PUTREFACTION OR DECOMPOSITION 135 Fig. 35.—Decomposed body of a boy, 8 years old. The cuticle has peeled off at places. Internal Phenomena.—The changes of discoloration similar to those described in the external phenomena of putrefaction are observed in the various visceral organs, such as the liver, spleen and kidneys, but the colour is usually dark red changing to black instead of a greenish colour. This discoloration should not be mistaken for the greenish-yellow or black colora- tion imparted to the neighbouring organs by the bile soaking through the gall bladder. The pathological changes are still evident, hence it is necessary to go on with the examination. The viscera subsequently become greasy and softened, so that it is difficult to remove them entire. The rate of putrefaction in the internal organs varies greatly owing to the Sifferences in their structure as regards firmness, density and moisture. From his long experience Casper 25 has drawn up the following table show- ing the order in which the internal organs putrefy : — Those which putrefy soon Those which putrefy late 1. 2. 3. 4. 5. 6. 7. 8.
