My dear Sir.
I should be very much obliged if you would kindly tell me bywhat action you think the curious resemblance of the Bee, Spider& Fly Ophrys to the several insects has been produced—f1 It is I thinkfar too marked & striking to be accidental!
I have also great difficulty in seeing by what possible action of naturalor sexual selection the beauty of bivalves can have been produced and Ishould be grateful for any hint from you on the subject which (unlessyou tell me I may quote) I shall consider confidentialf2
I feel sure you will kindly excuse my thus troubling you & remain
My dear Sir | Always Your’s very truly | St G Mivart
