Shall they practice reading, sewing, and the like exercises in rooms so poorly lighted that a person coming from the open air can scarcely discern one object from another?

Shall they remain in-doors as much of the time as is possible, lest the light should render their skin of a somewhat less delicate hue?

Shall they, when they must needs come out for a walk, wear a thick, heavy, and perhaps three-double vail, in order to preserve that delicacy, of which women too often appear to be so fond?

Shall they go on thus keeping up this so-called beauty and delicateness, even if it be at the expense of ennui, debility, nervousness, and general ill health?

Or, on the other hand, shall they go often and freely into the open air, walking miles every day; or what is perhaps better, engage in active, and, if possible, out-door pursuits, a part of each day?

In the one case, health is, as a general thing, easy to obtain; in the other, impossible.

As children know by instinct, and physiologists by scientific facts, human beings must go often into the open light of day, in order to insure firm and enduring bodily health.

Nor are the good effects of light less important on the feelings, habits, and mental manifestations of the individual.

AIR AND EXERCISE.

Would that I could now impress upon your minds, in some good degree, the importance of AIR and EXERCISE in pregnancy.
