THE NAVAL STRING should receive the attention of the nurse; within an hour of the time it is at first tied, she should examine the dressing to see if there has been any bleeding. If it bleeds, and the doctor is not at hand, retie with a stout cord, drawing it quite tight. Each morning, when the child is bathed, lift up the naval string with the rag dressing and insert a little nice fresh tallow under it. When it is loose remove it, but use no means to cause the separation. The naval is sometimes a little sore, but seldom needs any dressing more than simply vaseline or tallow. AT NIGHT a child should be entirely undressed, and its clothing replaced by other garments, those that are loose, light, and sufficiently warm for it while it is under the bedclothes. For a very young child the proper night-dress is a loose slip; when older, a pair of drawers, fitting up well around the neck and covering the body and limbs, is a good article. The clothing worn during the day should not be worn at night, and the clothing when soiled should be immediately changed. Whenever the child seems disposed to sleep, this should be encouraged. Never arouse a child suddenly from its sleep. Be careful that there is no unnecessary noises to disturb its sleeping. Time the bathing and dressing so that the little one may not be unnecessarily disturbed. But never give soothing syrups, anodynes for infants, or other nostrums to induce them to sleep. If the child is restless, endeavor to ascertain if there is not some cause that can be removed, such as tight clothing, etc. PREMATURE INFANTS may, under favorable circumstances and assiduous care, live and thrive. Immediately after birth the child should be placed in a warm bath, and then wrapped in cotton. The baths should be warmer than usual, and must be frequently repeated. Awaken the child every one or two hours to feed it. Milk (woman’s milk is the best) must be given it by a teaspoon. With a view to the better development of the lungs, it may be excited to cry by a slight irritation. Do not bring such children into the open air for several months after the birth, as their passages are readily affected. PART II. ANATOMY AND PHYSIOLOGY OF THE FEMALE ORGANS AND FŒTAL DEVELOPMENT. CHAPTER I. OF THE PELVIS. The formative organs of generation are situated within a large cavity, called the cavity of the pelvis, the walls of which are composed of bones and soft parts. This basin (in Latin, _pelvis_) is an irregular, long cavity, situated at the base of the spinal column, and above the inferior extremities. In the adult the bony pelvis may be divided into four parts or bones, viz: the os sacrum, two ossa innominata, and the os coccygis, but in early life they are more minutely divisible. THE SACRUM.
