Burns are cured by applying ashes of calcined sea-crabs or river-crabs with oil: fish-glue, too, and calcined frogs are used as an application for scalds produced by boiling water. The same treatment also restores the hair, provided the ashes are those of river-crabs: it is generally thought, too, that the preparation should be applied with wax and bears' grease. Ashes, too, of burnt beaver-skin are very useful for these purposes. Live frogs act as a check upon crysipelas, the belly side being applied to the part affected: it is recommended, too, to attach them lengthwise by the hinder legs, so as to render them more beneficial by reason of their increased respiration.[1] Heads, too, of salted siluri[2] are reduced to ashes and applied with vinegar.

Prurigo and itch-scab, not only in man but in quadrupeds as well, are most efficaciously treated with the liver of the pastinaca[3] boiled in oil.
