Laughing, like crying, has a good effect on the infantile lungs; nor is it less salutary in other respects. "Laugh and be fat," an old adage, has its meaning, and also its philosophy.

There is an excess, however, to which laughing, no less than crying, may be carried, and which we cannot too carefully avoid. But how little to be envied—how much to be pitied—are they who consider it a weakness and a sin to laugh, and in the plenitude of their wisdom, tell us that the Saviour of mankind never laughed. When I hear this last assertion, I am always ready to ask, whether the individual who makes it has read a new revelation or a new gospel; for certainly none of the sacred books which I have seen give us any such information.

But I will not dwell here. The common notion on this subject, if not ridiculous, is certainly strange. I will only add, that, come into vogue as it might have done, there is no opinion more unfounded than the very general one among adults, that children should be uniformly grave; and that just in proportion as they laugh and appear frolicsome, just in the same proportion are they out of the way, and deserving of reprehension.

It is strange that it should be so, but I have seen many parents who were miserable because their children were sportive and joyful. Oh, when will the days of monkish sadness and austerity be over; and the public sentiment in the christian world get right on this subject!

State of the mind.—SEC. 9. Quality of sleep.—SEC. 10. Quantity of sleep.

Not a few persons consider all rules relative to sleep as utterly futile. They regard it as so much of a natural or animal process, that if we are let alone we shall seldom err, at any age, respecting it. Rules on the subject, above all, they regard as wholly misplaced.
