp. on the principle that an if [above del ‘man can engine’] a man [‘by habit can make’ del] had to make 6 [above del ‘several’] engines, he wd complete the work quicker, if he made [‘[illeg] 6’ del] 6 of the wheels of each kind one after the other. habit above consists of an [above del ‘are complex’] apparatus consisting of several parts’ ink
The date is established by the relationship between this letter and the letters to William Ogle, 22 September 1875 and 25 September 1875.
In this incomplete passage, Ogle was evidently writing about bees’ habit of returning repeatedly to flowers of the same species; see CD’s annotation to this letter, and CD’s letter to Ogle of 25 September 1875. Aristotle made his observation in his History of animals 624b. CD mentioned Aristotle’s observation in Cross and self fertilisation, pp. 415–16.
CD discussed Drosera (sundew) in the first part of his Insectivorous plants.
