Pasteur discovered that the virulence of the virus of rabies could be
attenuated in passing it through different species of animals, and also
that inoculation of this attenuated virus had a decided prophylactic
effect on the disease; hence, by cutting the spinal cord of inoculated
animals into fragments a few centimeters long, and drying them, an
emulsion could be made containing the virus. The patients are first
inoculated with a cord fourteen days old, and the inoculation is
repeated for nine days, each time with a cord one day fresher. The
intensive method consists in omitting the weakest cords and giving the
inoculations at shorter intervals. As a curious coincidence, Pliny and
Pasteur, the ancient and modern, both discuss the particular virulence
of saliva during fasting.

There is much discussion over the extent of injury a shark-bite can
produce. In fact some persons deny the reliability of any of the
so-called cases of shark-bites. Ensor reports an interesting case
occurring at Port Elizabeth, South Africa. While bathing, an expert
swimmer felt a sharp pain in the thigh, and before he could cry out,
felt a horrid crunch and was dragged below the surface of the water. He
struggled for a minute, was twisted about, shaken, and then set free,
and by a supreme effort, reached the landing stairs of the jetty,
where, to his surprise, he found that a monstrous shark had bitten his
leg off. The leg had been seized obliquely, and the teeth had gone
across the joints, wounding the condyles of the femur. There were three
marks on the left side showing where the fish had first caught him. The
amputation was completed at once, and the man recovered. Macgrigor
reports the case of a man at a fishery, near Manaar, who was bitten by
a shark. The upper jaw of the animal was fixed in the left side of the
belly, forming a semicircular wound of which a point one inch to the
left of the umbilicus was the upper boundary, and the lower part of the
upper third of the thigh, the lower boundary. The abdominal and lumbar
muscles were divided and turned up, exposing the colon in its passage
across the belly. Several convolutions of the small intestines were
also laid bare, as were also the three lowest ribs. The gluteal muscles
were lacerated and torn, the tendons about the trochanter divided,
laying the bone bare, and the vastus externus and part of the rectus of
the thigh were cut across.
