There was a curious case of lightning-stroke reported at Cole Harbor, Halifax. A diver, while at work far under the surface of the water, was seriously injured by the transmission of a lightning-stroke, which first struck the communicating air pump to which the diver was attached. The man was brought to the surface insensible, but he afterward recovered.
Permanent Effect of Lightning on the Nervous System.--MacDonald mentions a woman of seventy-eight who, some forty-two years previous, while ironing a cap with an Italian iron, was stunned by an extremely vivid flash of lightning and fell back unconscious into a chair. On regaining consciousness she found that the cap which she had left on the table, remote from the iron, was reduced to cinders. Her clothes were not burned nor were there any marks on the skin. After the stroke she felt a creeping sensation and numbness, particularly in the arm which was next to the table. She stated positively that in consequence of this feeling she could predict with the greatest certainty when the atmosphere was highly charged with electricity, as the numbness increased on these occasions. The woman averred that shortly before or during a thunder storm she always became nauseated. MacDonald offers as a physiologic explanation of this case that probably the impression produced forty-two years before implicated the right brachial plexus and the afferent branches of the pneumogastric, and to some degree the vomiting center in the medulla; hence, when the atmosphere was highly charged with electricity the structures affected became more readily impressed. Camby relates the case of a neuropathic woman of thirty-eight, two of whose children were killed by lightning in her presence. She herself was unconscious for four days, and when she recovered consciousness, she was found to be hemiplegic and hemianesthetic on the left side. She fully recovered in three weeks. Two years later, during a thunder storm, when there was no evidence of a lightning-stroke, she had a second attack, and three years later a third attack under similar circumstances.
There are some ocular injuries from lightning on record. In these cases the lesions have consisted of detachment of the retina, optic atrophy, cataract, hemorrhages into the retina, and rupture of the choroid, paralysis of the oculomotor muscles, and paralysis of the optic nerve. According to Buller of Montreal, such injuries may arise from the mechanic violence sustained by the patient rather than by the thermal or chemic action of the current. Buller describes a case of lightning-stroke in which the external ocular muscles, the crystalline lens, and the optic nerve were involved. Godfrey reports the case of Daniel Brown, a seaman on H.M.S. Cambrian. While at sea on February 21, 1799, he was struck both dumb and blind by a lightning-stroke. There was evidently paralysis of the optic nerve and of the oculomotor muscles; and the muscles of the glottis were also in some manner deprived of motion.
That an amputation can be perfectly performed by a lightning-stroke is exemplified in the case of Sycyanko of Cracow, Poland. The patient was a boy of twelve, whose right knee was ankylosed. While riding in a field in a violent storm, a loud peal of thunder caused the horse to run away, and the child fell stunned to the ground. On coming to his senses the boy found that his right leg was missing, the parts having been divided at the upper end of the tibia. The wound was perfectly round and the patella and femur were intact. There were other signs of burns about the body, but the boy recovered. Some days after the injury the missing leg was found near the place where he was first thrown from the horse.
The therapeutic effect of lightning-stroke is verified by a number of cases, a few of which will be given. Tilesius mentions a peculiar case which was extensively quoted in London. Two brothers, one of whom was deaf, were struck by lightning. It was found that the inner part of the right ear near the tragus and anti-helix of one of the individuals was scratched, and on the following day his hearing returned. Olmstead quotes the history of a man in Carteret County, N.C., who was seized with a paralytic affection of the face and eyes, and was quite unable to close his lids. While in his bedroom, he was struck senseless by lightning, and did not recover until the next day, when it was found that the paralysis had disappeared, and during the fourteen years which he afterward lived his affection never returned.
There is a record of a young collier in the north of England who lost his sight by an explosion of gunpowder, utterly destroying the right eye and fracturing the frontal bone. The vision of the left eye was lost without any serious damage to the organ, and this was attributed to shock. On returning from Ettingshall in a severe thunder storm, he remarked to his brother that he had seen light through his spectacles, and had immediately afterward experienced a piercing sensation which had passed through the eye to the back of the head. The pain was brief, and he was then able to see objects distinctly. From this occasion he steadily improved until he was able to walk about without a guide.
