eriod of transformation arrives, they are only two
lines from the orifice of the cells. As their position is constantly the
same, bent in an arc, those in the workers' and drones' cells are
perpendicular to the horizon, while those in the royal cells lie
horizontally. It might be thought, that the difference of position has
much influence on the increment of the different larvae; yet it has none.
By reversing combs containing common cells full of brood, I have put the
worms in a horizontal position; but they were not injured. I have also
turned the royal cells, so that the worms came into a horizontal
direction; however their increment was neither slower nor less perfect.

I have been much surprised at the mode of bees spinning their coccoons,
and I have witnessed many new and interesting facts. The worms both of
workers and males fabricate _complete_ coccoons in their cells; that
is, close at both ends, and surrounding the whole body. The royal larvae,
on the other hand, spin imperfect coccoons, open behind, and enveloping
only the head, thorax, and first ring of the abdomen. The discovery of
this difference, which at first may seem trifling, has given me extreme
pleasure, for it evidently demonstrates the admirable art with which
nature connects the various characteristics in the industry of bees.
You will remember, Sir, the evidence I gave you of the mutual aversion
of queens, of the combats in which they engage, and the animosity that
leads them to destroy one another. Of several royal nymphs in a hive,
the first transformed attacks the rest, and stings them to death. But
were these nymphs enveloped in a complete coccoon, she could not
accomplish it. Why? because the silk is of so close a texture, the sting
could not penetrate, or if it did, the barbs would be retained by the
meshes of the coccoon, and the queen, unable to retract it, would
become the victim of her own fury. Thus, that the queen might destroy
her rivals, it was necessary the last rings of the body should remain
uncovered, therefore the royal nymphs must only form imperfect coccoons.
You will observe, that the last rings alone should be exposed, for the
sting can penetrate no other part: the head and thorax are protected by
connected shelly plates which it cannot pierce.
Hitherto, philosophers have claimed our admiration of nature in her care
of preserving and multiplying the species. But from the facts I
