Meaning

The common-Mercury calcination account describes a white cloud emerging and a metal becoming brittle like coal. These are claimed visible effects used to characterize a transformation of bodily structure. Cloud does not name harmless water vapour here, and the account’s historical status matters. The edition’s note 38 flags the Mercury fumes rather than presenting the passage as an appropriate procedure to reproduce.
