Signs of the four kinds of burns

A touched burn is badly discoloured and very hot; an even burn is black like sesame, hot and not deep; a bad burn raises many blisters, causes fierce burning pain and settles slowly; an over-burn brings fainting, great thirst, heaviness of joints, wasting of limbs, hanging flesh, pain in vessels, ligaments and bones, later worms in the wound, slow healing and lasting discolouration.
