1) The natural or fatigue states immediately preceding death of albino-rats, killed by electric shock or by hard blow, did not have any conclusive effect on the change in the amount of volatile basic nitrogen and amino-nitrogen in the muscle after death. Body deteriorated more rapidly in rats killed by blow than by electric shock.
2) In rats killed by electric shock, the number of bacteria was always more abundant in the fatigued group than in the normal group. However, comparative results of the degree of putrefaction by macroscopic observation was not always in accordance with the results of bacterial numbers but coincided with the amount of volatile basic nitrogen.
3) The value of pH transferred rapidly to acid region after death, and after 12-18hrs. (at 37°), it began to move toward alkaline region. In this case, pH value moved more in the alkaline side of fatigued group than the normal group.
4) Killing by electric shock transfers the muscle pH to acid region. In this case, muscle pH of normal rat showed more acidity than that of fatigued group. The cause of this phenomenon is due to the rapid increase of lactic acid by the sudden and strong excitation of the muscle by electric shock.
5) Rigor mortis in those killed by electric shock was stronger and stayed longer than in those killed by blow.
