This affection is essentially a nervous one, and the only means likely to relieve it are those that have a tendency to soothe and calm the nerves. If the patient be surrounded by any irritating circumstances they should be at once removed, or she herself removed from them. Particular attention must be paid to the diet, so that no derangement of the stomach or bowels be kept up, and a regular system of out-door exercise must be practised. A warm bath just before going to bed, with a good rubbing of the skin, will frequently act like magic in procuring rest. As a general rule narcotic drugs should not be used, but in extreme cases they may be resorted to sparingly. A single Opium pill, or a few drops of Laudanum may be taken after the bath. If the patient be thin and delicate, she should eat meat, eggs, and milk, and take a little wine, if it causes no unpleasant symptoms. Indeed a glass of wine will frequently act better than Laudanum, and so will ale with some, and coffee with others. If the patient be of a full habit these things will be improper, and may injure. She should then be kept quiet, and fed sparingly. _Music_ has a powerful effect in many of these cases:--a slow, solemn air, played while the patient is reclining after her bath, seldom fails in inducing sleep. TEMPORARY AFFECTION OF THE SIGHT, HEARING, AND SMELL. These disorders are quite common during pregnancy, particularly in the latter months. Some females will be utterly unable to distinguish any odors, even the most powerful; others completely lose their taste, and others again become deaf or blind. When they are caused only by the sympathetic action of the womb, such deprivations are seldom of long duration, though they may recur at frequent intervals. In some cases they remain a considerable time, and great fear is felt that they may become permanent, but there is little danger of such a result. I knew a lady who suddenly lost her sight when about two months gone, and who remained totally blind till about three hours after her delivery, when her sight returned in a moment as perfect as before. The same thing has frequently been observed of the other senses. In some cases the vision will not be lost but perverted, and the patient will then see everything double, or larger or smaller than natural, or always of a wrong color. In like manner some will hear imaginary conversations, or will fancy everybody is shouting, or perhaps only whispering, though they are all the time speaking in their natural voice. These perversions, when thus produced, need occasion no alarm, and seldom require attention, unless accompanied by other urgent symptoms. They may arise however, from a fullness of blood in the head, in which case they are accompanied by a flushed face and drowsiness, and are preceded by bright sparks flashing before the eyes, or by ringing in the ears.
