should　exhibit；　when　similarly　affected；　a　trace　of　the　same　expression；　together　with　some　tendency　to　utter　a　noise。　　For　it　is　not　at　all　unusual　for　animals　to　retain；　more　or　less　perfectly；　during　early　youth；　and　subsequently　to　lose；　characters　which　were　aboriginally　possessed　by　their　adult　progenitors；　and　which　are　still　retained　by　distinct　species；　their　near　relations。

Nor　is　it　an　anomalous　fact　that　the　children　of　savages　should　exhibit　a　stronger　tendency　to　protrude　their　lips；　when　sulky；　than　the　children　of　civilized　Europeans；　for　the　essence　of　savagery　seems　to　consist　in　the　retention　of　a　primordial　condition；　and　this　occasionally　holds　good　even　with　bodily　peculiarities。＇12＇　It　may　be　objected　to　this　view　of　the　origin　of　pouting；　that　the　anthropoid　apes　likewise　protrude　their　lips　when　astonished　and　even　when　a　little　pleased；　whilst　with　us　this　expression　is　generally　confined　to　a　sulky　frame　of　mind。　　But　we　shall　see　in　a　future　chapter　that　with　men　of　various　races　surprise　does　sometimes　lead　to　a　slight　protrusion　of　the　lips；　though　great　surprise　or　astonishment　is　more　commonly　shown　by　the　mouth　being　widely　opened。　As　when　we　smile　or　laugh　we　draw　back　the　corners　of　the　mouth；　we　have　lost　any　tendency　to　protrude　the　lips；　when　pleased；　if　indeed　our　early　progenitors　thus　expressed　pleasure。

A　little　gesture　made　by　sulky　children　may　here　be　noticed；　namely；　their　〃showing　a　cold　shoulder。〃　　This　has　a　different　meaning；　as；　I　believe；　from　the　keeping　both　shoulders　raised。　　A　cross　child；　sitting　on　its　parent's　knee；　will　lift　up　the　near　shoulder；　then　jerk　it　away；　as　if　from　a　caress；　and　afterwards　give　a　backward　push　with　it；　as　if　to　push　away　the　offender。　I　have　seen　a　child；　standing　at　some　distance　from　any　one；　clearly　express　its　feelings　by　raising　one　shoulder；　giving　it　a　little　backward　movement；　and　then　turning　away　its　whole　body。


_Decision　or　determination_。The　firm　closure　of　the　mouth　tends　to　give　an　expression　of　determination　or　decision　to　the　countenance。　No　determined　man　probably　ever　had　an　habitually　gaping　mouth。　Hence；　also；　a　small　and　weak　lower　jaw；　which　seems　to　indicate　that　the　mouth　is　not　habitually　and　firmly　closed；　is　commonly　thought　to　be　characteristic　of　feebleness　of　character。　　A　prolonged　effort　of　any　kind；　whether　of　body　or　mind；　implies　previous　determination；　and　if　it　can　be　shown　that　the　mouth　is　generally　closed　with　firmness　before　and　during　a　great　and　continued　exertion　of　the　muscular　system；　then；　through　the　principle　of　association；　the　mouth　would　almost　certainly　be　closed　as　soon　as　any　determined　resolution　was　taken。　Now　several　observers　have　noticed　that　a　man；　in　commencing　any　violent　muscular　effort；　invariably　first　distends　his　lungs　with　air；　and　then　compresses　it　by　the　strong　contraction　of　the　muscles　of　the　chest；　and　to　effect　this　the　mouth　must　be　firmly　closed。　　Moreover；　as　soon　as　the　man　is　compelled　to　draw　breath；　he　still　keeps　his　chest　as　much　distended　as　possible。
