on high authority,
not to be perfect even in that most perfect organ, the eye.

"That which we have discovered in the way of inexactness and imperfection in the optical machine and in the image on the retina, is as nothing in comparison with the incongruities which we have just come across in the domain of the sensations. One might say that nature has taken delight in accumulating contradictions in order to remove all foundation from the theory of a pre-existing harmony between the external and internal worlds."

If our reason leads
us to admire with enthusiasm a multitude of inimitable contrivances in nature, this same reason tells us, though we may easily err on both sides, that some other contrivances
are less perfect. Can we consider the sting of the wasp or of the
bee as perfect, which, when used against many attacking animals,
cannot be withdrawn, owing to the backward serratures, and so
inevitably causes the death of the insect by tearing out its viscera? |

If we look at the sting of the bee, as having originally
existed in a remote progenitor as a boring and serrated instrument, like that in so many members of the same great order, and which has
been modified but not perfected for its present purpose, with the poison originally adapted

intensified, we can perhaps understand
how it is that the use of the sting should so often cause the insect's
own death: for if on the whole the power of stinging be useful to the community,
it will fulfil
all the requirements of natural selection, though it may cause the death of some few members. If we admire the truly wonderful power of scent by which the males of many insects find their females, can we admire the production for this single purpose of thousands of drones, which are utterly useless to the community for any other end,
and which are ultimately slaughtered by their industrious and sterile sisters? It may be difficult, but we ought to admire the savage instinctive hatred of the queen-bee, which urges her
