My dear W.

Very many thanks for your excellent observations. I will send the Fly to B. Museum & get it named—²

If you are not wearied out, I certainly sh^d be very glad if you c^d. pay another visit. I still think some larger insect must visit the plant; probably wasps.—

I feel sure about the elasticity of Hinge in the specimens which I examined.—³ May not the dry Weather have acted injuriously on the plant?—

When you come here, I must ask you about one point— viz whether the fly with pollen-masses attached to it, crawled out over the distal & flexible part of the labellum but without depressing this part, or crawled out (as I supposed) nearer the centre of the flower, ie between the 2 upper petals.

I am ashamed that you sh^d. have had to watch so long.—

Very many thanks, my dear old fellow, | In Haste for Post | yours affect. | C. Darwin.
