Dear Sir

I am not sure whether your difficulty relates to a fly turning upside down in the air, or to its adhesion to the ceiling.1 If the former I can throw no light on the case, but do not see any special difficulty in the act.— With respect to adhesion, this is effected by viscid matter secreted by hairs on the pads or soles of the feet. You will find a short, but clear account of this structure in “The Anat. & Phys. of the Blow-Fly by B. T. Lowne.—1870”2

Dear Sir | yours faithfully | Ch. Darwin
