The object is to keep the infant sufficiently warm with pure air; it therefore ought to have free access to its mouth, and the atmosphere of the whole room should be kept sufficiently warm to allow the child to breathe it freely: in winter, therefore, there must always be a fire in the nursery.

On the other hand, it must not be forgotten, that too warm clothing is a source of disease,sometimes even of the same diseases which originate in exposure to cold,and often renders the frame more susceptible of the impressions of cold, especially of cold air taken into the lungs.

AIR AND EXERCISE.

IN INFANCY.The respiration of a pure air is at all times, and under all circumstances, indispensable to the health of the infant.

The proper time for taking the infant into the open air must, of course, be determined by the season of the year, and the state of the weather.

IN CHILDHOOD.When the child has acquired sufficient strength to take active exercise, he can scarcely be too much in the open air; the more he is habituated to this, the more capable will he be of bearing the vicissitudes of the climate.

Expose the surface of the part to the external air, so that a coagulum of blood may form at the orifice: this simple mode will frequently arrest it.

When, however, the object is not to excite perspiration, the child may be dressed in his ordinary clothing, but should not be allowed to expose himself to the open air for at least an hour.

The child should be much in the open air.

It is far better, if the child is restless at night, to have it frequently taken out of its cot, and carried about in an airy room; for the cool air, and change of posture, will do much to allay the feverishness and restlessness of the child.

As the winter advances, the air-tubes of the lungs, and the lungs themselves, are liable to become the seat of disorder; and those signs will present themselves, which have been pointed out in the previous section as characteristic of such attacks.

Its head is to be slightly extended, and the nostrils held between the fingers and thumb of one hand, whilst with the fingers of the other slight pressure is to be made upon the pit of the stomach, so as to prevent the air from passing into that organ.

The lungs of the child are now to be filled with air, by the operator applying his own lipswith a fold of silk or muslin intervening, for the sake of cleanlinessto those of the child, and then simply blowing in its mouth, he is to propel the air from his own chest into that of the infant.

This is to be remedied by the introduction of the fore-finger to the upper and back part of the child's tongue, and gently pressing it downwards and forwards, by which the difficulty will be removed, and the air again passes.

The temperature of the bath should be about 100 degrees; and if, upon plunging the infant into it, it fortunately excite the respiratory effort, it should then be taken out, rubbed with dry but hot flannels, and, when breathing is fully established, laid in a warm bed, or, what is still better, in its mother's bosom; letting it, however, have plenty of air.

Errors in diet, a want of proper attention to the state of the skin, insufficiency of air and exercise, in fine, a neglect of those general principles which have been laid down for the management of health, and upon the observance of which the due and healthy performance of every function of the body depends, are the sources of bowel derangements, and particularly, at this age, of costiveness.

This is of importance in the mildest cases; but in the more severe forms of this disease, in which the throat is much affected, the constant and free admission of pure air will have a most decided and marked good effect upon the symptoms.

The air should be renewed, therefore, from time to time.

The bed-room should be capacious and well ventilated; fresh air frequently admitted; and if the season of the year permit, and there is no dampness of atmosphere, a window should be constantly open during the day: it is also desirable to keep the chamber darkened in all cases, as there is always a tendency to inflammation of the eyes.

The most frequent complication with hooping-cough is inflammation of the air-tubes of the lungs.

For this purpose it must be sponged night and morning throughout the whole period of teething; a horse-hair pillow used in the cot; and nothing but a light straw hat should be worn, except in winter, The diet should be moderate, and carefully regulated after leaving the breast, and the child should be as much as possible in the open air.

Assuming an air of interest, he inquired if the captain knew where the major was confined.

"You see, Smash," said Maud, pointing to her sister with a strange resolution, "she must have air, and a little waterand she has salts about her, I know.
