Note 11 — Chapter XIII · THE SENSE OF SMELL

When, for the purpose of my studies, I require insects that dissect corpses, I expose a dead Mole in the sun, in a distant corner of the enclosure. As soon as the animal swells, distended by the gases of putrefaction, and the skin begins to turn green and the fur to fall from it, up come numbers of Silphæ11 and Dermestes,12 Necrophori13 and other Burying-beetles, of whom one would find not a single specimen in the garden, or even in the neighbourhood, without this bait.
