If an abortion be threatened from any cause, the same general practice must be adopted as recommended for _flooding_, the indications being the same. I believe myself that in most cases, except from accidental violence or internal disease, miscarriage may be averted. I knew a lady who had miscarried many times, always at the same period, who avoided it at last by simply _preventing constipation_ from the first commencement of pregnancy, and by using an enema every evening of warm starch and water, pretty thick, with about thirty drops of laudanum. This was administered by means of a common injection pipe, just before going to bed, and continued till after she had quickened, and repeated occasionally after that, if she felt any premonitory symptoms of uterine disturbance. If the patient be of a full habit, she should also, _from the very beginning_, live low, keep the bowels free, and the skin in good action, and take gentle regular exercise in the open air. When all the means used are found of no avail, and it becomes evident that the fœtus must be expelled, every endeavor should be used to assist nature in its removal as early and as safely as possible. For this purpose the same treatment, as far as practicable, must be pursued as in a real labor. If the hand can be conveniently introduced, without undue force, it may be so, to remove clots, or to take hold of any part of the fœtus which may present, and assist in its extraction. In the early months considerable help may be given, sometimes by introducing the finger into the mouth of the womb, with a little extract of Belladonna, to promote its relaxation, but no _force_ must be exerted in doing so. If any part of the after-birth can be laid hold of it should be withdrawn, but no extraordinary effort must be used to reach it. Frequently it happens that a portion of the after-birth remains in spite of all attempts to take it away, and there is a _possibility_ that it may produce inflammation of the womb, but no very serious apprehensions need be felt of such a result, providing the patient is properly attended to in other respects. The retained portion gradually decays, and passes away, merely occasioning inconvenience and being very offensive. The danger from leaving it except at a very late period, is generally thought to be less than that from using any forcible means to remove it. The best means for correcting the offensive discharge are cleansing and antiseptic injections. Warm soap suds are very good, or a decoction of Peruvian bark in water. Strong _coffee_ is also excellent, or a weak solution of chloride of lime. The bowels must be kept free, and the skin carefully cleansed and well rubbed. On all occasions when the hand can be introduced with moderate and safe efforts it should be so, and the after-birth removed.
