trong odor. Musk, a substance possessing the most penetrating
odor and used in therapeutics, is obtained from the preputial follicles
of the musk-deer of Thibet; and castor, a substance less penetrating,
is obtained from the preputial sacs of the beaver. Virgin moths
(Bombyx) carried in boxes in the pockets of entomologists will on wide
commons cause the appearance of males of the same species.

Bulimia is excessive morbid hunger, also called canine appetite. While
sometimes present in healthy people, it is most often seen in idiots
and the insane, and is a symptom of diabetes mellitus. Mortimer
mentions a boy of twelve who, while laboring under this affliction, in
six days devoured food to the extent of 384 pounds and two ounces. He
constantly vomited, but his craving for food was so insatiable that if
not satisfied he would devour the flesh off his own bones. Martyn,
Professor of Botany at Cambridge in the early part of the last century,
tells of a boy ten years old whose appetite was enormous. He consumed
in one week 373 pounds of food and drink. His urine and stools were
voided in normal quantities, the excess being vomited. A pig was fed on
what he vomited, and was sold in the market. The boy continued in this
condition for a year, and at last reports was fast failing. Burroughs
mentions a laborer at Stanton, near Bury, who ate an ordinary leg of
veal at a meal, and fed at this extravagant rate for many days
together. He would eat thistles and other similar herbs greedily. At
times he would void worms as large as the shank of a clay-pipe, and
then for a short period the bulimia would disappear.

Johnston mentions a case of bulimia in a man who devoured large
quantities of raw flesh. There is an instance on record of a case of
canine appetite in which nearly 400 pounds of solid and fluid elements
were taken into the body in six days and again ejected. A recovery was
effected by giving very concentrated food, frequently repeated in small
quantities. Mason mentions a woman in St. Bartholomew's Hospital in
London in the early part of this century who was wretched unless she
was always eating. Each day she consumed three quartern-loaves, three
pounds of beef-steak, in addition to large quantities of vegetables,
meal, etc., and water. Smith describes a boy of fourteen who ate
continuously fifteen hours out of the twenty-four, and who had eight
bowel movements each day. One year previous his weight was 105 pounds,
