The clothing must be changed daily.—­It is eminently conducive to good health that a complete change of dress should be made every day.  If this is not done, washing will, in a great measure, fail in its object, especially in insuring freedom from skin diseases.

In childhood.—­The clothing of the child should possess the same properties as that of infancy.  It should afford due warmth, be of such materials as do not irritate the skin, and so made as to occasion no unnatural constriction.

In reference to due warmth, it may be well again to repeat, that too little clothing (that state of semi-nudity which the vanity of some parents encourage) is frequently productive of the most sudden attacks of active disease; and that children who are thus exposed with naked breasts and thin clothing in a climate so variable as ours are the frequent subjects of croup, and other dangerous affections of the air-passages and lungs.  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.  Regulate the clothing, then, according to the season; resume the winter dress early; lay it aside late; for it is in spring and autumn that the vicissitudes in our climate are greatest, and congestive and inflammatory complaints most common.

With regard to material (as was before observed), the skin will at this age bear flannel next to it; and it is now not only proper, but necessary.  It may be put off with advantage during the night, and cotton maybe substituted during the summer, the flannel being resumed early in the autumn.  If from very great delicacy of constitution it proves too irritating to the skin, fine fleecy hosiery will in general be easily endured, and will greatly conduce to the preservation of health.

It is highly important that the clothes of the boy should be so made that no restraints shall be put on the movements of the body or limbs, nor injurious pressure made on his waist or chest.  All his muscles ought to have full liberty to act, as their free exercise promotes both their growth and activity, and thus insures the regularity and efficiency of the several functions to which these muscles are subservient.

The same remarks apply with equal force to the dress of the girl; and happily, during childhood, at least, no distinction is made in this matter between the sexes.  Not so, however, when the girl is about to emerge from this period of life; a system of dress is then adopted which has the most pernicious effects upon her health, and the development of the body, the employment of tight stays, which impede the free and full action of the respiratory organs, being only one of the many restrictions and injurious practices from which in latter years they are thus doomed to suffer so severely.
