the occasional incident of the visit of some winged creature

July 25th. [1860] As I sit in my study, with the windows open, the occasional incident of the visit of some winged creature, wasp, hornet, or bee, entering out of the warm sunny atmosphere, soaring round the room in large sweeps, then buzzing against the glass, as not satisfied with the place, and desirous of getting out. Finally, the joyous, uprising curve with which, coming to the open part of the window, it emerges into the cheerful glow of the outside.
