Note 755 — LETTER XIII.
Reading edition
The nests of this animal which I saw at Fontainebleau (in the pit producing the fossil named after that place) were scarcely half the dimensions here given, but they might probably be younger insects. I kept one in a box of sand several days, in which it regularly formed its pit, whenever obliterated by shaking. The bottom of the box unfortunately came out as I was upon my return to England, and the animal was killed.
