To John Obadiah Westwood 15 August [1861]
Summary
As a general rule CD thinks it best to deposit specimens in the British Museum, and "bitterly regrets" he did not send all his specimens there. Nevertheless he agrees to sending his crustaceans to the Oxford Museum.
CD is at work on Orchids. He would be greatly obliged if JOW could send him specimens of pollen-masses attached to head or base of proboscis of moths.
Asks for reference to Morren’s paper that JOW mentioned before [see 2862].

To J. O. Westwood 4 September [1861]
Summary
Is certain he never had Morren’s paper from JOW or heard of it before JOW’s note; will write to Gardeners’ Chronicle about it [see 3252].
Thanks for the two Sphinx moths; unfortunately the pollen-masses do not belong to orchids but to Asclepias.
Asks whether R. B. Todd’s Cyclopedia of Anatomy and Physiology [1835–59] has an article on fertilisation of orchids.
