of the stars, which has the greatest
weight with the superstitious Moors; consequently, when a patient,
either by their improper treatment, or the violence of his disease,
evinces symptoms of approaching dissolution, the doctor, with infinite
gravity, points out to the surrounding relations the star which, he
positively asserts, appears to summon the dying man to the bosom of
his Prophet. By this means he avoids reproach, since he has made it so
evident, that the poor man's time was come, and that nothing could
ward off the shafts of destiny. This apparently wonderful faculty of
prognostication, added to their exemplary mode of living, and liberal
donations to the poor and afflicted, operating upon the minds of the
blind and fanatic Moors, induces _them_ to consider their physicians
next to their saints, and to worship _them_ with nearly as much
reverence.

The Tweebs have each from two to six disciples, whom they instruct and
initiate in their secrets of the healing art. In their regular visits
to any town, they parade the streets with great pomp and gravity,
followed by a train of miserable objects, who pretend to have been
recently recovered from a long and dangerous illness by the
extraordinary skill of the doctor; while, in fact, their cadaverous
countenances and emaciated bodies seem to contradict their assertions,
and bear ample testimony that they are hurrying fast to that country,
"from whose bourne no traveller returns." Under the pretence of
charity, these poor wretches are supported by this Moorish
Aesculapius, while his views in so doing are entirely selfish; that
by their means he may better impose on the credulous, and obtain
considerable sums of money. When any one of them (by chance) effects
what he considers a great cure, it is communicated in a circular
letter to all the doctors in Barbary.

They select one of their elders every year, and appoint him to preside
over them. His business, for the time being, is to settle all their
controversies: he is the fountain of all justice among them; for as
they are looked upon to be petty saints, they are a privileged set of
men, and not in the least subject to either civil or military
jurisdiction. They possess the art of taming the monstrous serpents of
the country, and rendering them perfectly harmless: in short, their
profession is nothing but a system of the grossest empiricism.

Formerly the country could boast of having scientific astronomers;
