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 distance--even as far as 20 miles away from the
storm--by 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.
