'My Friend might have darted other Objections, 
and which indeed are, in feme meafure, Exceptions 
to the general Sydem I have laid down ; but which 
cannot invalidate the lead Part of it, when the Rea- 
fons for them are explain'd. Fir ft ^ He may argue, 
that there are many Maniacs , who are in a condant 
State of Madnefs, and yet the Mufcles of the Face 
are in no-wife didorted, nor any other Appearance 
of Wildnefs in the Countenance than what the Eyes 
produce : But this happens only becaufe the morbid 
Madnefs is involuntary; whereas all the Paffions of 
the Mind, which correfpond with, and aduate, the 
Mufcles of the Face, are voluntary, and, confequently, 
draw the Mufcles fubfervient to each particular one 
into Confent. The Player, acting his Part with 
Judgment, is capable of producing thefe Effeds,- he 
can artfully put on the Grimace which bed exprelfes 
or accompanies the Character he is to reprefent ; as 
the Man, whofe natural Temper alfo leads him to 
wear the Afped fuited to his State of Mind, what- 
foever it be; and as fuch a one can occafionally 
change his Afped, tho* but for a little time, from its 
cudomary State, it is plain, that the cudomary Paf- 
fions of the Mind arc fird voluntary, and the Adions 
of their fcveral fubfervient Mufcles are fo too: And, 
zdly> There can be no reigning Gedure of the Face 
difccrnable in Idiots exprefllve of any Pallion ; be- 
caufe they can have no fettled Intention to produce 
one, or render it cudomary in their general Con- 
dud;
