I 210' EXPBESSION OF HIGH SPIRITS. CHAP. VIII. I ' '.* I , at 'about the same age, viz. forty-five days; and in a I third, at a somewhat earlier age. The second infant, \ - when sixty-five days old, smiled much more broadly and plainly than did the one first mentioned at the same ^ ' age; and even at this early age uttered noises very like I . laughter. In this gradual acquirement, by infants, of I : , the habit of laughing, we have a case in some degree analogous to that of weeping. As practice is requisite with the ordinary movements of the body., such as walk- ing, so it seems to be with laughing and weeping. The art of screaming, on the other hand, from being of serv- ice to infants, has become finely developed from the earliest days. High spirits , cheerfulness. — A man in high spirits, though he may not actually smile, commonly exhibits some tendency to the retraction of the corners of his mouth. From the excitement of pleasure, the circula- tion becomes more rapid; the eyes are bright, and the colour of the .Pace rises. The brain, being stimulated by the increased flow of blood, reacts on the mental powers; lively ideas pass still more rapidly through the mind, and the affections are warmed. I heard a child, a little under four years old, when asked what was meant by being in good spirits, answer, " It is laughing, talking, and kissing." It would be difficult to give a truer and more practical definition. A man in this state holds his body erect, his head upright, and his eyes open.
