Quotation from: Manual of Surgery

If moist gangrene supervenes, amputation must be performed without
delay, and at a higher level.

#Gangrene from Heat, Chemical Agents, and Cold.#--Severe #burns# and
#scalds# may be followed by necrosis of tissue. So long as the parts are
kept absolutely dry--as, for example, by the picric acid method of
treatment--the grossly damaged portions of tissue undergo dry gangrene;
but when wet or oily dressings are applied and organisms gain access,
moist gangrene follows.
