oined the study of
astrology with it, because I never knew a physician recommend himself
to the public who had not a sister art to embellish his knowledge in
medicine. It has been commonly observed, in compliment to the ingenious
of our profession, that Apollo was god of verse as well as physic; and
in all ages, the most celebrated practitioners of our country were the
particular favourites of the Muses. Poetry to physic is indeed like the
gilding to a pill; it makes the art shine, and covers the severity of
the doctor with the agreeableness of the companion.

The very foundation of poetry is good sense, if we may allow Horace to
be a judge of the art.

"Scribendi recte sapere est et principium et fons."
HOR. ARS POET. 309.

"Such judgment is the ground of writing well."
ROSCOMMON.

And if so, we have reason to believe that the same man who writes well
can prescribe well, if he has applied himself to the study of both.
Besides, when we see a man making profession of two different sciences,
it is natural for us to believe he is no pretender in that which we are
not judges of, when we find him skilful in that which we understand.

Ordinary quacks and charlatans are thoroughly sensible how necessary it
is to support themselves by these collateral assistances, and therefore
always lay their claim to some supernumerary accomplishments, which are
wholly foreign to their profession.

About twenty years ago, it was impossible to walk the streets without
having an advertisement thrust into your hand, of a doctor "who
was arrived at the knowledge of the 'Green and Red Dragon,' and had
discovered the female fern-seed." Nobody ever knew what this meant; but
the "Green and Red Dragon" so amused the people, that the doctor lived
very comfortably upon them. About the same time there was pasted a very
hard word upon every corner of the streets. This, to the best of my
remembrance, was

TETRACHYMAGOGON,

which drew great shoals of spectators about it, who read the bill that
it introduced with unspeakable curiosity; and when they were sick, would
have nobody but this learned man for their physician.

I once received an advertisement of one "who had studied thirty years
by candle-light for the good of his countrymen." He might have studied
twice as long by daylight and never have been taken notice of. But
elucubrations cannot be
