I will only add one word, in conclusion, upon this subject. Let it be remembered, that if the bowels have been confined several days, and diarrhœa comes on, that this is not a natural relief, but the effect of irritation, caused by the presence of a loaded state of the lower bowel, which must be quickly removed by the medical attendant, or it may give rise to some one of those serious evils already enumerated. _Diarrhœa._ An affection very opposite to that which has just been discussed, may occur during pregnancy. We have seen how diarrhœa may arise as a symptom of costiveness. It will manifest itself, however, independently of such a cause. The intestines may participate in the irregularity of the womb, and, their vermicular action becoming morbidly increased, diarrhœa is the consequence. It is a disease which varies very much in different individuals, and may clearly be divided into two kinds. One, in which the motions are more loose and frequent than in health, but not otherwise much altered in their appearance. The tongue is clean, or only slightly white, and the appetite is pretty good. No medicine is required here; a careful diet will correct the evil. _In the other case_, the stools are liquid, dark-coloured, and very offensive, accompanied with a coated tongue, bad taste, offensive breath, loss of appetite, and more or less disorder of the digestive organs. In these latter circumstances, your medical adviser should be consulted; in case you do not see him, I have found at first the following draught, given every three or four hours, very useful—rhubarb, eight grains; ipecacuanha, one grain; dill water, one ounce. As the tongue cleans, the stool becomes more natural, a wine-glass, three times a day, of some bitter infusion, such as cascarilla, orange peel, or gentian, may be taken with advantage. If the diarrhœa continues for any length of time, it is always wise to have the surface of the body kept warm with flannel; and this is best accomplished by a flannel roller bound gently round the abdomen. But in either form of this disease, whatever remedies are proposed, there is one mode of treatment applicable to both, and which is the most important of all; a proper system of _diet_. The food must be sparing in quantity, of the mildest quality, and such as to leave, after the process of digestion, as little excrementitious matter as possible.
