gether; therefore, in moving them evef
each other, one of the bodies must be raised
up or its prominence broken off-this is
termed friction.
Friction is, in some measure, in prop6f4
ton to the weight of bodies Or pressure
against each other. 1t does not increase
in proportion to the surface, though it may
in some measure increase in proportion to
the velocity.
When the polished steel moves on the
same, or on pewter, properly oiled, the fric4
ton is about one-fourth the weight; on cops
per or lead, one-ffth the weight or brass,
one sixth. Metals have the most friction
when they move on metals of the same
kind. The least friction is generated when
polished iron moves on brass or a compost.
ton in certain proportions of copper and
spelter; gudgeons and piyots of wheels,
and the axles OF friction rollers, should
be made of polished irons in preference to
steel.
Tne most proper uHguenr To prevent frie-s
ton is lard or tallow, when the surfaces are
of wood, and oil when they are made of
metal When the forces with which the
surfaces are pressed together are very
great, tallow will diminish the friction more
than lard. The best method of applying
the unguent is to cover the rubbing surfaces
with as thin stratum as possible, in order
TO make the friction uniform. In small
works of wood, the iDerposition of the
powder of black lead is found very useful.
The friction of single lever is very small,
that of the wheel and axle in proportion to
the weight, velocity, and diameter of the
axis. That of pulleys is very great, on ac-
count Of the smallness of their diameters in
to their axis, their bearing
against their block, and from the wearing
of their boles and axes.
The friction is very great in the wedge
and screw. Screws with sharp threads
have more friction than those with square
ones-and endless screws more friction
than either.
PROPORTIONS OF GOOD NOSE AND
MOUTH. Now the nose according to the
justice of nature, should be no longer than
the lip and ears, and the third part of the
face in length, and the thirtieth part of the
length of the whole body it should not ex-
coed in length half that distance which in-
terposeth between the external angle Of
both the eyes therefore, the length of the
nose should answer in sesquialtera pros
portion, the length of the eye and the de.
duction of the mouth nor should it exI
coed in length beyond the measure of its
circumference at the bottom. A long nose,
indeed may be of some advantage to the
sense Of smelling, as appears in the noses
of bloodhounds yet, for the scent Of man;
that length is sufficient which consists with
beauty, and may be reconciled with the
of natures symmetry, beyond
which who endeavors to extend the nose
renders himself guilty of great transgres.
sion; az on the contrary, they also do, who
labor to prohibit the natural extending of
the nose upon any pretenses of beauty
whatsoever.
The deduction or longitude of the mouth
should but equal the longitude of the eye,
which extends from the outward angle to
the lacrymall, so that the longitude of the
mouth is duple to the ninth part of the lon
gitude of the face, and the nose should bear
a sesquialtera proportion unto it; and the
width of the mouth should be but as much
again as the bottom of the nose near the
mouth, the circumference of it double, and
the deduction of it treble to the longitude of
the nose so that the whole longitude of

ton to the compass of the mouth, or the
space contained between the corners Of the
eye, for this space should equal the COM
pass, also, of the mouth, and the circum.
ference of the ears ought to be in unison;
the first joint, likewise towards the hand in
the middle finger, should be as much as the
mouth, if you measure the bow Of the lip
with thread; for if you measure it right
in the longitude of the empty mouth, that
part of the finger would exceed it.-JohH

There are in every country morose beings,
who are always demonstrating ruin. There
was one of this stamp at Philadelphia, He was

of wisdom, and very grave manner Of speak

him not but he stopped one day at my door,
and asked if was the young man who had
lately opened new printing house. Upon my
answering in the affirmative, he said that he
was very sorry for me, as it was an expensive
undertaking, and that the money that had been
laid out would be lost Philadelphia being d
place falling into decay; its inhabitants having
all, or nearly all of them been obliged to call
together their creditors. That he knew from
uhdohbted fact, the circumstances which might
lead us to suppose the contrary, such as new
buildings, and the advanced price Of rent, to be
deceitful appearances, which in reality contrib
uted to hasten the general ruin and he gave
me strong detail of misfortunes existing,
or which were soon to take place, that he
left me almost in state Of despair. Had
known this man before entered into trade,
should doubtless never have ventured He cone

and to declaim in the same style, refusing for
