Le Conte mentions the case of a negress who was struck by lightning August 19； 1842； on a plantation in Georgia。 For years before the reception of the shock her health had been very bad； and she seemed to be suffering from a progressive emaciation and feebleness akin to chlorosis。 The difficulty had probably followed a protracted amenorrhea； subsequent to labor and a retained placenta In the course of a week she had recovered from the effects of lightning and soon experienced complete restoration to health； and for two years had been a remarkably healthy and vigorous laborer。 Le Conte quotes five similar cases； and mentions one in which a lightning…shock to a woman of twenty…nine produced amenorrhea； whereas she had previously suffered from profuse menstruation； and also mentions another case of a woman of seventy who was struck unconscious； the catamenial discharge which had ceased twenty years before； was now permanently reestablished； and the shrunken mammae again resumed their full contour。
A peculiar feature or superstition as to lightning…stroke is its photographic properties。 In this connection Stricker of Frankfort quotes the case of Raspail of a man of twenty…two who； while climbing a tree to a bird's nest； was struck by lightning； and afterward showed upon his breast a picture of the tree； with the nest upon one of its branches。 Although in the majority of cases the photographs resembled trees； there was one case in which it resembled a horse…shoe； another； a cow； a third； a piece of furniture； a fourth； the whole surrounding landscape。 This theory of lightning…photographs of neighboring objects on the skin has probably arisen from the resemblance of the burns due to the ramifications of the blood…vessels as conductors； or to peculiar electric movements which can be demonstrated by positive charges on lycopodium powder。
A lightning…stroke does not exhaust its force on a few individuals or objects； but sometimes produces serious manifestations over a large area； or on a great number of people。 It is said that a church in the village of Chateauneuf； in the Department of the Lower Alps； in France； was struck by three successive lightning strokes on July 11； 1819； during the installation of a new pastor。 The company were all thrown down； nine were killed and 82 wounded。 The priest； who was celebrating mass； was not affected； it is believed； on account of his silken robe acting as an insulator。 Bryant of Charlestown； Mass。； has communicated the particulars of a stroke of lightning on June 20； 1829； which shocked several hundred persons。 The effect of this discharge was felt over an area of 172；500 square feet with nearly the same degree of intensity。 Happily； there was no permanent injury recorded。 Le Conte reports that a person may be killed when some distanceeven as far as 20 miles away from the stormby what Lord Mahon calls the 〃returning stroke。〃
Skin…grafting is a subject which has long been more or less familiar to medical men； but which has only recently been developed to a practically successful operation。 The older surgeons knew that it was possible to reunite a resected nose or an amputated finger； and in Hunter's time tooth… replantation was quite well known。 Smellie has recorded an instance in which； after avulsion of a nipple in suckling； restitution was effected。 It is not alone to the skin that grafting is applicable； it is used in the cornea； nerves； muscles； bones； tendons； and teeth。 Wolfer has been successful in transplanting the mucous membranes of frogs； rabbits； and pigeons to a portion of mucous membrane previously occupied by cicatricial tissue； and was the first to show that on mucous surfaces； mucous membrane remains mucous membrane； but when transplanted to skin； it becomes skin。 Attempts have been made to transplant a button of clear cornea of a dog； rabbit； or cat to the cornea of a human being； opaque as the result of ophthalmia； and von Hippel has devised a special method of doing this。 Recently Fuchs has reported his experience in cornea…grafting in sections； as a substitute for von Hippel's method； in parenchymatous keratitis and corneal staphyloma； and though not eminently successful himself； he considers the operation worthy of trial in cases that are without help； and doomed to blindness。
John Hunter was the first to perform the implantation of teeth； and Younger the first to transplant the teeth of man in the jaws of man； the initial operation should be called replantation； as it was merely the replacement of a tooth in a socket from which it had accidentally or intentionally been removed。 Hunter drilled a hole in a cock's comb and inserted a tooth； and held it by a ligature。 Younger drilled a hole in a man's jaw and implanted a tooth； and proved that it was not necessary to use a fresh tooth。 Ottolengni mentions the case of a man who was struck by a ruffian and had his two central incisors knocked out。 He searched for them； washed them in warm water； carefully washed the teeth…sockets； and gently placed the teeth back in their position； where they remained firmly attached。 At the time of report； six years after the accident； they were still firmly in position。 Pettyjohn reports a successful case of tooth…replantation in his young daughter of two； who fell on the cellar stairs； completely excising the central incisors。 The alveolar process of the right jaw was fractured； and the gum lacerated to the entire length of the root。 The teeth were placed in a tepid normal saline solution； and the child chloroformed； narcosis being induced in sleep； the gums were cleaned antiseptically； and 3 1/2 hours afterward the child had the teeth firmly in place。 They had been out of the mouth fully an hour。 Four weeks afterward they were as firm as ever。 By their experiments Gluck and Magnus prove that there is a return of activity after transplantation of muscle。 After excision of malignant tumors of muscles； Helferich of Munich； and Lange of New York； have filled the gap left by the excision of the muscle affected by the tumor with transplanted muscles from dogs。 Gluck has induced reproduction of lost tendons by grafting them with cat…gut； and according to Ashhurst； Peyrot has filled the gaps in retracted tendons by transplanting tendons； taken in one case from a dog； and in another from a cat。
Nerve…grafting； as a supplementary operation to neurectomy； has been practiced； and Gersung has transplanted the nerves of lower animals to the nerve stumps of man。
Bone…grafting is quite frequently practiced； portions from a recently amputated limb； or portions removed from living animals； or bone…chips； may be used。 Senn proposed decalcified bone…plates to be used to fill in the gaps。 Shifting of the bone has been done； e。g。； by dividing a strip of the hard palate covered with its soft parts； parallel to the fissure in cleft palate； but leaving unsevered the bony attachments in front； and partially fracturing the pedicle； drawing the bony flaps together with sutures； or； when forming a new nose； by turning down with the skin and periosteum the outer table of the frontal bone； split off with a chisel； after cutting around the part to be removed。 Trueheart reports a case of partial excision of t
