My dear Innes

The wasp’s nest has arrived safe, except part of the outer walls, & was wonderfully well packed.² The cells are not half such disagreeable objects, as I expected to see them; as the outer walls, when not in contact with any other cell, are distinctly rounded or curved; & the extreme bases or bottoms of the cells are also rounded. If a queen wasp were to make a single cell in the shape of a hexagon, the fact w^d. have been an odious one in my eyes.³ I believe that she builds up several cells at the same time & makes straight walls between the adjoining cells;; & these intersecting plates between 6 surrounding cylinders produces the hexagon.— But the subject has gone out of my head, & I cannot spare time to force it into my old worn-out brains.

Very many thanks for your most kind letter | Ever yours sincerely | Ch. Darwin
