of manna in fair water, with the juice of a lemon to make it palatable.
Such gentle and unconfining evacuations would certainly prevent those
feverish attacks to which everybody at your age is subject.

By the way, I do desire, and insist, that whenever, from any
indisposition, you are not able to write to me upon the fixed days, that
Christian shall; and give me a TRUE account how you are. I do not expect
from him the Ciceronian epistolary style; but I will content myself with
the Swiss simplicity and truth.

I hope you extend your acquaintance at Paris, and frequent variety of
companies; the only way of knowing the world; every set of company
differs in some particulars from another; and a man of business must, in
the course of his life, have to do with all sorts. It is a very great
advantage to know the languages of the several countries one travels in;
and different companies may, in some degree, be considered as different
countries; each hath its distinctive language, customs, and manners: know
them all, and you will wonder at none.

Adieu, child. Take care of your health; there are no pleasures without
it.

LETTER CLX

LONDON, February 20, O. S. 1752.

MY DEAR FRIEND: In all systems whatsoever, whether of religion,
government, morals, etc., perfection is the object always proposed,
though possibly unattainable; hitherto, at least, certainly unattained.
However, those who aim carefully at the mark itself, will unquestionably
come nearer it, than those who from despair, negligence, or indolence,

than those desponding or indolent spirits, who foolishly say to
themselves: Nobody is perfect; perfection is unattainable; to attempt it
is chimerical; I shall do as well as others; why then should I give
myself trouble to be what I never can, and what, according to the common
course of things, I need not be, PERFECT?

I am very sure that I need not point out to you the weakness and the
folly of this reasoning, if it deserves the name of reasoning. It would
discourage and put a stop to the exertion of any one of our faculties. On
the contrary, a man of sense and spirit says to himself: Though the point
of perfection may (considering the imperfection of our nature) be
unattainable, my care, my endeavors, my attention, shall not be wanting
to get as near it as I can. I will a
