an cured him
by the following Method: He took an hollow Ball of Wood, and filled it
with several Drugs; after which he clos'd it up so artificially that
nothing appeared. He likewise took a Mall, and after having hollowed the
Handle, and that part which strikes the Ball, he enclosed in them
several Drugs after the same Manner as in the Ball it self. He then
ordered the Sultan, who was his Patient, to exercise himself early in
the Morning with these _rightly prepared_ Instruments, till such time as
he should Sweat: When, as the Story goes, the Vertue of the Medicaments
perspiring through the Wood, had so good an Influence on the Sultan's
Constitution, that they cured him of an Indisposition which all the
Compositions he had taken inwardly had not been able to remove. This
Eastern Allegory is finely contrived to shew us how beneficial bodily
Labour is to Health, and that Exercise is the most effectual Physick. I
have described in my Hundred and Fifteenth Paper, from the general
Structure and Mechanism of an Human Body, how absolutely necessary
Exercise is for its Preservation. I shall in this Place recommend
another great Preservative of Health, which in many Cases produces the
same Effects as Exercise, and may, in some measure, supply its Place,
where Opportunities of Exercise are wanting. The Preservative I am
speaking of is Temperance, which has those particular Advantages above
all other Means of Health, that it may be practised by all Ranks and
Conditions, at any Season or in any Place. It is a kind of Regimen into
which every Man may put himself, without Interruption to Business,
Expence of Mony, or Loss of Time. If Exercise throws off all
Superfluities, Temperance prevents them; if Exercise clears the Vessels,
Temperance neither satiates nor overstrains them; if Exercise raises
proper Ferments in the Humours, and promotes the Circulation of the
Blood, Temperance gives Nature her full Play, and enables her to exert
her self in all her Force and Vigour; if Exercise dissipates a growing
Distemper, Temperance starves it.

Physick, for the most part, is nothing else but the Substitute of
Exercise or Temperance. Medicines are indeed absolutely necessary in
acute Distempers, that cannot wait the slow Operations of these two
great Instruments of Health; but did Men live in an habitual Course of
Exercise and Temperance, there would be but little Occasion for them.
Accordingly we find that those Parts of the World are the mo
