Careful autopsies were made in the cases of the criminals executed by electricity, but no important changes caused by the electric current have been detected either macroscopically or microscopically. A few petechial spots (Tardieu’s spots) are apt to be found underneath the pericardium in the heart tissue and sometimes beneath the pleura. The organs were not extremely congested. In the case of Jugigo the vessels of the spinal cord and its membranes contained if anything less blood than usual. In this case the amount of blood found in the brain seems to have been about normal, the vessels of the dura were moderately dilated and those of the pia “in a medium state of congestion.” In the case of Kemmler the portion of the intracranial contents underneath the head-electrode was somewhat affected directly by the heat, the meningeal vessels in the dura were carbonized, and the brain cortex was sensibly hardened to one-sixth of its depth, “where there was a broken line of vascularity.” The post-mortem temperature in this case seems to have remained unusually high, being 97° F. in the fourth ventricle and 99° F. at the back of the neck three hours after death in a room where the temperature was only 83°.
In autopsies after death by lightning the results are in general analogous. The brain and its membranes may be anæmic or congested. Effusions of blood may be found beneath the dura or in the brain substance itself, due to the laceration or injury of vessels. Rupture of the brain is said to have occurred, and Phayre reports a case in which the left hemisphere was entirely destroyed and changed into a dark gray homogeneous fluid mass, only a small portion of the corpus callosum remaining. No extravasation of blood, laceration of the vessels or membranes, or injury of the bones was detected.
Ecchymotic spots are frequently found beneath the serous membranes, pericardium, pleura, and peritoneum.
Schmitz states that parenchymatous inflammation of the internal organs may occur, and Sullivan reports a case where the stomach was found to be gangrenous over a large surface, the patient having lived several days. Cases of rupture of the heart, the liver, and the spleen are reported.
