[Footnote: M. RAVAISSON'S reading varies from mine in the following passages:
1.opero allor [?] bo [alloro?] = "ou bien de [laurier]."
- fregalo bene con un panno. He reads pane for panno and renders it. "Frotte le bien avec un pain de facon [jusqu'a ce] qu'il" etc.
- colla stecca po laua. He reads "polacca" = "avec le couteau de bois [?] polonais [?]."]
