26 September | 1861
My dear Mr Darwin
I have succeeded in finding the reference to Morren’s paper1 which appeared in the Horticulteur Belge about 1835 & of which an abstract was given in the Trans. Ent. Soc. 1. Proc. p xliv & xlix2 It is entitled “On the Agency of insects in causing Sterility in flowers by the removal of the masculine organs observed among the Asclepiadeæ.” The insects observed were our common white butterflies the tarsi of which were loaded with the pollen masses of the plants in question—not Orchideæ.3
If you could conveniently let my little box be left either at Van Voorst’s Paternoster Row—or the British Museum I should get it in time4
Yours very truly | J. O. Westwood
