ng directions to Imlac, whom he
has adopted as his successor in the government of the elements and the
seasons, in these impressive words:

"Do not, in the administration of the year, indulge thy pride by
innovation; do not please thyself with thinking that thou canst make
thyself renowned to all future ages by disordering the seasons. The
memory of mischief is no desirable fame. Much less will it become thee
to let kindness or interest prevail. Never rob other countries of rain
to pour it on thine own. For us the Nile is sufficient.'

"Do you wonder, my friends, why I have chosen these passages, in which
the delusions of an insane astronomer are related with all the pomp of
the Johnsonian vocabulary, as the first lesson for the young person about
to enter on the study of the science and art of healing? Listen to me
while I show you the parallel of the story of the astronomer in the
history of medicine.

"This history is luminous with intelligence, radiant with benevolence,
but all its wisdom and all its virtue have had to struggle with the
ever-rising mists of delusion. The agencies which waste and destroy the
race of mankind are vast and resistless as the elemental forces of
nature; nay, they are themselves elemental forces. They may be to some

But the seasons and the tides and the tempests work their will on the
great scale upon whatever stands in their way; they feed or starve the
tillers of the soil; they spare or drown the dwellers by the shore; they

"The art of the physician can do much to remove its subjects from deadly
and dangerous influences, and something to control or arrest the effects
of these influences. But look at the records of the life-insurance
offices, and see how uniform is the action of nature's destroying
agencies. Look at the annual reports of the deaths in any of our great
cities, and see how their regularity approaches the uniformity of the
tides, and their variations keep pace with those of the seasons. The
inundations of the Nile are not more certainly to be predicted than the
